- Automotive technician since 1991 I show how I do a valve grinding job (Lapping Valves) at home using a vacuum hose, drill & compound, don't over think it and don't assume it cant be done. learn how and save money on your project with out taking your cylinder head to the machine shop. Valve guides must be in good shape ( with no significant play or bent Valves before you perform this task, but this procedure works very well if done with care & quality. Go get it! and God bless.

This is the guy that keeps all the mad max cars running in the future
Mr.OldschoolFunk, you are one elite old school mechanic. As I younger technician I love learning from older guys like yourself. Definitely a big difference when you compare a tech in 2015 vs 1995
My Dad taught me this when I was 15 (54now) when we were freshening up my first car (67 Cougar) and the valves were leaking a bit. We used a piece of 1/4" air tool hose, more rigid and twisted less than vacuum hose. Man o man did that make a difference. Before, it would screech the tires on full throttle take off. After, it would burn the tires as long as you held the pedal down. My friends were impressed big time. I became a mechanic and built many engines before I was 20. I have since run a machine shop and now have my own shop. Good video and your technique is very good. I say all this to commend you on your talent and skill. Heck of a job on a Toyota 3.0 and the good news for all watching this is that if the valve clearance was good before, this method can save you a lot of time and expense adjusting the valve clearance since it doesn't take much material off the valve face or seats. GREAT VIDEO!
I love this guy. He practically helped me rebuild my cars
I am a certified diesel mechanic, I believe that your task is a great skill to get a job done easier and cheaper ! GOD BLESS YOU
Omg my 3000gt vr4 jumper time and bent all 24 valves just slightly. I watched this video. Pulled all my valves, paid a machine shop $80 to tank my heads clean. I bought a $51 new set of valves from eBay. Did everything this guy said on all my valves. Sealed it back with Genuine Mitsubishi mls head gaskets, new head bolts ,all new genuine timing components, gates racing timing belt, and I’m just at 3000 miles with 19t upgraded turbos pushing 18psi 512 awhp on pump gas. Did a leak down test only because I went with copper plugs and everything is perfect. This guy saved me so much money I was able to afford bigger turbos. I love this guy and video. Much love from Brooklyn nyc !!!
That is absolutely genius, you grind a bit off of the valve and the seat, and get a perfect seal.
YES SIR I watched your sanding block and head surfaces video couple months ago and know your about to learn me something good - OLDSKOOL Style. You my friend, with your knowledge , skills, work ethic and attitude you turn my garage into a classroom!
My dad taught me this years go as well. He used to build some badass engines and drag race when he was younger. He was the slickest mechanic I've ever met to date. Never had any issues using this method. Thanks for the video
Nice Job, I've doing this style of lapping for a few years now with great results. The only thing that I do different is I hold tension on the valves head with my thumb rather than pulling it with the drill and I also reverse the drill every few seconds.
sounds good
Dude I have to say I like watching your video's, I'm no mechanic but I'm a service writer who has been in the biz over 20 years and you are right str8 100% they don't teah this in school but old school techs know this brought back old memories watching you do this is how the techs at our dealership did this now days I see this young guy at the dealership which I don't call techs these guys are parts changers they throw parts at vehicle hoping to fix it I wish we had more mechanics like you at my dealership.
Dude I have been watching several of your videos and the stuff you do rivals the machine shop in major ways. You have saved me hundreds of dollars and you have been a blessing to me and others. You truly have the mind of an engineer because to me engineering is problem solving by design. Thanks again. Thank Jah/Yah for you!
First, I like how you use mechanics to spread your ministry to youth and teach them a trade . I'm a retired aircraft mechanic and love picking up tips on CZcams , never to old to learn . Have a 96 Honda 22B2 with bent valve , did the timing belt , used the big breaker bar and tool . I watch when I need some tips . God bless your ministry , our youth need to know that God has plans for their lives
worked great on my 81 Toyota 22r heads..I was just going to do the head gasket until I saw this video.. hahhahha thanks oldschool your the man!
Great Video, just about the grind all the valves on my Volvo 850R doing a full engine rebuild, looking forward to the satisfaction of being able to say "I rebuilt that!". This video has shown me the way i think i will be doing it! Thanks for taking the time to post :-)
I also do it with an electric drill, few people say it is wrong to do it this way, but then why are engines i repair still running perfectly? just because someone taught you than you need to do things one way, doesnt mean its the only way to do them. just came across you channel man, subbed.
Yes I works, we did this back in late 60s &70s..it's not a triple cut.,but It makes a ol beater& work cars run great again. .a friend pulled the head on a ol Malibu wagon 250 6cyl his father in law gave him on a sunday.. oh shit it had a burnt notch in a exaust valve..he calls & says ..Help..nothings open..he has to drive it..so I ground that valve on a bench grinder, & ground/seat..all with a drill..I did grind a margin & took a tad off the stem..for what we removed on valve..it ran like a jewel. .for years..
& mr. Hunt our shop teach in high school taught us this & we used a pencil to mark & check how it's seating..and I'm still using my dad's valve clamp he bought before I was born in 52..I even have his flathead valve tools & his dad's black smith irons & tonges..
I am glad that you showed others how to this job. I've been doing mechanics all my life. Lets just say I'm over the half century mark.
Only one thing I can offer. Instead of calling it a "Bad Boy", call it by it's real name. :-)
Cant please everybody reltub. I just handle things, get the job done and help as many as I can.
Really enjoy your videos :) I grew up learning how to do this stuff , "Old School". I have 5 kids and now maintain a fleet of family members cars :) Keep up the good work :) The world needs more Christian mentors..God bless :)
I've ground valves this way hundreds of times, I use gasoline to clean the paste off, always worked and never had a problem!
This beats the heck out of the old suction cup hand drill method
I have never done this but I have an accord with a snapped timing belt
After watching this guy’s video I’m very confident to replace a valves if they are bent. Than you for sharing your knowledge 👍🏼
I like how you show the whole process, not just the results.
Nice video and explained very well. Did a lot of motor rebuilds in my day but never touched an old head, always used a machine shop. Since these machine shops are far and few this seems like a great alternative......Thanks!
You are making very good videos! I have seen many of them, learned a lot. I like that you keep on repeating stuff when working, it "sink in" that way. Best regards from Roar(Norway). :).
man ur the boss ur absouletly know ur stuff I'm in Australia an I always use old school methods just like you that's how I got taught old school never dies never
I have been doing it with an electric drill for 25 years and have never had an issue. I tape the valve stem and chuck straight on the valve - use a combination of about 5 seconds in reverse and then 5 seconds in forward with a light pull against the valve/seat - repeat until finished. Good info.
seems like this guy has some serious knowledge on doing things at home!
Iv been doing it this way for 15 years in my own shop for customers iv had for years with no problems, Give this guy a break. Great info oldskool
great job. well explained you help people like me that like to get the hands dirty and can't afford machine shops prices. god bless you and thank you for sharing your skills.
thanks for sahring this man, old school legend
That’s a nice set up, I used a hollowed out socket and a cut piece of bed frame with bolts that came out of the valve cover
Nice oldskool funk! thanks for sharing your knowlegde/tips and tricks on engine heads.
Thumbs up man, a machine shop would have done an entire valve job. Way to save some $$$!
Thanks motherlovinsnuffstar, they charge quite a bit for the valve grinding process. You can buy a drill, rent a valve spring compressor and get the valve grinding compound all for under what they charge $150-$250 and do it your self with pride.
I like the cardboard 'false head' cylinder guide. Simple and effective. Enjoyable videos mate.
I will get some old heads of a car in the junkyard and practice, will follow what you did. Thanks for showing your video.
I am impressed.. Of course, I have access to a well equipped shop, which is why I'm impressed.....Nice.
I love this guy. Straight to the point and very good ideas. Taking care of those "bad boys", LOL
This might be the best tip I have heard on CZcams! You are a natural teacher! Thanks--
Thanks jacob decosta thats what its all about, helping each other out.
I high school shop class I hot glued a wood dowel to the top of the valve to then spun it by hand when there was not enough suction cup tools available. I have actually used the vacuum hose trick too. Great video!
Thanks rogerbeginify. Ya man that wooden valve lapping tool just wasnt cuttin it anymore to much work inlvolved lol
you don't want the drill to oscillate too much while grinding. it will work but the valve guide holes take a beating. Straight in ok but if the drill bit or hose isn't straight it will oscillate. doing it with the drill can spatter valve grinding compound and if the valve stem gets hit and it up streams to the valve guide the grinding compound can score the guides causing future issues. slow grinding is always the best. You don't want heat while grinding either. a cold polish and seating is always better there's a science behind this
I love your vids so much have helped me quite a bit while I'm rebuilding my engine 2005 pontiac grand prix gtp supercharged I always tend to search ur vids first when I run into problems thank u for all your help u saved me from royaly screwing up many times
lapping is a good finishing touch to a freshly ground seat and valve
over lapping is doing more harm than good, as initially, there is a difference of 1 degree between the valve and the seat to permit a fast tight seal,
when you're lightly lapping a new ground valve and seat, you make the perfect fit between the parts and the real contact is no more than 1/64 inch wide, as the engine runs, the contact is enlarged to nominal seat width.
when you're lapping a used valve/seat, the best thing to do is to lap lightly as the valve and seat are worn together and the guide is almost worn too and a deep lapping makes the situation worse as the real seat is enlarged, the valve becomes notched and the chance is great that you ovalize the seat and normally, a used spring has lost a part of its tension and the force exerted between valve and seat is not longer sufficient to break the carbon resulting of the combustion
It's better to have heavily lapped valves/seats that seal than to pussify the job and have a seal that will break at the first sign of pitting... having perfectly multi-angled valves and seats accounts for what , maybe 5% better port airflow. Maybe worthwhile in a spec racing series chasing those last few horsepower but otherwise it just seems like a 1950's machine shop up-sell, back when people believed every word that came through the radio or TV.

@@NickKautz Well said Nick
This is a great trick. I acquired an 06 Forester with no compression. If the rings are still good I think I'll give these tricks a try for finding and fixing the valve leaks. Thanks a lot for sharing!
Thank you Oldskool, have some valves to do myself looking forward to doing it oldskool way. God Bless and thank you again 4 sharing your knowledge..
Thank you for taking the time and trouble to make your videos.
On another note, when I worked at aamco transmissions back in the 80`s There was a mexican guy that was the head builder. He was one of the best mechanics I ever saw....not only that but I could never understand how he NEVER got dirty. I used to get kind of mad because he couldnt understand why everyone else did get dirty. LOL
Your voice kind of reminded me of him. :)
Thank you for your time and trouble sir.
Thanks for the tips. My wife and i are working on a 80's VW Vanagon. We plan turn in to a mobile shop.
Keep it grinding brother, excellent videos with awesome details and angles of the job you're doing in all your posted videos for that matter, I don't see anything wrong with your vids man, you're a true hard working man with the skills and desire to keep moving forward and investing your time to show other people that have the desire to learn as well. Always keep Almighty God in Jesus name in your thoughts and actions like you always say and everything will fall into place perfectly in your life all the time.
and i like the air leak with oil check after the fact to know you got an air tight seal before you put the head on again only to see you have compression loss... nice check wouldn't have thought of that going into it for the first time
There is lots of love for this Man right here keep helping us Thanks Brother
Love your videos. Your old skool tricks are great when you don't have all the tools. Tried the water test and have some small leaks. Gonna try your lapping trick with the drill tomorrow.
I have been doing it this way for many years.. a good way to do it. just need to be careful not to over do it.
Great video - and the new version is easier to look at. But what a difference when you show the old vs freshly ground valve. Working on my old Honda CB750 - and feel like I can give this a shot!
Thank you for an excellent video. I have seen other guys do this, just not as clear as your video. You made it perfectly clear what and how to do this procedure. Thanks for not explaining 10 other things while showing exactly what to do. I believe that this is one time that I feel confident to do this myself. Great video.
Thanks Macdoctor I actually made an updated version of grinding valves that is much better quality its called "how to grind valves with a vacuum hose and drill..." check it out it might be more useful God bless
I still use the even older school suction cup sticks. Same basic concept, just work on my boyscout fire starting skills!
This guy is fucking wise he sure knows his shit
I appreciate your videos, just used the hose and drill technique on my motorcycle head, and this morning I will use the air in the port method to check for seal- Instead of gas- THANKS Sir-
Absolutely love it man. You're making me want to check my KL before slapping junkyard ZE heads on it. I used a household steam cleaner and brake cleaner (wear safety glasses, it will hit you in the face.) to get them really clean without taking them to a shop. It got rid of most of the gold color and nearly every speck of baked on residue throughout the whole head.
Some people are speaking poorly of this technique without first hand experience. I did this on a d16z6 engine in high school that had two burnt exhaust valves (did all the valves though). The engine had 210,000 miles on it. Blew the bottom end at 245,000 miles (spun #3 connecting rod bearing and shot the mangled rod out of the block trying to baby it closer to the shop I used to work at) and swapped it for a d16y7 short block. Continued to drive it until 257,000 miles and sold it to a 16 year old girl who lived down the street. That cylinder head is at over 320,000 miles now and the girl still drives it without issue. From experience I would say that this method works fine in saving time but only if there is no physical damage to the seat and you are running a stock set of valves. I also later did the same thing to a 4g63 from a galant vr4 that was disassembled when I bought it. Still runs awesome and currently pushing around 350hp with an Evo 3 16g turbo.
Also, I'm not saying it's the right way to do it! I was short on funds in high school and couldn't afford a proper valve job. I'm surprised I never had an issue with the Honda. It was only a temp fix to get it on the road until I could afford a used head in good shape. The galant still runs awesome but I'm sure someday those valves will lose their seal due to not getting a proper valve job. Ymmv.
Soap and water for the win! Nice tip
Thank you bra for sharing your knowledge and skill with us all! YAH bless!
Didn't think of the leak test. I will try the drill bit method for my first attempt at doing this. Thanks man!
This brother is a genius...thanks for the knowledge.
learn something new everyday thank u my g...hope this stays in my head when the day comes...
Love your videos man, you do great work with every job I've seen from ya to say the least!! This guy shows the importance of attention to detail. Well done sir!! Keep the videos coming my man, thank you!!
GREAT VIDEO OLD SKOOL!! Either the thing seals or it doesn't. There are other videos with machines that look like they cost 10k or more. What do those machines do? Get your valves to seal in the head that's what. Seat of the pants approach that works, and you prove it. What I am sure is that car is going to run and those valves will seal like they did on day one. How long? Who knows, I have to think for a good run down the road at least. By that time it will be ready to swap in an LS1. LOL probably not but I have no doubt it will work.
Thanks! Sometimes different methods are so obvious after you see someone else do it. Kinda makes me feel stupid that I didn't think of it before. More power to ya. God bless!
just wanted to say thanks for the information i used this method and it saved time and it worked out great.used it on my busa head. thanks again
+David Kenlock-Coleman im sorry David it will work
Finally a vid showing how real shops do heads
Nice thing ! I used to do it whit the suction cup on end of valve and rotate it by hand XD Drill is one new trick ill use thx a lot !
You are awesome, we need more like you .
I am on my way also ; ) thank you for the great videos and kind words. I am now about to start repairing Heads and gaskets for cheap so people don't have to lose their car because they are not a mechanic and can't afford to pay more than the cars worth to fix it.
+Steve H Right on Steve Thats what it is about HELPING EACH OTHER. God bless.
Wish I could've seen where you was putting the air hose to check for the leak, but thanks for the parts we could see, great vid
its either the exhaust or intake hole, depends on which valve you are testing
You just great on what's u do bro keep doing it much luv
I like the vacuum line trick. Pretty beat way to hold on to that bad boy
I did it in a slightly different way, and I will share it right here in your video, because some people may not have access to the same tools of yours. I just turned the cylinder`s head around and pour some gasoline in the intake and let it there for a few hours... to be honest, I didn`t even know that the valves had to seal , I just thought it would be logic if they did to keep the compression.. so I had these two cylinder heads here , old ones, and started to do some experiments, cleaning and such.. adding gasoline inside the intakes was very easy to do and the result was visible in a few minutes later.. I suppose it wasn`t sealing properly because of the thick carbon layer around of it.. cleaning it properly without grinding solved my problem.
Thank you Antique.
Thank very much sir
I love learning from your videos
good detailed instruction and good to know how to it, i can do my own valves now...... thanks oldskool
great tip-will do to my vw-i happen to be doing a ring job and was going to do old way. i like your test for leak. thanks!
great idea dude! thanks for the info! Definitely not taking my dirtbike's head to the shop now! You saved me some dollas fa sho! Keep the vids coming! Very much appreciate the tip
Another fine video for alternate rebuilding methods. It is interesting to read the comments ffor your videos. It appears that the more experienced engine rebuilders are resistant to any machining method that does not utilize the most expensive equipment available. If the process does not employ tried and true practices of which the machinist is familiar, then the work is doomed to failure. This is an example of our society where personal skills are no longer being taught to our youths. Young men used to compete with their cars and almost every young man could could tune up his car and perform simple maintenance. And a significant portion could hop up a car for better performance. Today cars are so specialized with their electronics and tight tolerances that young men are no longer able to work on the cars. Maintenance and upgrades must be performed by specialist who are taught very specific methods of repair. If the methods are not followed exactly then it is wrong and it will fail. This dumbing down of our society is robbing our youths of the skills to do anything beside running a computer or watching tv. Your method of lapping valves may not be factory approved, but I bet it works...and it will give the young men who have the ambition to learn new things the satisfaction of building their own engine...for pennies on the dollar. Look at some of the methods our great grandfathers used in the Great Depression, they used their ingenuity to build and repair things, they could not hire out the work. Skilled workmen have lost the respect of our society, someday soon those same skills will be held in great regard. Keep up the great videos, Merry Christmas
This video is awesome!! Thanks man.. Now if only I had a keeper tool I could get this thing done tonight!!
This is the perfect vid at the perfect time. Thank you!!
you 🐕 you..you saved me big time and $$..thanks for the video.
Love you man.got a dodge. Thanks
It works for me everytime I grind and lap valve.I always get a gasoline tight seals.
Bro, thank you for your videos man... they helped me tremendously.... Respect man..
Now that's how you do it and it works that's why they won't teach it because shops lose money
God Bless You,You are Amazing
Say man...great video. Great ideas. Fan forever. Keep making them.
Right on Walter, I will do so brother, keep your head up out there.
a used valve re lapping must stay light because the wear pattern of lapping tends to deform the valve contact area and widen the seating area so the valve seat becomes more sensitive to carbon buildup.
I relapped new valves on an old seat very often when the valves hitted the piston on a timing chain failure on a medium mileage car and I never had a comeback on such a job.
I never done that on a burned valve as usually the seat is damaged too.
Prefer to do it by hand so you can turn the valve 180 degrees nothing wrong with using an electric drilling machine though you are a great guy godbless us
This video is on point. Thanks! 👍
Thanks man! Very detailed and helpful! I like the hose "trick".
You can also use a socket, extension, and a hammer to get the valve springs off. Easier and cheaper than getting the tool, unless you are doing a bunch of heads.
thank you :) your videos are so helpful and saved me alot of money
Keep up the good work
lol bro your a beast. Love all your videos you need to make more. Smash them get out there and handle it get the deal done.
Right on itsme2369 I will continue to add more keep your head strong out there bro God Bless.
Yo man by any chance can you make a video on fixing a gas gauge not working and the gas light stays on. Its for a 1998 Audi A4 Quattro.thanks brotha in advance god bless.
your the fucking man I learnd so much from some videos you made thanks for sharing I hope you have much success with your channel👍
That is pretty neat...
.
That would be a expensive job if you where to do it on your own. You'd have to buy a specialty valve reseating tool, and most likely bring the valves to a machine shop to be resurfaced! I bet you know how to smoke a possum out of a hole too!?
