Make sure you head over to the new @SBIVavletrain CZcams Channel! www.youtube.com/@SBIValvetrain
We've been using their parts in our shop for decades! Really appreciate them supporting us all these years!
Do you ever cool the valve seats (and valve guides) in dry ice to make it easier to press them in ?
High Quality parts and Service
@@NICK-uy3nlyou can maybe icebox them
Do it right the first time and you get the customer back with a different motor and they will tell their friends about your quality of work
Thank you for using SBI! We appreciate you and everyone's support through the years!
Good on you guys for sponsoring Jim's! This channel made me aware of your products.
Good products. Have used SBI for a long time. Thank you for supporting the channel
I worked with with many companies that sold SBI, but you guys gotta make more parts for these classic cars though.
Thanks for sponsoring these honest guys, they deserve it.
Man, I love you and your dad’s relationship. Honestly I’m jealous. You guys are great.
My father passed a year ago tonight, I definitely wish we had a much closer relationship like this compared to barely ever talking.
My dad died when I was young over ten years ago now probably more than 15. It's always great watching these guys
My dad died in 78 and every year he still gets a little smarter than me 😂
My father passed in '18. We were close like this. Camping, dirt bikes, construction. He taught me so much. I miss you pops.
Agree, the relationship is superb...I don't know who is enjoying the moment the son the dad or his mom.. one of the moments dear he wants to have a you tube video with you. "Oh he'll no don't mess with me.." and look now.
Your old man is so humble I love how he focuses on everything the previous machine shop did well instead of crucifying them. Y'all are a class act and you're lucky you get to call him "Dad"! love the content.
💯 when something is not as he would do it, or doesn’t know why, he says he doesn’t know and assumes they were doing what they thought was right.
“And make it as good as we possibly can.” That’s the kind of work ethic that allows a human being to lay their head on the pillow knowing they did a good job for their customer. Well done!
absolutely!!!
and the Attention to Detail and the High Quality Work is off the charts
because if the work isn’t up to their standards, then it doesn’t leave the shop until it is up to their standards
What an absolute JOY it is to watch this channel. A guru father teaching his craft to his son. Doesn't get anyy better than this!!
The best thing to me is not only the positive relationship they have, but that dad is open to learning from son as well as the other way round. It is how all good teaching/learning situations are, we work together. Incredible content, wonderfully relaxed, and lovely genuine people. Thank you from Down Under.
No other success will compensate for failure in the home
"Cleaning guy" tells you that you need to clean up your mess. 🤣
I thought that 😂
Came here to say exactly this.
"Cleaning Guy" needs to stay in his lane! 😂😂
I was shocked when you looked in the Chilton book for the specs.
Im 59 years old.
My dad owned a shop when i was a kid.
We had Chilton books for everything.
All our time for painting and repairs.
Keep up the good work 😊
Total blast from the past!
I've still got all my Chilton's manuals, and many of the service manuals from over 5 decades of working.
@@Wheel_Horse That's cool. They're nice to have
@@montymartin4493 Yeah nice to look through them and reminisce, but little use to me any longer. I should part ways with a lot of my junk so my family doesn't need to get stuck doing it when... you know...! ⚰
Starting in the 70’s first thing I bought for every vehicle was a Chilton’s hardcover until soft cover came around. Now for my 2020 Sierra seems to be online only.
The slow motion of Dad with the big hammer and the smile is priceless.
There’s only one thing I dislike about all your videos and that would be when they end. Can’t wait to see this ol’ 235 fully assembled 👍🏻👍🏻
I am beginning to suspect the cleaning guy knows more about stuff than we are led to believe. 😂
Thanks SBI for supporting the channel
Worked in a trade over 20 years. When you spend that much time, if you're good at what you do, you pick up little sensory cues of something going wrong before most people would ever think there was problem.
14:43 , your father knew right away the tone change of the driver on the vale seat was wrong with the impact driver. He didn't force the issue, moved on to the next one for the time being.
Its those fine little things I love seeing in all these videos I watch, a testament to how much experience your father has, how his primary senses of touch, hear, and feel is better than any manual in print or tool made to do it better.
If anyone sees and appreciates the same, the crank grinding vids are a masterpiece of pure sensory operation while simply watching a simple dial on the machine.
Thank you gor a great channel. No stupid music, needles jump cuts. Love the slow motion. Your videos should be used in trade schools.
Fact dude music would send me
I absolutely love the interaction between the two of you and the calm explanations.
None of the typical shouting that you see so often.
Just two people with a great work ethic doing the thing they love and are good at.
You have such a wonderful relationship with your father, it's such wholesome content honestly.
The level of knowledge and raw experience he has just shines in these vids.
Nice professional job, by nice professionals, in a nice clean professional shop. Terrific work! Thanks so much for taking the time to make the video!
The shop is clean because "The Cleanup Guy" told his son to clean it up. :-)
I really enjoy watching you guys. My Father is in his 80s and a retired Machinist. I learned so much from him just understanding what he was trying to tell me. That and doing the Math changed my path over 40 years ago. Thank you...
I was lucky enough to take a tour of both of the shops after making a delivery for them they are truly craftsman
A good automotive machine shop is peace of mind.
Yes Jim:)
Every time we watch your channel…
We learn something.
Especially the crank grinder:)
When you put stop bolt in between the crank weights.
How flexible a Big Cummins Crank.
Jim - you can also straighten a crank if it’s bent.
They jack it in the bent spot.
Use a soft race driver and hammer ..
Give it a wack about the fillet section:)
V - Blocks hold the crank on each end.
Then you hack on the low spot
Sometimes it has to be repeated 2 or 3 times
After it’s within .001 or .002
Put it in your grinder and start grinding
Nice job gentlemen, What a team. Not many realise how much specialist equipment is required to PROPERLY overhaul an engine. I can appreciate how much Jim has had to reinvest back into the business over the passed 40 years to ensure his customers are provided the best service possible. Its your turn now Nicholas. 😊👍👌
Love y’all’s videos cause there’s nothing better than a father and son working together and having the relationship you two have.
Gotta say I'm loving the content. As an HD tech that's almost always going in blind as a jack of all trades, it's very refreshing to see an engine master at work!
Beautiful job, the customer definitely took that head the the best place for a rebuild.
Ahhh, the trusty ole Heinz assembly lube...good stuff 😂
Wow I have learned so much and I am 73 year old retired technician for Ford and Chevrolet. That was one fine looking 235 Chev head and I have seen several of them. I used to drive a 74 Corvette 80 miles some days to pick up parts on emergency jobs. All the other technicians would complain because they didn’t get to do it but I could do it on my lunch time. It had the 300 hp 327 cui engine and it was smelling like burnt paint and hot brake pads when I got back. It would cruse at 100 mph and do 140 mph on I 70 in the Missouri River bottom interstate. No State Patrolman could catch me. It stuck like glue on the secondary curved roads.
I really appreciate your channel. I have a 45 year background as a prototype/ toolmaker machinist and I really appreciate the difference made clear. Keep on making these videos.
thanks so much for all this. I have only carried my parts over and say do this. Never seen it done with an explination of how and why. Never seen a man using a hammer on a motor and smiling. Every time I see the hammer used its with bright colorful language.
@34:00
THAT... is a happy man, well satisfied with his life, his work, and his present company.
That is NEAT to see. ❤
That’s the one we sell surface jobs with! Gold! You guys are great. Thanks for the videos!
I really enjoy learning from you two. There’s no drama no undue stress just a great couple of guys showing the rest of us what they do. Thanks to your spouses for supporting you two sharing with us.
wish i could learn how to do this work, been a mechanic/tech all my life and have always had a respect for the machinist.
Damn fine work! I always went the extra mile for my customers, loved the feedback
-former engine machinist
This woman is a gem of a person. Hope she is truly loved!
I find your videos helping me understand more of the technical side of engines. Iamwhat is known as a "BUSH MECHANIC" in Australia. This is a person who has no formal Qualifications but has abilities enabling them to successfully carry out repairs including rebuilds. My vocation was as a Power Station Operator. In the good old days you worked in small local power stations where you were operator, mechanic etc as you were responsible for keeping the beer cold. I learnt a lot of my mechanical knowledge from our local Italian mechanic and frommy Uncle who ran a workshop which serviced the local farmers and used to do things such as forge welding, and he had his own Acetylene generator for hot work.
If either those gentlemen saw you fitting guide valves in the manner you used, you would be shortly sitting in a Doctors Surgery having your hands checked out from a collision with a tyre changing bar or something similar.
Something i learnt about fitting of interference bolts sleeves valve guides is it must be done in one movement.
In the case of valve guides, I Would use a drift and some form of press and single move push them out no cutting or grinding allowed. This preserved the hole in the head and didn't create chatter or waves from using a hammer. Also kept the metal temperatures as low as possible. Each blow of the hammer creates friction heat.
The trick was tocool the valve guides relative to the head. Usually the whole head was heated to about 100oF by either leaving in the sun, or adjacent to but not in physical contact with a stove or the workshop heater.
In the case of the italian, he had access to compressed CO2 and had a modified drift through which he would inject the CO2 down through the valve guide. The press would be set up and the pressing out would begin. About 5 ton of pressure would be applied and at the same time trickle of CO2 would be released through the guide. After about two minutes the guide usually moved.If not the press would be pumped up but I never saw the press to go above 15 tons.
My uncle did not have the luxuory of CO2. He used compressed air. He was the proud owner of a 10000psi compressor and when coupled to a small submarine air tank enabled him to use air instead of CO2. He later progressed to nitrogen when somebody put him onto an oxygen generator and the nitrogen was waste. He actually built the high pressure compressor for the nitrogen himself as the other compressor was busy filling O2 bottles.
The fittingof the valve guides was easy and involved the use of the most valuable equipment in the workshop, the Beer Fridge. The freezer compartment was good for -18oC (0.4oF). For my uncle the delivery point for valve guides was always the freezer.
To install a jig would be assembled to create a stop for guide as it was fitted. The head was preheated as per previous. a smaal amount of lubricant was smeared in the hole. Each giude was removed from the freezer as it was to be fitted. Generally the guide would beable to be pushed by hand . If the guide was tight a brass drift and a 2lb hammer got in home.Now days liquid Nirogen is avalable.
Cheers
Good ol' Chilton manuals. A literal wealth of knowledge and information at your fingertips .
Some people see paintings as art I see work like this as pure art. I wish I was this skilled.
36:14 Cleaning guy out here shaking hands with danger for 40 years 😂😂(edit: also the smile while he used it you know hes thinking about the comments the whole time 🤣)
The skill, knowledge, and experience on show here, is off the scale. You have a very special father, love and cherish him every day. Thank you from London, UK.
From a man that just recently lost his mom . Take advantage of having her make you lunch every day . Moms cooking is always the best and once you cant get it anymore you realize how much you loved it
I'm so sorry for your loss 🙏
I see you got the SBI cookies on the workbench.
Today in Canada it's family day. I'm glad to see the wonderful relationship you and the cleaning guy got
What an awesome thing to watch on family day
Hope you enjoy those cookies together
Jim is very thorough in his explanations but makes it so a novice in machining can understand. Great video series!
Great idea to put the paper towel down on the table to catch all the swarf, reducing the work required to clean your machine when finished. R.O.A.R wipes (Rag On A Roll), the cornerstone of machine shop cleanliness for the past 30 yrs. 👍🇦🇺😊
You two are an absolute joy to watch work together, and are walking encyclopedias of machine knowledge.
Thank you, and keep up the good work!
I like how your seat cutter varies the speed so as to reduce/eliminate chatter.
Those Valve Guide Seals almost look like the Perfect Circle Valve Guide Seals we used back in the 60's we Built many a Engine back in those days using them and never ran into problems using them. you two do Great work and i am amazed at all of this new technolgy. at 75 i am learning alot from you both. thank's.
I came across your channel about a month ago and I absolutely love that you guys work on everything, from farm equipment to out of the norm rare engines. You and your working relationship with your dad reminds me soo much of my younger days spending thousands of hours working in the machine shop with my dad and uncles during race season. Love the transparency and explanation of everything. Everyone keep yourselves and love ones safe and healthy and remember to SMILE 😊God Bless 🙏
A genuine, auto machine shop. Very well explained with outstandinng camera work. Two generations and their differences, as well as similarities, of techniques used! My new "go to" shop show. Good stuff, guys.
All, machine shops are not, created equal. So helpful, for the machinist to have knowledge of old engines and the old books, to back him up!
Great editing! Great education
Thanks for watching!
I had thar motor in my 1952 Chevy and in my 1954 Chevy.
Long ago now.
I enjoy watching you and your son working together.
God bless y'all
I have no idea wth you are doing but I am impressed.
Sorry.
I love diagnosing engine failures and building them and now I know I love watching other do it too. Good job boys!🍻
I would say that you have a pretty good cleaning guy there. He seems to catch on quickly.
Vinton positive seals started using them in the early 80's and never had a failure.
What even are they tho
Same here. Our local machinist has been cutting the guides on SBC engines to accommodate SBF positive seals for years and it definitely helps with oil control issues.
I've seen a few of your videos about the venerable 235...I had one when I was 12 years old, in a 53 Belair convertible...early 53, with poured rod bearings...my Dad and I rebuilt that engine in the backyard, on sheets of plywood. We cut up beer cans for main bearing shims. Wound up rebuilding and installing a 56 235.
The ‘cleaning guy’ is clearly not just the ‘cleaning guy’ but a machining grandmaster. “Nah, I’m just a cook” to quote Steven Seagal in Under Siege.
I’ve watched a lot of CZcams videos but this is the most completely satisfying one I’ve seen.
I love your videos. These are honest, calm, and clear demonstrations of how to do this work properly. I doubt people realize how many machines, tools, and cutters are required to do a "simple job," like restoring an old straight-6 head. Beautiful results!
Your pops has an amazing wealth of knowledge, talent, and experience. Wished I had stayed working at the machine shop out of high school in ‘89. I build (assemble)engines a lot, and have probably done around 200 of them to date, and do “simple” valve work that doesn’t require any major machinery. Just finished a 5.4 supercharged Ford…what a learning experience. Keep up the great work at the shop and in your content. Appreciate your time to make these videos
A definite pleasure to watch a master machinist at work. So cool!
I love how clean the language is in these videos so wholesome!
Man, that Cleaning Guy sure is a Hard Worker… I’d keep Him!
Fascinating. Experience is still the best teacher. The 'cleaning guy' is good!
Love that automotive machine tool he is using, such an ingenious design.
I always wondered how all this was done. Thanks to the magic of technology, I now know. Thanks.
Been doing job shop machining for 25 years and most things that come in the shop bores me. Engine machining fascinates me as its something I've never had a chance to do and watching you guys work is very enjoyable.
Havent watched a huge amount of the content from this channel but when I do I always love the attention to detail and my god, the KNOWLEDGE you guy's posses. Its remarkable and makes me want to learn machining from you guys haha.
I wish I had you both when I was younger and working on my cars. You two are amazing to warch.
Thankful for JAMSI - Great entertainment and instruction !
Safety is everything in your trade, give those tulips a grind to clean them up please. I have had good experiences with those valve seals on the older motors.
Here in Denmark, we call it beard
In terms of doing JUST enough to get the old guides out without harm, while being super "civilised" about it, I'm deeply impressed with the is man. Even that stage was a work of art. Are you playing with us, or planning for hot-dogs later.
Thanks SBI for sponsorship!
Learned a lot on a Sunday evening, thanks for the upload 😊
Looks Perfect and Kudos to SBI. Thanks
How many valve guides did the "cleaning guy" break off? Hahahahahaha. I loved the ketchup bottle and the obvious joke. I'm looking forward to the next video.
Friends...this is DECADES OF EXPERIENCE - FANTASTIC MACHINE AND HAND WORK!!!!! WOW!!!!
Learned many things from your videos, the number one thing is to have patience. Thank you
For some reason this is SO satisfying to watch. Nothing like watching you cut valve seats.
Always enjoy the videos. Thanks for sharing them. We have our own Augie Doggie, but his name is Max. 12 years old and spends the bulk of his days sleeping. A few times a week he goes down and checks on "his" flock of chickens, but most of the time just phones the check in. :)
I thought of THOR when Dad was pounding in the valve seats in slo-mo! LOL! Excellent job gents!
Keep up the good work guys! What you are doing is a lost art, the last couple of generations have no interest in being able to do the precision work that you do. And it's so nice to hear you talk in thousandths and not the metric system!
Thanks for bringing us along with you as you make repairs.
Thanks for the content, it is so neat to have a machinist that works on things that I understand what they are!
Love watching, seeing a little of new school and old school mix every video is a new adventure. Can’t wait for another one, keep on the great videos
Love to see the tcm 25 get used, I always enjoyed working on that machine in school.
When you are cutting seats, those long curlys mean there's nothing better. Cutting continuous all the way around in an even perfect plane.
The blue valves, I had a 85 crate 350 the carb has a factory set bowl adjustment that I had to reset to stop the lean fuel mixture on acceleration. Headers were glowing red. Wow 😮
We also oven clean all of our iron components, if a head has removable guides we always remove them before putting them in the oven, most often simplifying the extraction process.
We generally do as well; however, in this instance we debated not replacing all of the guides. Once it was cleaned & we checked a bit closer we decided to go ahead and replace them all!
@@JAMSIONLINE Nothing happens by chance in your shop.
Watching "The Cleaning Guy" is like watching Gale Banks, you are learning while watching.
I read somewhere that knurling the valve stem is a "quick" way of tightening up excessive clearance in the guides without replacing them since knurling the stem increases the diameter.
You have an awesome channel here loaded with the "right way" of doing things --- very enjoyable!
I agree - that's my understanding of why valve stems are knurled. In the case of the previous machinist it made a the already 'tight' valve guide situation even worse.
Man I love watching this channel and I don't know anything about engines. Wish I did tho.
Keep watching, soon you will! Lol Thanks for being here!
never too late to learn!
At some point watching enough engine content you'll start to figure out and it'll click :)
It is a true pleasure to se the guy´s going old school, and fixing an flat six head with real machinery, real knowledge and real manual labour. I myself has renovated several cars and many engines, and i do feel sad that increadable know-how like this, is going to be lost in just a few more years. No youngster is going to let their phone down for more that a few seconds, and to learn something like this takes years of dedication.
It's not a flat six, it's a straight six with overhead valves, first built by Chevrolet in 1929, when the competing Ford A only had a flathead 4
I’ve been waiting to see this one and looking forward to the next chapter. Thanks,great job
Love the videos keep them up they are something different and something very entertaining and enjoying to watch when they come out each time.
We have a 235 in my grandpas 3100. We need to start it some time this year. Its been over 2 or 3 years since its started and ran.
You should consider using a like light oil to spray in till it stalls if you can't run it awhile I've had good luck with it with small engines it's a little extra work to start them again but it's almost always just crank a bunch and clean the plugs
Why does it NEED to be started? If it's just to idle it for a half hour, you're doing nothing, in fact more harm then good!
@@alro2434 I've seen alot of stuff rust up because the oil falls off like the cylinder walls and the cam lobes when it sits for a long time it's mostly fine in a climate control storage but most garages or just outside it'll act as a heatsink so it'll be cold in the warmer day and collect moisture in alot of places maybe not in a desert but definitely where I live. Sure starting it will cause some ware but it'll recover everything in oil, it's best to drive them even a little your right it's good for the rest of the drivetrain too
Hey, I like these videos with engines that are as familiar to me as to the back of my hands! , ...On the chipping of seal and valve driving tools which get hammered on; I welded a ring of mild steel like 7018 around the edge of the offending tool and that would hold for quite a while and stopped the more "chunky" parts from hitting my face (even with glasses on.) like the one that finally woke me up on safety musts!
You guys are easy to watch and the videos are done in very good taste, you got my vote! Best regards, John.
Great video content. from an old bush machinist from down under
Total craftsmanship
Ketchup, yes Heinz is my favorite 😊
Way back in the late 70' when I was working after hours for the local Chevrolet Mechanic, we used valve stem seals for the Vega engine on small block chevys, they fit perfect with no cutting and yes we would leave the oring off.
Same style used on this head but a direct fit, and excellent oil control.
Great Video.
