Did you use the same tool to install the new stems?
No i took it to a machine shop. Infact you should not do this. Its way safer to have the machine shop remove them. Its not even expensive either
you have to heat the head up 90 degrees to remove the guildes safety, doing it cold will mushroom the guildes, damaging the guild hole.
Yes I know ,I was just being cheap. I've taken the head to the machine shop and had them install the new guides .all is well
I would put it in a freezer for one hour. The guides would nearly fall out.
@@lean5gb interesting' i will try that, thanks
@@lean5gb that would cause the head to shrink and be tighter on the guides. Yoir freezer is not cold enough to shrink a guide.
@@lean5gb exactly! thats what we do on massive diesels on ships as well.
I'm no expert, but I think thats the installation tool. I think you should have to drill out the old guides. But, if it works, it works. Drilling is probably easier. A lisle 59000 tool kit i think is the proper tool for removal.
Great clip! Usually machine shops overcharge for that kind of service. Thank you!!!
Id recommend not doing what i did in this video. If i could go back i would just pay a machine shop
@@themechanic6117 why ?
It's 3asy to cause damage doing this and possibly ruin the cylinder head. It's inexpensive work at a machine shop. Just pay them to do it right
@@themechanic6117 I'm assuming the tool opened the hole the valve guide sits in and when u went to put it back it was loose. Didn't check the OD?
Mine turned out to be fine but yes that's the problem that can happen
A $1 5x50mm Allen bolt and a drift will work too and you won't bend the tool either. Now the tool head is bent (it doesn't slip down the guide 100% anymore as you've found out) it will gall the softer bronze guide when you try and install it as the bend will have to correct itself using the ID of the guide and it will scar the guide. Also use a 3lb mallet as it does not have a hardened face like a hammer and wont chip anything like a punch or a grade 8 bolt. That's a great price for that tool, just a design that is prone to bend the turned down end if you don't hit it exactly square with the mallet.
Well apparently this isn't the thing to do anymore according to the comments :-)
But this video still taught me another small piece of how an engine is put together. Didn't know valve guides existed but have sort of wondered how valves were mounted. I guess these guide pieces are a starting point. Thanks for sharing stuff.
Yes, dont do what i did. Its cheap to pay a shop to replace guides👍
I liked and subscribed. I like the way you describe things. It's very clear and has just the right level of technical detail. Camera shots are pretty good, too.
If I could suggest any improvement, I'd say maybe a little editing to delete the parts where you walk from one part of your shop to another and any dead air time. Otherwise great, and I look forward to your future educational videos.
+Lack of Focus thank you for your comment and sub.if you watch any of new videos you'll see I now do delete all of the wasted time.
Dang, those guides are in there! I’m gonna use a 3 lb hammer lol
Its best to let the machine shop do it. Faster/safer
Nah, the whole thing is getting scrapped. Need to separate the Al and steel
@@MrDannyd9 They must be paying pretty good for scrap metal where you are to make that worth it.
Good job.
On a junk head, ok, whack away. If working on a good head- it's best
to use this to press guides in & out. No risk of cracking or slipping a hammer,
shocking blows like that crack aluminum very easily. If you don't have
an Arbor press, either use your car, or take it to a Machine Shop.
Slow, steady pressure is just as effective.
I tell anyone who watches this video to dont do what i did. Pay a machine shop to do it right
😮good cheap tool💯
great video, not a bunch of bs
nice
Maybe next time do it on a work table with somthing soft under de head so you cant get any damage on the head like u can get with working in the floor…
Man if you could have installed it on a air gun it would have been quick . 👍
At this point i didnt have a air hammer. I honestly regret doing this. Easier to just pay my machine shop a few bucks to do this properly
@@themechanic6117 why would you have payed a machine shop to have done the Thai?
This*?
Because it's cheap for a shop to do it and they know what they're doing. High chance of damaging your head doing it like this
i wouldnt let you fix my lawnmower
Looking back at it this is cringe worthy . i should have let the machine shop take care of it like that did for everything else. Well its a good thing i dont work on lawnmowers 👍
hey, in here malaysia, they recommend me to replace with new cylinder head, it can be repaired, right? grr
+DJRV REDVAMP because of bad valve guides ? They can be replaced
DJ RVSK
Just heat the head up in a barbecue for 20 minute before and they will fly out
Do you have a link to the valve guide remover? Have a name of the tool or brand of tool?
I dont recommend doing this. This job doesnt cost a lot at a machine shop. Let the pros do it
How do you install them?
Have a machine shop do that
What's the link for the tool
AlphaKillo here you go.
Look at this on eBay www.ebay.ca/itm/311713206219
double check to see what size u need
+BACinthegame I'm not going to take that chance and possibly damage the guides,I'm paying a machine shop to install them.
The mech a nic hey if I'm going for just a rebuild and not replacing the valves. Should it be ok to just get the seals and not the guides? Not sure since your replacing new valves, thanks
Will Alexander check to make sure there's no play in your valve guides.if there's excessive play than you'll want to replace the guides
The mech a nic if there is extra play then you need to see if the valve stem seals are too narrow. If they are not then the valve guide needs to be replaced. If they are too narrow then the valve guide needs to be replaced or sleeved. This was a good demonstration of valve guide removal thank you
I think and air hammer would be best my dumb ass would miss the remover tool and jack the head up lol
Dont do what i did. Its best to just pay a machine shop
Houla vaut mieux chauffé la cullasse avant l'extraction sous peine d'arracher voir pire fissures l'emplacement ce qui arrive très vite car yas des endroits cest très fin .. donc chauffé et extraire de suite le guide sans perdre de temp il faut sa soit fait en un coup trez rapide.ensuite pour les réinstaller les guides il faudra realeser le diamètre du guide neuf avec un forêt spéciaux pour qui ais les bonne côte. Et rectification siège de soupape....
That was painful to watch
Yeah i dont recommend doing this. I should have just paid a machine shop to do it
wear glove
Can u use the same tool to install it too?
No, the entire head needs to be heated up then the new guides pressed in. Machine shop does that
With my luck...I'd get the tool stuck in head
I regret doing this. It's too much work. You can just pay a machine shop to do it quickly and it doesn't cost much
@@themechanic6117 Was the machine shop way just using a press? Or did they do a drill out method?
Over here they press that out i believe. They might heat up the head first
@@themechanic6117 Thanks! I have my buddies 2012 5.7 challenger that we cammed and the person he had do the headgaskets did them backwards. While going in to do them the right way I found that one of the guides is broken and half of it is just sliding around on the valve. I have a press available and the tool that you used. I can heat up the head with a torch or heat gun and freeze the new guide. If its anything like pressing in and out a wheel bearing it should be smooth. What are your thoughts?
Correct way to remove guides heat up the head in the oven for the right amount of time and the right temperature use the tool with a air hammer safest way to remove guides and install them make sure the guides are chilled and the correct lubricant used to install guides taxi I am retard machinist there is a correct way to remove guys without damaging the head or damaging in your new guy when you put them in it's called professionalism learning from a pro and being a pro
Correct way is to let the machine shop do it. I regret doing this. Easier to just pay the pros
Apparently freezing the whole head is an option to help remove the guides, though I've not tried that method.
I like living dangerously so I will have a go replacing guides on a 4.7L dodge with a lathe-turned driver, and pre-heating the heads to around 300F if I recall. If I go overboard with heat I know the seats will start falling out by themselves. I will have to research the guide lubricant, and I know the new guides need to be chilled, preferably with dry ice but perhaps just a freezer will do it. I have seat cutters to clean up the oem seats, I'm not brave(?) enough to mess with the seats.
@@archygrey9093 easier to heat it up in a barbecue unless you have a big freezer
@@tamar5261 I imagine it would also be easier to accidentally warp it on the bbq from uneven heating too, also it would be much safer and easier to physically handle out of the freezer, I've heated quite a few parts and someone or something almost always ends up getting burnt.
If someone doesn't have a big enough freezer then perhaps a couple of bags of ice dumped on top would work.
Thats if freezing does actually work, I've only used freezing so far for getting new bearings on.
Hack didn’t even put it on wood
This head was scrap. I thought i mentioned that in the video. I wouldn't even recommend doing this. Take it to a machine shop and pay them to do it correctly
Lesya, your comment proves you to be an idiot.
