Head Work

[american-rice]

I just purchased 264/272 cams, 3g lifters, springs and retainers and I plan on taking this project on in about 10 days. First time doing this so I am looking from input or helpful links on the subject. (yes I have looked at posts on this, I just want any input that will help) I really don't want any painful learning experiences. All suggestions appreciated

So what's your question? Are you looking for help on how to install the cams, lifters etc? And if so, is this the first time you have worked on the head of a combustion engine? If so do you have a 4g63 engine manual (if not that will deff help out).

Yes this is my first time. I have read a good amount on it, and I do have a manual. I guess my question is If anyone has a good link with pictures and or pointers to make the job go smoother.

Are you planning on doing this with the head on or removed from the block ? You can do everything except springs without a great deal of difficulty. The springs can be done without removing the head by using compressed air in the cylinder or feeding a rope into the cylinder through the spark plug hole and turning the piston up to jam the rope against the valves to hold them up. I don't think it is a job for someone with little experiance as it requires a special spring compressor and is quite difficult on this engine even for someone with my 30 years experiance. If the head is removed I would take it to a machine shop and let them do the springs.

Call it personal pride, but I really like to work on my car. The last thing I want to do is take it to have someone work on it. But if thats what comes to then thats what I will do. If I was to keep the head on the car I read about hooking up an air compressor to keep the valves from falling in. But how reliable is that method? Or is your rope method the better choice?

Remember when using compressed air to hold the valve up, the compressor must maintane enough pressure to hold the valve up.I have used both methods. when useing the rope method make sure you place enough line in the cylinder.I like to use cloth line. It sucks to watch the valve stem dissappear down the valve guide.

sorry It should read CLOTHES LINE

Would this work on a DSM? On my buddy's Supra he compressed the valve springs with a notched piece of PVC and a magnetic reach tool to grab the retainer clips. The only downside is he said he just about broke a sweat.

This isnt a job for a rookie. You have to take the timing belt off to do the cams so I would just pull the head and have a machine shop do the work. Not a bad time to install ARPs and a new head gasket. Have them do a 3 angle valve job, clean up the bowls, and slap it back on. I would replace all timing components too.. assuming your car hasnt had the head gasket replace,d timing stuff, etc.

Goodluck

The only way I am taking the head off is if I drop a valve into the cylinder. And I don't see that happening, but who knows.
