Newbee here ~~Replacing Cylinder Head

[Pit_N_Bulls]

Hello,
I'm new to this board and would like to say hello and hope to be a positive contributor and member.

I've got an '87 22re engine and would like to replace the cylinder head. Parts are very expensive here in Hawaii and so I would like to attempt and do the job myself with the help of a chilton manual. I've done some work on my 4runner , like replacing starter and clutch, but nothing like pulling an engine apart. Now, with this in mind, can I do the job myself or is this something I should leave to a pro. mechanic? Any special tools for the job? Has anyone done this before and ran into problems? I've already got a new Head on order and should arrive in about 2 weeks. Thanks in advance!

BTW, my engine has 98,000 original miles and should I replace anything else other than the head? The reason for replacing the head is because of a blown spark plug while driving. This caused the threads to strip and unable to use the re-tapping tool sold at most auto stores.

head replacement

Couple of things to consider before starting this...

1) Is the head complete with valves and springs already seated and adjusted?

2) Do you have a couple of days to work on this to make sure everything is tightened down and secure?

3) Do you have the tools you need to complete this? (torque wrench, rachet set, bolt extractor, tap & die set, etc)

4) Do you have a friend that is a mechanic to help?

I have rebuilt heads before on american V8's, and if you have the tools, everything on the head is already done (valves seated with springs), then it is a couple of days to complete. If you need to re-grind the valves to seat them, replace springs & seals, if you have an overhead cam, I would leave this to a pro...

Some things that can go wrong...
1) Valves are not seated correctly, car won't start

2) Springs are adjusted too tight, and you grind the pushrods or the camshaft or break a valve

3) Heat is not seated correctly and leaks (or cracks) due to warping

4) Valve is not seated correctly and the cylinder crashes into the valve (destroying both valve and piston and maybe cylinder sleeve as well)

My advice... Have a pro do it. It will only take a day, you will have a warranty for the work, and you know you are not reponsible for anything that could go wrong...

Hi there boston kevin, I am currently working on my friend's Marshall Engines cylinder head and having a difficulty on that. I will thy this procedure that you gave and hopefully this will be the answer to our problem.

You're posting in the forum for 4th generation 4Runners (2003+). Some of us may have older trucks with the 22re motors, but you'll likely be much better served asking in the "Classic T4R" forum instead.

A mod may be able to move the thread for you.
