I have the engine ready to pull. What else should I do while it's out ofthe car? Besides gaskets &coolant lines.
You think new rings? it has 180k on it.

Anybody know where I can buy some high performance head gaskets? (I'll post in the market place too)
thanx
Sean

Make sure to replace the ones at the Turbo, as These are a true pain in the butt to replace once back in the car.....:banghead:

Voice of experience talking.......:dead:

Yeah,
I figure at 180k the rings should be replaced.

Is it ok to use a scotch brite pad to cean the top of the piston and cylinder walls?
I used to do that with my dirtbike. Is it ok for a car?

scotch brite does it all! so does wd-40.
do all your front, cam, and oil pump seals while youre at it.
do you have the turbo gaskets? if you have to re-use use hi-temp copper silicone sealant, use on new gaskets too.

replace the rubber hose from the turbo to the intake. we just did a whole gasket set on a turbo motor just to have that hose blow out!

Well, it seems like this is getting too expensive so, I'm just going to inspect everythin and replace what's going bad. I have two cars I'm putting money into an I don't want to spend more on this one.(not right now, anyway)
Mainly I'll do all the seals and hoses.

Thanks for yor help.:headbang:

aside from valve grinds and such, at least do the oil pump seal and cam/front crank seal. all are accessible by doing a timing belt job. about 25-50 bucks in seals will do the trick!

the rear seal should be done if the motor is already out of the car. you will kick yourself if it springs a leak by ignoring it!

If you arent going to do everything moosens suggested I would at least get the valves reseated. Shouldnt need any fancy grinds. Get the heads tested too. Shouldnt be more then $100 for both jobs on both heads at a machine shop.

You are right though it ads up fast at the machine shop :( I spent $1600 on my EA82 when she was rebuilt. Biggest expense was a new head and labor.
