My TII has 131,xxx miles on the engine, so I'm considering a rebuild in the future. My question is, should I wait till this engine pops, and then rebuild, or do it before, and continue modding till then?

I figure the two most likely things to happen would be a blown Apex or other seal, or end up overheating the engine (not as likely). What kind of damage would I see when an Apex goes, are the bits and pieces going to gouge everything up? how about pieces ending up in the Turbo? how about the other seals? water, side ect? How do I know when they go, what kind of problems do they cause?

And overheating, can an engine overheat a little? Is it possible to get just a little damage, and what kind of damage am I looking at (Just covering my bases, I never let the tempature creep up too high)

Thanks for your help, just trying to weigh my options.

Rebuild at your convienance, not the engines. You may end up with more salvageble/reusable parts that way. **** an APEX SEAL and you will lose a housing at the minumum.

How many parts can I expect to reuse, and still get reliable performance? I don't need an entirely new engine, as long as it gives me good compression, and I can expect it to last.

Could normal wear and tear be the difference between good housings, and ones that need to replaced?

So, I want to get it rebuilt before I blow an Apex, so I'll keep the boost resonable. What about other seals? anything I should watch out for?

What you'll need is a gasket set, complete set of 2mm 2 piece apex seals & springs, side seals & springs, you may wanna order a few spare corner seals because if your not careful those will break with ease, get all new corner seal plugs, you can reuse the springs for the corner seals...just make sure they have enough spring(you can always bend them a little to add spring). Get new oil O-rings (you can reuse the metal rings). Theres a few more things you may wanna get, but I'm runnin out of break time, so somebody correct me if I am wrong and add whatever else there is. Oh yeah, order the rebuild video, I think Atkinsrotary.com has one.
Good luck!

IMHO, don't rebuild until you need it - "if it ain't broke, don't fix it". A rebuild, especially if you've never done it before, is a LONG, complicated process, and there's lots that you can mess up. I wouldn't go out and *try* to blow your motor, but just wait until you need to do it.

The only thing you'd probably save yourself doing it now is a rotor housing - big deal. It's not worth the trouble to save a rotor housing that's probably out of spec anyhow.

I think you missed my point Dale, gather the parts and do it at your convienance, don't wait untile the engine blows and you HAVE to rebuild it. The thrashing searching for parts etc. A little pre-planning Goes a looong way. JOhn

I agree with banzai

when mine went i lost the housing, the rotor, and the turbo-the turbine looked like someone chewed on it. still, you'd probably need a new turbo anyway after so many miles so you may wan't to wait. but if you decide to rebuild, make sure you take the e-shaft bolt of while the engine is in the car so you have something to pull against. you'll probably need like a nine foot cheater bar to do it. thats why my old engine has been sitting in bags on my carport, i can't get the damn bolt off.
