I've replaced my turbo and its still having problems!!!

[kevingmorales]

Hello, i have a gst turbo 95,and i have a t25 on my car, and i've been having problems with my car, its blowing smoke out of the exhaust and i think i have exhaust leak, ### i see smoke coming out around the exhaust manifold on a count of i have 2 broken studs flushed in the head, ive recently been told in mitsubishi that the smoke could be cause by worn valve seal stems or somthing like that, and after they replaced the seals, they told me it could be the turbo,well its a 150000 mile car and the person that had the car before me didn't do any tune ups to the car so i have his problem now, so i've finally installed a 15000 mile turbo on my car and i took it around the block, it didn't spool all the way and i smoking worse the a freaking chimeny, i've done everything that the dealer told me and had help on dsmtalk,dsmtuners,and htown-dsm and no luck can you guys tell me the probable cause of the nightmare?

Sorry about the essay!

Hey everyone, if i have air passing through my dipstick does that mean that my piston rings are bad?and may be causing the problem?

Bad rings will cause excessive crank case pressure. There is one sure fire way to find out if it’s the rings or a cracked head is your problem is a leak down test. But I am sure that if the mech that did the valve seals at mitsu took the head off to do the valve seals he would have looked at the condition of the head for signs of crack’s or any major problems. Unless he changed the seals with the head on using compressed air or a nylon rope in the combustion chamber but I hope for the cash you shelled out he did it the proper way. Just do the leak test to find out if its either of those. When you had the compression test done what were your numbers?

Whoa, whoa, whoa... calm down. I was agreeing with you and at the same time putting in my 2 cents.... my last post wasn't directed towards you. The point of it was that the OP'r has already been suggested everything under the sun for his diagnosis, but is claiming that that's not the problem. The OP'r has basically said that it's impossible for the cause to be valve seals because he just changed them; that it's impossible for it to be the rings, because his leakdown test came back perfect; that it's impossible for it to be the turbo because he just replaced it with a perfectly good one with only 15,000 miles on it and that it isn't possible his friend sold him one that was already going out. That only leaves one other thing... the guide seals (which, like you, i HIGHLY DOUBT is the reason... as I stated earlier). So, unless the OP'r would like to start listening to our advice, and realize that just because you've checked/fixed something once doesn't mean it's fixed,it's impossible for us to help him.

I suggested the turbo, because that is most likely the case with the amount of smoke that's reported to have been coming out. It's still possible that smoke from a blown turbo can exit via the exhaust manifold. Smoke rises, and there's nothing keeping the smoke from rising back up and exiting the manifold if the manifold has a leak. It's also possible that valve seal replacement was done improperly, but it's been my expieriance that with that much smoke and under the conditions that it's smoking, it's the turbo. Either way, the OP'r will never figure out the problem if he doesn't start listening to our suggestions.

EDIT: My apologies... he stated that he had a compression test done and it checked out fine... not a leakdown. To the OP: Get a leakdown test done if your positive that it's not your turbo. Just make sure that the shop knows the difference between a leakdown and a compression test, some shops don't. It won't cost you more then 1 hours worth of shop time.

I apologize, I misinterpreted how you were phrasing/directing the post.

Hey man I know its a little far but.....I know a guy in San Antonio Tx that really know's his DSM's. He has his own shop and only works on DSM's.....I know for a fact he can figure out what is up with your car. If your interested I can get you his # and directions.

Carlos.

i see smoke coming out around the exhaust manifold on a count of i have 2 broken studs flushed in the head,

That will cause horrible spool right there. You're loosing all of the pressure that should be spooling your turbo. The same thing happened to me when the exhaust manifold-to-turbo gasket burned through on my car. It could also cause the oxygen sensor to read lean, causing the car to run rich, blowing black smoke. Ask me how I know. Boost leaks and exhaust leaks FTMFL.

Other than that, good luck with that burning oil problem.

Not a problem. After re-reading it, I can see how you would think it's directed towards you.

Hey guys i decide to drive my car the way it is, and for some reason when i drive slow,the car doesn't smoke at all but i do smell exhaust fumes.It doesn't smoke under idle or soft acceleration,it smokes only at wide open throttle,so what could the problem be right there?
