how do you know if a turbocharger is blown? even if it has no shaft play at all...could it be blown? could one of the symtoms be - not getting boost until 5500 - 6k and only geting 5psi at that...when the wastegate is fully chained shut

 

well im not a guru at this ----, but you know when their is oil everywhere, and if your turbo is burning your oil, and if their is oil in the compressor housing.

 

well i think i probably blew my rings anways...i guess i will just do a compression check

 

a compression check to see if your turbo is blown? you amaze me. no boost til 5k is usually cuz of a nice size turbo laggin a bit or a wg issue... solve it

 

Do a pressure test on your cold pipes to see if you have any boost leaks.

 

cold pipes? why not all the pipes, there could be a boost leak anywhere in his piping

 

When I refer to "cold pipes" i mean all pipes between the turbo and throttle body.

There could also be an exhaust leak of course.

 

learn how to refer to certain parts of the engine bay.... cold pipe is ic>throttle body, hot pipe is turbo>ic. you can't refer to ALL intercooler piping as cold pipes haha, then where would the hot pipes be? the exhaust and manifold?

 

Yes, I usually refer to intercooler piping as "cold pipes" and if I need to specify further I will say pre-IC or post-IC.

I then refer to "hot pipes" as the exhaust piping. I'll agree this could be confusing to some of you since the majority of you run manifolds with a flange and a turbo bolted up. However, those of us with a V6 or V8 that run a typical single turbo setup cannot do this (at least not if we want all cylinders to be pushing the turbo).

I'll try to remember your different terminology as to not confuse people next time.
