Dead Turbo? Exhaust Leak?

[eXc]

Hey Guys,

89 GTST.

I am worried my turbo is on it's way out. I only got the car from japan on Saturday, so I haven't even had it a week yet.

The turbo( or so I think) has had a small whistle in it that increases as you build boost. The whistle has gradually gotten louder over the past few days. I have searched and it seems that most people think the turbo is about to throw the wheel, or it's an exhuast leak.

I also have idleing problems -> http://www.skylinesaustralia.com/forums/sh...548#post1265548 <- don't know if it would be related or not?

What is my best plan of attack? How can I find an exhuast leak? Should I pull the turbo out and check it? What do I look for?

Anyone have a step by step guide to getting the turbo out the quickest/easiest way? Otherwise I will just work it out myself I guess!

Thanks guys

Chris

I had the same prob and found that it was the gasket between the turbo and manifold. You can pick them up for $10 but it is a prick to replace.

To check, When your car is cool. Start her up and feel around the turbo for air poping out(you may need to take the turbo guard off for this) and also look for carbon build up on the inside of the guard.

Thanks

what about using soapy water to find the leak? can you do that?

also check the turbo's mounting bolts

Hey guys,

It was the BOV! It blew part of the gasket away (had to take it off to see) so it was a boost leak...it's now back to the way it was when I got it (which is still there, but only a little)

I am guessing it will be totally fixed when I get the replacement pipe to ditch the BOV. Dam ricey Blitz BOV...haha

Cheers Guys
