Okay, I took my ride to the shop, and had some tests done on it. They stated that it may be a problem with the inercooler or the wastegates may be jamed open- Meaning on pressure???? If that's the case, is that somthing that I can do myself?- He want's $500 us to pull off the inercoolers to check the wastegates. Does that sound right?

 

I would favor the help.

 

Thx

Pull the intercoolers off for $500 ?

ehrm..that doesn't sound right.

 

There are easier ways to check to see if the wastegates/actuators are still working, eg:

Remove the big rubber intake hoses..see picture below (don't mind the yellow arrows)

Pull the vacuum hose to the actuator ..there is one on driver-side and one on the passenger-side

Below the one on the driver-side is shown (yellow circle)

this is where the hose is attached (top yellow arrow)

I'm not sure if you're unsing boost-jets, but if so, you'll have to remove the jets out of the hose(s) first.

Next thing is to put the hose under 1 bar of pressure (using a small air-compressor).

 

It might be a bit difficult to see but you should watch the small bars that run from the actuator to the wastegate.(which are attached on the turbo)

They should move once you put pressure on the hose...if you listen carefully you can also hear the wastegate open (and close)

If nothing happens there is something wrong with either the actuator, wastegate (or maybe even the stock boost-solenoid) of that particular turbo.

 

Hope this helps.

BTW: here's a nice way to check whether your turbo's are still working

Thx for the help guys, but here's what I ran into when I took my intake hoses off.

 

OIL! there was oil in both hoses on the driver side (left side driver). So I went ahead and pulled of my bumper and removed both my intercoolers. Left side intercooler had oil it as well. It doesn't seem to burning after the turbo. (Smoking) So I took it to another shop to see what he thought it might be, but He couldn't tell, nor could we get to the turbo to see if it's jammed, any of you guys have an idea why my intercooler and hoses have oil it?

 

Lavone.

I have this problem too but the car runs fine.

Sometimes when i've really been thrashing it and let the engine idle for a few minutes to cool I get clouds of oil smoke from the back of the engine. Never knew what it was until I took the lower left big pipe off (intercooler?) to fit my boost controller and I found oil in it.

Is this the turbo oil seal that's gone & if so how much to fix?

Will this get worse and kill the turbo/destroy the intercooler or can it be cleaned out?

 

Oil in those pipes means you have leaking turbo-seals.

If it's just a little don't worry about it (yet), lots of oil is not good.

 

If you want to know if your turbo's are still working (aka blowing) try Jerry's trick:

So, even if I have a bad seal, My turbos should still spool up by doing this test (even thou I don't get anything now- boost)?

yes, I also have leaking seals, but my turbo's still work very well (knock on wood)

Well, that's good to hear. Just one more question. How mUch to get it fix and or is somthing that I can do with a friend or two?

Droop - if you and your friends (supplied with many cases of beer I hope wink.gif) can either get the turbo off without pulling the engine, or can pull the engine, then you can do that part yourself..

 

Reconning a turbo isn't a DIY job (unless you are very gifted with the right machinery) because the shaft & blades need balancing to a *very* fine tolerance..

I'd expect that part of the job to cost about $600 for both turbo's (at a rough guesstimate)..

 

If that is what you were asking smile.gif

 

------------------

Az

I'd already converted the UK £ into US $ for ya smile.gif so yeah 600US$ I'd guess.. (I think it's somewhere around 200UKP per turbo you see - depending where you go!)...

 

Could be very wrong - last turbo I looked at getting reconditioned was a T2 unit from a GT Turbo.. £100-150 to recon up to a hybrid..

I can get my turbos rebuilt for $200 usd Each. And I can get someone to pull the motor for $240. usd (8hrs at $30.00) Talk about a deal, he'll even pull the motor in my gurage =)

Oh yeah, and what does he charge to put it back. $2000 ???? wink.gif

Doh, Didn't even think about that.! =(
