Engine/Transmission (1994 - 1998) dying turbocharger?

[purdytj]

Greetings all,

Before I go to the repair shop, I'm wondering about your thoughts on this problem: I mash the throttle and it seems as if the turbo is spinning up, but the gauge is only showing about 10psi boost. The EGT gauge climbs quickly up to 10,000 degrees. The sound coming from under the hood is a "shwooshhhhhhhhhhhhhh" like a seriously leaking tire. The engine sounds and runs fine at idle when I look under the hood. I don't think I see any leaks but can't really see what is happening because it only happens when driving and the engine is under load.

Is my turbo dying? When I hear the "shhhhhhhhh" I cringe with the thought of how expensive this could be.

Sounds more like you have either a hole in your turbo piping and or intercooler, or a boot has slipped out of joint.

Check all joints from the turbo to the intake.

If you don't find anything visually wrong you can leak check it with soapy water and find an air leak.

You must mean 1,000 degrees... right?



I agree with Nyoest... sounds like something has come loose or broken and you have a boost leak.

found it!

Thanks! There is a disconnected hose at the intercooler. I found it when lying on the creeper - it couldn't be seen from above. I'll reconnect and give a test run later today. I'm sure that is it. See the pic.



I appreciate your help.

God bless the TDR!!!

Oops, yes, too many zeros on a Saturday morning.

Glad you found it. I was going to suggest for you to use the "ether test" that we have used on farm and construction equipment for years. Just get a can of starting fluid and with the engine running at idle, spray all of the joints,connections, hoses,etc. If the engine races up, you have found a leak.

This will work for the intercooler as well, just be sure NOT to spray it around or into the air cleaner or you could get false test results. . :-laf

That will do it everytime! Glad you got solved!

Either is ok maybe for the older engines but no way in he** I'd put it to a newer cr engine. Those expensive little solenoids on top of the expensive little injectors might not like the go juice.



To the op glad you got it sorted out. Happy motoring.

Yea there are safer chemicals that can be used... ... .....

For anyone reading this one, ether on the leak isn't a good idea especially if the intake heaters are cycling on and off. Your best bet is to make up the pressure adapter that fits on the turbo intake and has a air chuck on the other end, you then apply about 20 psi of air from an air compressor and look for the leak.

It's been written up in two issues of the TDR and has been discussed here before.
