worst question ever!!

Re: worst question ever!!

stock turbo should bring about 1 bar.
check/clean the iac and also check for vacuum leaks. I would perform a leak-down test to make shure it´s the headgasket.

Re: worst question ever!!

I presume that a gasket is blown :i haved an oil service like last week and there's a lot of white emulsion inside the valve cover when i took off the cap saturday
the motor is running bad aswell(like it's running on 4 or 5 cylindres)and still lack of power,by the way,the turbo press is around 0.4 bars...i don't think this is normal service pressure?
And thanks for the tip jjorgensen :tup:

I agree, about 1 bar on the stock tune... also, I think emulsion inside the valve cover would be more of an indication of excess crankcase pressure, ie bad rings. Have you run a compression check on it?

Awright,but if there's a creamy emulsion in the valve cover,isn't that a sign of water is mixed in the oil?
I will perform a compression test,before taking off the heads anyway,i'm running on 98 oct pump gas,can that be a problem?
By the way:the truck totalises almost 30K miles...

not necessarily... that is a possible cause, but most likely you would have noticed a leak elsewhere if that was the case... it could also be from fuel / exhaust bubbling up through the valley.
Surprised you're having these kind of problems on a 30K truck .. do you know the history at all?

Oh, and 98 should be no problem :tup:

Re: worst question ever!!

okay,then i'll go for some rings !The truck was driven hard,even with a cold engine
So i'm gonna have a bad time on this one...thanks a lot for your help :tup:
