ok im at a bit of a loss as to what the shop is telling me about my truck, they say i need a blow by test and if it comes back to high then i need to replace my turbo. so are thay saying my turbo might be producing to much psi or what are they telling me is wrong here?

 

I will call BS on that one.

A blowby test will let you know the condition of your pistons, rings, etc.

When you have too much PSI from your Turbo you take out headgaskets......

First things first, why did you take it to the shop? ( Symptoms, etc. )

 

ok im feeling a little better then cuz thats what i thought and i thought i had a pritty good grasp on this stuff. i took it in for some electrical thats fixed now and oil leaking out of the breather tube.
