well i have a problem the other day i put a 3 piece manifold on and 4inch magnaflow exhaust. start it up sounds good. drive it there is a squeal when the turbo start to spool up. and also sqeals when i pull exhaust brake on.. seems like it is coming from the wastegate actuator. any suggestions????

 

High Pitched Squeal?

 

yep i know its weird

 

is manifold leaking

 

dont think it is

 

I would check the manifold gasket really closely. Also try the joint at the turbo. High pitch squeal is usually exhaust gas going past a gasket.

 

Intercooler boot may be unseated/ not tightly connected.

 

well fixed the squeal. manifold leaking tightened up more and squeal gone still a small leak i have to go out all bold and retighten.

 

man im glad you found it
