2001 Pontiac Sunfire Repair Question
What would cause the engine to sound like air is leaking from the engine in a pattern about ever second when idling? Ex. Psht, Psht, Psht
So sounds like a vacuum leak?You couldnt have installed a thread insert to repair the hole rather then replace the head?
I exchanged the head for a another re manufactured head. It turns out air was leaking around the spark plugs. It was a re manufacturing defect. Now I have a new problem. After another cylinder head install, the engine is ticking. The engine idles fine, accelerates fine, but creates a loud ticking noise. The ticking increases with acceleration and sometimes is not present until the car engine warms up. Have any ideas on the new problem.
Is the noise coming from under the valve cover?
I think so. It is really hard to tell. I had two mechanics tell me it sounds like a rocker arm but couldn't be certain.
DID YOU REMOVE, LABEL, AND RE-INSTALL ALL OF THE LITTLE GOODIES BACK IN PLACE, EXACTLY AS THEY CAME OUT.....TO INCLUDE PUSH RODS, ETC, ORIENTED IN THE DIRECTION THEY CAME OUT?
.......OR DID WE JUST SORTA PILE EVERYTHING TOGETHER AND ASSUME ONE PART WAS EXACTLY LIKE ANOTHER AND INTERCHANGEABLE?

Yes I took every thing out and assembled the rods into the same place. Although since these are not adjustable it shouldn't matter.
Get a long screw driver and see what see where the noise is coming from.You can put it up to your ear and touch different parts of the engine.
