Hi All,
I have a quick question, on the intake manifilod, front end just behind the alternator there is a brass 90 degree pipe screwed into the manifold. It has a screw with a spring in it, seems like some adjustment option. My 90 degree pipe just protrudes connects to nothing, I discovered this because it was sucking in air and it sounded like I had an alternator bearing problem. Removed the belts to help isolate the noise. I finally stuck my hand over it and sure enough it almost sucked in my finger.
I screwed it in as far as I could but is still has some vacuum.
What is the purpose of this?
I will post a picture tomorrow.
Thanks
MBP.
