My 1989 GMC jimmy S-15 makes noise wen I press on the trotle sounds like it needs a valve job but it doesn't do it wen it's in park and just idles.I just got this truck so I dont know is this normal or any suggestion, I saw 2 other truks and they son the same.
Thanks Steph.

Are you sure it is coming from inside the engine? What does it sound like? I would try to remove the belt and listen and see if the noise is still there then you will know for sure if it is internal or not.
