Alright this is a strange one but I'm getting a Squeaky Noise coming out from my engine, Now It doesn't happen all the time its at all types of random intervals. Its Not coming from the pully area IT sounds like its under the intake or Some where like that but its not a knock its A Squeak! Anyone have any sort of clue???? Thanks

 

I'd check real close at your tensioner pulley. Otherwise I can't really think of what could be squeaking internally.

 

Ok I don't Understand this, but I went and got gas and the Noise has stoped, Do injectors SqueaL?

 

I had a spun cam bearing do that, it made a squeeling sound in the center of the engine that would randomly come and go until it was so bad it siezed.

 

The idler/tensioner pulley bearings can do that..check those out ASAP... no sense in letting a $20 part leaving you stranded

 

Ok Noise 1 is gone but Now I'm getting a ticking from the passagers side of the engine under the valve cover... Its never been like that before, I just changed the oil a week ago, I made the change to synthetic after 55k.... Could that be it, should I change back?
