2006 engine squeaking

hey guys, i havent been on here in a while cuz ive been so buzy with school but i come with a question...

my friend, her jeep is a 6cyl. 2006 auto. with ~40000 miles on it

on the passenger side on the engine practically in the middle of the block there is a circular cap perpendicular to the block with two T25 torx screws holding it down...it makes a squeaking/chirping noise anytime the engine is on it does get faster as the RPMs increase...

ive never seen this on my 2000 6cyl and cant even think of what it would be...

my question, what is it? and does anyone know what the squeaking is?

That sounds like the oil pump drive assembly / camshaft position sensor. The upper bushing on the shaft is a sealed unit & does not get any oil from the engine to lube it. That's the squeal you're hearing. There is a big discussion on Jeep forum about this problem. There is also a gear on the end of this shaft that turns it off the camshaft. This gear is prematurely wearing too. I replaced this whole assembly at 30,000 miles on my 06 6 cylinder. It wasn't making the noise yet that your talking about, but I found out about this problem early enough before mine got that bad. Hopefully hers has not worn the gear on the camshaft also. Get on the Jeep forum & enter a search for Chrysler is paying for a new camshaft. Its on the tj section & is 65 pages long very lengthy but very good info on this problem. Hope this helps.

you can take the assembly apart clean (i used a shotgun brush) and regrease and you will be fine. Total time is about 1.5 hours.

What did the dealer replace? Did they replace the oil pump drive. Glad you got it fixed for only $50.
