Help,
I've got this 1.8t 145k engine has a rattle on the top behind the engine and rpm sluggish. Some times throws intermittent coe P0011 for the timing over advanced. The noise comes back also on idle when vehicle gets to operating temperature. I took it to dealer they said they need to drop the pan and see what's going on. I did the work my self and replaced the pickup tube while I was there.





Everything looked good. I put 5w40 from dealer. Anyone know what might be the issue here? Could the chain tensioner be failing internally? I popped the valve cover put no damage seen. Noise is very annoying and getting worse. Thanks for viewing.

Sounds to me like a bad timing chain tensioner.

That's what i'm thinking now! dealer said they would start with lowering pan and then replace tensioner. I'm going to get the part, I will need another tensioner tool for the one installed?

Prospeeder

should come with one, make sure to keep it too. Shop around for one, dealer is going to want way to much

The tool that comes with it I can unscrew it andb u se it on old one?

Prospeeder

Yes sir. You will need to remove the intake camshaft to do it, no need to mess with timing belt stuff it you dont have to. remember, 16 links arrow to arrowish.

Also the chain wore out the plastic part of the tensioner like 2 inches! Hopefully the pictures shows u the proof.

some of these show too much liquid gasket was used on the valve cover seals.

did you ever find out what caused the tensioner oil screen to collapse?
