Hi guys,
I'm in process of getting a 2010 supercharged RRS. Read some posts as well youtube videos that for 5.0 engine, the timing chain guides will surely be worn out and potentially blown up the engine by causing all valves/pistons etc gone.

Since as a precaution measurement, it's also expensive to replace the guides. Is there any way to detect it in early stage?

Well the engine clicking noise during idle is an indicator. And I heard people could also find cam position sensor error when they scan the codes.

Just wondering if I do quarterly fault code scan then I should be able to detect any early stage of timing chain guides/tensioner fail?

Cheers
Tom

Some are fortunate and the tensioner assembly was replaced under warranty
Others are less lucky and the assembly starts rattling for months before it lets go
Some like me fall into a barrel of nipples and come out sucking my thumb, and the whole thing grenades in 30 seconds with no warning.
If it was me I would get it done and be done with it.

If you Google LTB00474 should bring up some info on the subject..

Cheers
Col
