Pull up the text of the TSB that Umbertob posted and see which models and VINs were included.Is this about replacing the plastic timing chain tensioner with a metal one? If so why are they only issuing a TSB for normally aspirated cars?
I have a supercharged 2012 RRS, assuming the TSB wasn't already done, would I have a plastic tensioner that needs changing?
Sorry not finding it.Pull up the text of the TSB that Umbertob posted and see which models and VINs were included.
To clarify, LR did not use a "plastic" tensioner. There are two arched guides made from aluminum that are thrust against the timing chain via oil driven tensioners that have steel push rods or plungers. There are 2 issues at hand:Is this about replacing the plastic timing chain tensioner with a metal one?
And if needed - Here's a Post - from someone on this forum before this video came out describing these differences for both of these tensioners as well....SaturnV,
Excellent information and attached video.
Quite a design flaw instigated by Ford.
Thank you for your input.
So, am I correct in understanding that all 2013 models, irregardless of build date, have the update?Don't think these newer tensioners and blades were available until they determined that this timing noise was a common occurrence on
these newer 5.0 liter engines and had to be re-engineered and designed to prevent this failure and noise. Why some 2012 & 2013 already
have the newer tensioner/blades installed at the factory.
