[QUOTE="swshawaii, post: 1041633, member: 67547"] Not to stray from the discussion above, but here's a common failure point for the REAR tensioner guide. Not an engineer, but looking at this pic believe metal reinforcement "may" have prevented failure. Interesting thread linked below, good reading. [URL unfurl="true"]https://www.explorerforum.com/forums/threads/why-the-plastic-guides-on-timing-chain.399121/post-3768685[/URL] EDIT- added "GUIDE" to avoid confusion. (Not hydraulic tensioners) [USER=74901]@DILLARD000[/USER] Thanks for adding the REAR "plastic tensioner guide from hell" pic in the following post. (#9) Here's another. Oil looks VERY sludgy. Instead of low maintenance, call this NO maintenance. Pathetic. [ATTACH type="full" alt="RCasset.jpg"]1838[/ATTACH] And another from this interesting thread.
