Appreciate the input, gentlemen! The vehicle in question did not work out (selling dealer objected to an independent PPI; a huge red flag in my opinion) and therefore my search for a perfect L3/L4 continues. Thanks again!
Thanks, Ryan, this definitely makes sense. I feel the new steel button is a primary solution to the issue, with revised tensioner geometry. Cleaner oil will definitely help the tensioners to operate optimally, I just wish there was a consensus on how long the updated guides last.
Correct me if I’m wrong but the chain guide issue was due to the metallurgy defect on the guide itself where the tensioner would, in time, dent the spot in far enough that it would no longer supply necessary tension to the guide and the chain. Upgraded part had a different metal compound for the...
Thanks, DJ. That’s exactly what I’ve heard from the L405 crowd: the final iteration of tensioners that don’t wear out guides came out after 2015 MY, so I guess it’s a safe bet anything that anything older than that, original or replaced, is a potential failure point.
Thanks, Ryan. The car in question had 5k mi intervals throughout most of its life. Didn’t help much with the first cycle of tensioners, hopefully the improved version lasts longer.
Searched in the forum but could not get a definitive answer. If timing chain tensioners/guides/chains were replaced with redisigned components, what is the average life expectancy of these new items? There’s an 2010 LR4 for sale locally that had all these done at 60k mi by the dealer and is now...
