Primerdimer Posted December 30, 2019 Report Share Posted December 30, 2019 I’ve got a 521 with a stock L16. For the last month or so I’ve been having this clacking noise coming from the front of the engine (especially when the engine is cold on a cold day) which led me to believe that I probably needed swap out the timing chain, tensioner and guides... So here I am today, have the pan all dropped, valve cover off, and cant really see any signs that anything should be changed. The chain seems tight (I guess? Not sure how to check it actually), guides don’t seem worn, and the notch seems lined up just to the right of the cam... The advice I’m looking for is advice on what to do from here? If it is not stretched and in good condition, is it worth taking the cover off and water pump when they have non-leaky seals as of now? Or should I just swap it all out since I’m here already? And what are some things to look for to tell me whether this chain is good/bad? Thanks a lot! Quote Link to comment
