Thanks for posting this richard. I just replaced my timing chain, guides, tensioner and vvt solenoids in my 2014 equinox 2.4l ecotech and had noticed once I manually turned the crank 720 degrees to verify no interference that there was a tiny bit of slack exactly where you showed here. Everywhere else the chain was tight. When I fired the vehicle up I noticed an engine ticking (which was also there prior to installation, but I may be more sensitive to the sound now because of the install). I was paranoid I messed something up and this tiny bit of slack was the only thing I could think of that may of been wrong. This video eases my mind a bit about that and thank you again. Still gona have to dive deeper on to what this ticking sound could be. Oil is new and full. Never heard of these vehicles having lifter issues but im leaning towards that. Sound becomes more apparent once vehicle is at temp and rate of ticking increases on acceleration. I mean i guess it could be from my timing chain still but its more of a ticking and not a rattling type noise. Any thoughts?
It is more than difficult to diagnose a problem from afar. Turn the sprocket to your right clockwise just enough to take up that small amount of play between the two sprockets. The chain should now be tight everywhere. If there is play anywhere then you still have an issue.
I took my Valve Cover off on my 2004 Acura TSX to do a valve lash adjustment. When rotating manually, the timing lines and dots line up where the manual says it should, even after rotating multiple times. I noticed sometimes slack appears, but on the "right" side of the intake shaft. I don't have it happening under the guide up top. But, it is tight on the tensioner side. Safe to assume the chain is good?
Is it compulsory to change the guides too when changing your chain and tensioner? Or can you get away with not changing the guides? Thanks! Great vid by the way. Very informative
This helped a lot I’m used to belts not chains and when I rotate there’s no slack anywhere and the the tensioner slammes closed and then i continue to rotate and then there’s slack. And the. The tensioner Shiites forward. Just confused want to know if it’s fine. Great video
Sounds like you are ok, slack between the sprockets depends on where the cams are when you stop rotating, as you know the valves are spring loaded possibly causing the sprocket on the opposite of the tensioner to spring backward causing a little play between the two.
@@richardspaulding5035thanks just wanted clarification since I’m a belt guy 😅. It always meets together every time I rotate the crank to tdc. Also the tensioner runs off oil pressure. It tensions at first then it goes back. I’ve heard that when the cars on the tensioner will not shoot back because of the oil
I was under the impression that a chain should last the lifetime of the vehicle and did not have a replacement interval like a belt. Regular oil changes with a high quality oil are key.
I want to thank you very much for this question as I now realize I should have provided a better explanation in the video. In the days to come I am going to post a follow-up. Engines like the one in the video that are classified as an interference motor usually do have some sort of maintenance schedule for the chain. It may be just a simple inspection interval or a full replacement interval. This is because sever damage to the engine will occur should the chain on an interference motor fail. There usually is no such requirement on a noninterference motor (I think that is what you are referring to). As I mentioned in the video, I did not have access to the owner's manual. I am assuming this engine has a replacement interval because there is no removable inspection plate on the valve or timing cover. Thanks again as I always enjoy hearing from you.
I learned something about slack in timing chains today. Thanks for sharing your knowledge, Rick.
Thanks for watching i am glad you enjoyed the video
THANK YOU SO MUCH, the obvious camshaft kickback you just explained.... WHY DID I NOT REALIZE THAT LOL. thank you so much sir your awesome! hahaha.
An unscrupulous mechanic could sell a timing chain job anytime he wanted. LOL

It appears so from what you describe

Given the amount of work to get at the chain I would replace them needed or not, most kits come with guides and gaskets.

Do you like chains or belts better?
I would not buy a car with a belt
