2012 Chevy Traverse - 3.6 VVT High Feature/Interference engine
So, this is the second time in a year I've been in this engine to replace the timing chain, but that's what the mechanic swears is wrong with it (misfires like crazy still after brand new plugs and coils). I'm just not seeing the obvious signs of damage/wear like I did the first time, but one thing is bugging me. When I put the last chain on (secondary, right side), the colored link is just off from the tooth of the Exhaust cam phaser. I can rotate the phaser clockwise slightly, and line up the chain. As soon as I let loose of the wrench, it slips and the phaser returns to where it was (I'm assuming some type of tensioner inside). I was able to hold the chain in place until I installed the rest of the hardware, so I called it good. This time around, I'm second guessing...is that abnormal? Could it be contributing to my problems? I'm afraid to put this back together again just to need to pull it right back apart because I didn't fix the problem. Anyone run into this before? Am I just overthinking this? Thanks for any help
Both times. First time I replaced everything with the Cloyes VVT kit so new cam phasers, new chains, new tensioners, new gears, new gaskets. This time, I just did the AC Delco kit with chain and tensioners. And to be clear, once I hold the chain in place, and install the guides and tensioners to prevent the chain from moving, the sprocket stays put. But I know that the chain is preventing the sprocket from snapping back to where it wants to, and I can't help but wonder if that adjustment is somehow throwing off the timing once the engine is running. Buy I don't know enough about that to say for sure.

I admire you choice in Cloyes Timing Chains, They are the best chains ever made. Your motor is running good or not so?

I am having the same issue with the right bank of an 06 Cadillac SRX. I have to take a wrench on both cams on the right side and adjust/hold the right to the right and the left to the left to get the marks to line up. If it slips off the chain jumps like crazy. This is the second set of chains in 4k miles I'm trying to put one & can't help but think this is causing the issue. I'm using Melling chain complete kit w/ Melling oil pump & water pump. Did you ever get an answer to your problem?
