3.6L - To replace or rebuild?
I'm trying to make a decision on the most time/cost effective move forward, and could use insight from someone who knows these engines. I just traded in my 2012 TDI for the buyback last week (missing her dearly). Prior to that I drove a friend's 2008 FSI and decided I would get a T1 or T2 after giving up the TDI. In searching I found a 2007 3.6L in excellent condition (for its age), but with a reported timing chain problem. That wasn't enough to scare me away because I got it for so cheap.
I also had just finished rebuilding the engine on my wife's Audi, so I was feeling in the mood for another rebuild. Prior to turning in the TDI, I had the pleasure of driving out and towing her replacement home 700 miles...great times! Back home and on the scanner - it cranks but won't start, and is throwing no codes or CEL. The timing chain diagnosis appears to be correct.
My friend told me that starting in 2008, the timing chain issues (stretched chain, tensioner and bolt problems) were solved on the T2 3.6's, but I have yet to confirm. If this is the case, I might consider option A of tracking down an 08 or 09 motor for quick swap if possible.
Otherwise, I'll resort to option B, pulling in the crane and start tearing it down. If the issues are the same across the board, I wouldn't install anything else without installing new timing components anyway.
Any insight or input would be greatly appreciated! Thanks guys/gals.
