*** EDIT: this was a dumb question. I answered it myself in post #4 in this thread
Greetings all-
I have a 2012 Liberty Jet 3.7L V6, 190k miles. Pulling heads to replace head gaskets.
I have the intake, valve covers, and timing cover removed. Looking at re-assembly instructions, the chains and sprockets have helpful markings to get the timing correct - plated links with yellow dots on the chains, yellow dots on the sprockets, L/R marks on cam sprockets, etc..
However, at present (before disassembly), none of the chain markings are where they're "supposed" to be. It's as if whoever was in there last didn't use the markings at all. The only markings that are "right" are the ones on the sprockets - they're all lined up / oriented perfectly when #1 is at TDC exhaust.
Is this something that might have happened at the factory? Or does it indicate that someone else has been in there before?
