So I am getting ready to pull the cams and girdle on my drivers side bank 4-6 on my '03 3.2. #5 cylinder has no compression and I suspect a busted valve spring. I have been on the internet more than a porn-watching teenager sourcing as much information as I can prior to diving in. (Also have the Bentley and 101 projects)
Lots of information out there on 5 chain motors...not as much on 3 chains. Some stories about loosing time due to chains jumping teeth have me suffering from paralysis by analysis. However, these seem to be related to IMS change projects.
I am only removing cams and girdle and hopefully changing out a valve spring. I will be following procedure I have read about by:
-locking/pinning the crank at TDC
-locking both the cams prior to removal of cam cover using 9686 tool
-marking the chain and sprockets in several locations
-loosening tensioner and removing chain and cams
-doing the spring job (fingers crossed that is what it is)
-reassembling everything back to the way it was prior to removing everything thanks to my marking of the cam and chains
-removing pins and locks
-buttoning everything up and driving off into the sunset.
Is there any reason I cant proceed besides fear?
I have been into other motors and done similar work but I am getting the impression that the flat6 has special physics defying properties not yet understood by modern science...
