I feel like my tensioner is OK. I think that the chain just stretched so much that it was beyond the ability of the tensioner to take the slack up because the plunger was completely extended.
The spring that is in that tensioner is pretty healthy. It seems like it would be more than enough to keep the tension on the chain during startup while the engine is building oil pressure...that is if the chain is not already stretched too far.
I am still fighting with myself on whether to replace the cam phasers. Right now leaning toward not replacing them.
I think after I get this done I am going to do 2 things once I get it back together (providing it ever runs again!
1. Change oil at 3000 mile intervals. I tend to subscribe to the theory that carbon in the oil from blow-by is eating these chains up. From all I have read, boosted motors seem to have more blow-by because of the higher combustion chamber pressures.
2. I am also going to put a catch can on it. I have read the many pages of threads (read as arguments!) about catch cans. But, I think anything it can catch before it is ingested back into the motor is good.
