Yea I’m thinking of just taking the time off to just work on this. I would be very meticulous and slow in the procedure as it’s my first time even attempting something this big. I’m a quick learner and been watching these videos on the procedure countless times but you made it seem so much simpler than the videos explain. I would have to get through diagnosing the entire thing myself and then going from there. Should check valves be faulty if this engine should’ve gotten all the necessary timing upgrades? I’m kinda tryna prepare what I’m going to be doing when I get in there. I kinda want to order everything and return what I won’t use because I don’t want to continually remove the intake.Before buying the Endurance warranty, I would be very specific in asking whether the faulty camshaft adjusters, and any additional timing system repairs are covered, if there is no CEL. I bet the answer is no. I was quoted $10,000 for the full “Monty” by the dealer: all four cam adjusters, new timing chains, all new chain rails, new tensioners, four new camshafts (I believe).
I did the job myself. Only needed one new cam adjuster. I did replace the secondary chain tensioners, and my engine did not have the check valves installed, so I did check valves as well. I did the entire repair through the front covers only, with rear vacuum pump removal (bank 2) in order to access internal #60 torx at rear of camshaft. This enabled me to use a helper to counter hold during loosening and tightening procedures necessary to replace defective camshaft adjuster (bank2/intake) in my case. I did not remove the valve covers. Car is perfect now. No cold start rattle, idle is smooth, acceleration is fantastic , gas mileage is fantastic. Engine is absolutely still at idle. No codes.
Wanted to add this earlier but had to stop with the essay: I have also been using 89’ gas because it’s fr33 but since yesterday I have been using ‘93 again after the fresh oil change to see if this is gonna improve the start up noise and I can honestly say that there has been a drastic decrease of the rattle/stalling feeling In less than 24 hours. I don’t know if the use of ‘89 had an affect that bad but I’m gonna keep monitoring it everytime I start it the next few days.
But yea back to the drawing board. Im gonna just order some intake gaskets to replace once I lift it up so I can check the timing and then order the kit or cam adjuster depending on what I find
