My Official OM617 Toyota Pickup Repower Thread
Here's my swap thread.
My compression was fine, better than when I first started. I did use new heat shields when I installed the injectors.
I'm really starting to wonder if I have a rod coming loose. When under power and accelerating, no knocking. When coasting down, odd tapping noise. When just applying enough throttle to maintain speed, terrible racket.
I'm at the end of my patience for this motor, and going to hold off on spending any more money on it until after seeing the MBZ guru. Don't throw good money after bad and all that, if this motor is not long for this world I'd really rather dump that money into sourcing another motor.
