[QUOTE="Uluz2a6, post: 17295, member: 3941"] 👍 Was this project started due to jumping timing? If so you need to inspect camshaft "snouts" and make sure they didn't get moved/spun when engine was forced stopped. It's usually the intake shaft that moves and causes the headaches to begin. It's still possible to install the chain and start the engine. The ECM can overcome the variance, but will set the engine light due to the descrepency. 1st time I encountered it I had the head on and off 4 times and back the machine shop I used searching for issue. Finally got a cam off a running vehicle that was smoking to compare to and figured it out. I keep a new intake and exhaust cam in garage to compare each time I rebuild these engines to make sure.
