So crank bolt was/is fine, and I already ran a compression test (all 4 around 115 lbs). Also, the first cyl. was at TDC when expected on the crank by the timing mark. Not to mention the car starts, idles, and drives normally with the timing set where it is. I may pull the cam off the crank just to verify nothing weird is happening, but if that key had sheared or even distorted I'd have a TDC mark lined up on the crank but cyl 1 (or cyl 4 for setting the belt) wouldn't be at TDC unless I'm missing something...
I was hoping I had set the crank accessory pulley one bolt off and the marks were off but nope. That also wouldn't explain why the cap had to be at the max BTDC setting if it was just an issue of the mark on the lower cam...
So something somewhere is out of line, but I'm not even sure where to begin. I may order a new cap/rotor just to put that to bed, but it's not like the plastic suddenly re-molded itself 25 degrees off.
