Have you checked the FPR?
Did you bend any valves? What did you do to fix it?Mine did the same thing, except I had 0 -30lbs of compression on the front cylinders. It ended up being the pin that holds the sprocket in place on the cam shaft fell out.
Don't want to hi-jack this thread, but yes it bent every valve. When I checked the timing by taking the cover off it appeared to be in time (just eyeballed it) and I didn't see the pin missing. By the time I took the motor out it was obvious what happened. It looks like the cam must have spun about 360deg. No piston damage, just some slight marks. To fix it I got a used head from a salvage yard from a low milage vin 9. I'v put on 5000 miles since with no problems.Did you bend any valves? What did you do to fix it?
