Just completed a timing belt, balance belt, rollers, and water pump job on a 85.5 N/A 944. Everything went pretty well - used the flywheel lock. After belt installation and preliminary tensioning removed the flywheel lock, rotated the crankshaft two full revolutions by hand and finished tensioning. Completed the job and tried to start it and no cigar. The engine backfired mildly. Removed the front timing belt cover, manually reset the crankshaft to TDC and now the camshaft is off by about 80 degrees. For the life of me I cannot understand what happened. I do not think I bent any valves because I did not feel any excessive pressure when I rotated the crank manually after installing the belt. I removed the belt today and tried to rotate the camshaft manually and I feel more resistance than I am comfortable with about 10 degrees in each direction. What is my best out here - I would really prefer to not remove the head if possible. What about removing valve cover, loosening/removing camshaft and resetting the cam to the mark on the back of the camshaft housing cover. Please talk simple to me guys - this is the first time I have ever worked on a Porsche engine. Thanks
