I'm troubleshooting some blow back I'm getting on a new, never run, engine.
At Top Dead Center (ATDC) Cylinder---Intake-----------------Exhaust 1-----------CLOSED----------------CLOSED 2 3 4 Options – OPEN / CLOSED / OPENING / CLOSING Can anyone complete this chart for me? But I’m mostly interested in 3 and 4. If someone knows it, can they tell me if the 1and 3 valve positions are the same as 2 and 4 when the crank is 180deg out from TDC? Thanks! -JR- Soon to be driving his 914 |

There is a hole in the bottom of the transmission bell housing, there is a notch in the flywheel (not the front fan pully) that will line up in the hole in the bellhousing when the engine is 180. I do TDC on the top then turn the wheel (lock the other wheel with a jack under it) from underneath and line up the 180 mark. Repeat.
