P80 engine crankshaft diagram - where are pistons relative to the timing mark?

Post by abscate » Mon Jan 07, 2019 11:48 am

Im trying to free up a white block NA which has a stuck piston number 5.

Does anyone have an image or diagram of which piston is where during the crank pulley cycle?

Im hoping the piston is stuck mid stroke so I have a better shot of popping it free without breaking a ring.

Would it be helpful to measure the depth of each piston via the spark plug holes?

I like thin oil poured in cylinder for freeing stuck piston. Do you know if it had coolant in that cylinder or what?

No coolant use reported by PO and oil clean and non-milky. Piston not looking any cleaner than others

All signs point to no coolant in cylinder'

Im using a ATF acetone MMO mix in cylinder 5

I can't believe I didn't think to use Pooh sticks to measure piston position - apparently I am a Bear of Little Brain

Number 5 is stuck mid stroke - SWEET!!
