I have an e30 with an M42. I am planning to replace the engine's timing parts (guides, chain, gears, tensioner). After removing the old timing parts, I was hoping to swap in a late-model M42 timing case and its unique timing parts. Is it possible, however, to replace the timing case without removing the head or messing with either oil pans?
My first concern is that I will need to loosen the entire upper oil pan (after removing the lower oil pan) in order to access and remove the 5 bolts that screw into the base of the timing case. My second concern is not being able to adequately seal base of the new timing case without replacing the upper oil pan gasket. My third concern is that the new profile gasket may get squeezed and damaged during installation because the head is still on the engine. (BTW, big thanks to Balleristic31, bmwman91, and many others on here for their invaluable advice on the late-model M42 timing-case topic).
