i sold a m37 (rough ) he got it running and we ended up swapping some old car shells and some money and i got it back.. ( ya i really needed it )... he said make sure i use a zink additive in the oil... never heard of such a thing.. he said it helps the cam lobs... and why we are on that question my other m37 needs an oil change .. what type grade oil do most people use... this engine hasn't been apart that i know of but runs well.
