When I was swapping my sensors from my e36 to the e30 M42 block the front one cracked on me
Please PM if you have one!
Thank You!!!

Pretty much all original ones by this time are cracked, fragile, falling apart, and pending failure.

If you have the engine in a state where it is easy to reach the sensors by all means replace them with new ones.

I spent the bulk of today pulling the intake manifold off my S52 and changing both sensors because #2 failed. They were the only sensors I didn't replace when I did the swap and I'll be damned if they didn't look OK.

Hey, I have a variety of known-good M42 sensors. PM me if you are still interested.
