Distributor ruined by blown motor? 91' 3vze
A question for all the high level yota experts, mechanics, and engineers: is it possible a distributor could be broken as a result of a blown motor?
I ask because my motor blew last year due to a blown crankshaft and I know the crankshaft position sensor is in the distributor and I wonder could it have been affected post detonation. I'm not familiar with how the CPS works especially being inside the distributor.

Probably not. And if I had said "yes," would you just replace the distributor?
The distributor is driven by the camshaft, and the NE and G coils in the distributor provide the signal to the ECM and igniter to fire the plugs. So you don't have a "crankshaft position sensor," but the position of the crankshaft could be inferred from the position of the cam. The FSM contains a procedure for checking the coils.
Of course, I don't really know what a "blown crankshaft" is. Bearing failure? Fracture? Fire?
