There is a seal to seal the pan to the block. This seal goes out mostly do to lack of oil changes. Change oil then add a stop seal leak additive that closes off the leak with no harm to the engine. It works!

The glass will be the same but check where it attaches to the lift that may be different.

I would start with the Pickup Coil and the Crank Sensor.

The sensor is on the back side of engine at the lip of the oil pan put installed in the engine block.

1992 buick road master after you put a new battery it crank but wont start what is the problem

Could be a fuse, a relay... definitely something electrical. Now if you have dash lights coming on for no apparent reason, it's the ignition switch.

No. The engine won't run with a faulty crank sensor.

It is important to know the symptoms of a bad car part. The symptoms of a bad crank sensor is acceleration problems, engine sputtering and engine stalling.

Crank Pulley, crank sensor, ignition module, dirty maf sensors, clogged fuel filters.

By disassembling the engine. Not a DIY job.
