View Full Version : Supercharger lock up

Last night I heard a clacking noise coming from my engine. I loosened the blower belt and spun the blower by hand and did not notice any problems. I thought the problem was a stuck lifter. Tonight I ran the engine a little more and then the blower locked up. I had cleaned the blower and it did not have any play in the shaft. Why did this happen?

How's the oil?

I would say it is probably your blower snout bearings. My car had the same problem and the blower started to lock up while i was driving. I swapped the blower snout out with one of my spares and the problem went away.

I checked my oil and it was filled up to the bottom of the plug. I will remove the snout and check that out but in the mean time I have another blower that I will install.
