DO you guys have wear on the hole where the drive shaft for the water pump goes thur the timing cover? This is only on the top of the hole it seems to be gaulding up the top of the hole in the cover The shaft must be walking up some how under rpm. It as no leaks but little bit of Alum.is on the shaft. Thanks for relys.

 

I'm sure its a pretty common thing. As long as it aint leaking then I wouldnt worry about it.
