Can anyone tell me from the photo where the oil may be leakng from ? I have started to notice small spots on the driveway.

 

Thanks in advance !

Very hard to tell by that photo alone but could be rear main bearing seal, seal plate or oil pan.

Yep....looks like your starter bolts have started to leak.

When was the last time you changed the starter fluid?

Does the 2001's have the crank position sensor above the starter like the newer ones do.

I know on the GMT900's, oil leaking on the starter bolts is usually coming from the CPS above it.

I've got a '99 on the hoist right now and yep, sure enough the CPS is there above the starter.

What's all involved in changing this CPS out if that is where its leaking from ? Is it something that should be left up to a shop ? How much do these run in price ?

 

Thanks for the replies..

Yep, the CPS is a big culprit for the oil pattern you're seeing
