OK, I installed the original chain set up, and installed all new oil lines. I also replaced the outer primary cover because the old one had vents in it for the belt system. The new primary cover has an extra hole at the bottom, where the old one had that hole only partially drilled out. The new cover has a pretty good leak that seems to be coming from that extra hole. How do I fix it?

 

primary drain hole?
Buy the oem magnetic plug

 

No. An extra bolt hole in the bottom rear of the outer cover itself.

 

I should have gotten a primary cover that did not have the 9th hole drilled all the way thru.

Too late now. Any ideas how to plug the unused 9th hole?

 

A cheap fix would to be to fill it with JB Weld
