oil pump failed
Well I will check it I was just saying! Haha
I’m just finishing up a 340 that had a high spot on the oil pump mounting pad. It wasn’t a big lip, but it was noticeable.
I didn’t catch it when I was installing the crank or I would have filed it off.
My thinking was it’s run like that for years, and I use a gasket under the pump so I was going to send it.
Then I got crossed up the compression ratio and had to remove all the pistons so I could mill a bit more of the dome off to get that right and I said screw it, pulled the cap and filed it down.
I feel much better and I glad I didn’t send it.
Anyway, my point is there was the possibility that had it let it go, even if the pump drive part of the housing had been in the main cap, it would have been ever so slightly cocked on the cap.
When you stick the pump drive in there you’ll have an alignment issue and it could cause problems.
I know it was running like that, because I know where that block came from. Knowing my luck, it would have bit me right in the *** and I’d be fixing it.
So I’m glad I missed on the CR and fixed it.
