Glad you're back at it.
Thanks! Yep, there's something special about it. In my case, it's owning it for 57 years and part of a lot of life.

Jim,
I’ll bet you’ve got some leakage in the oil filter mounting bracket, or perhaps the pressure sending unit. Good luck to you on finding the source!

Ironically, I was just digging around there myself on mine today… that’s why I thought of it. After installing the Doug’s Headers, I cannot get the standard sized oil filter in there, so trying to decide which route to go to be able to get this car fired up again!

Try this:

Or perhaps the smaller diameter 1979 Cadillac filter mentioned in that thread.

Thanks! I'll check that. I have the factory original oil filter mounting and the RA/HO Longbranch adapter with the multiple gaskets to angle the filter. (Never touched since the factory assembled it.)

Put in a functional windscreen washer setup on the 71. Of the dozen GM cars I had that used this wiper pump setup, I think maybe one actually worked correctly.

I used a below tank pump (self priming) from a 1975-79 Firebird supplied by this forum's sponsor. It works quite well.

This can also be used on a stock reservoir if a 9/16" hole is drilled in the bottom. A 9/16-12 nut with sealant mounts the pump. Power can be run to the pump, and the washer switch grounding feed is used to trigger operation. You may need to adapt hose size.
