Can o' worms 90 degree oil filter adapter
There are different gaskets for each placement and if they are not in the right place, you get a leak. That's all I know. There's a diagram around here somewhere that shows how the gaskets install, but I never have luck with the search function. Fear not, it's not a difficult problem to fix, but I sympathize with you. I'm only 58, but as an machinist, alignment and suspension mechanic all my life, my body is slam wore out before its time.
