MGB At what oil pressure do I need to dig into the engine?

as little as .0005" extra clearance can affect the oil pressure as much as 10 psi.

This, my friend, is why you build engines and I don't. :grin:

My plan now is just to keep an eye on things and keep driving. This engine really only needs to last 1 or two more years (less than 10k miles) before it's replaced so I'm just going to hope for the best, and keep gathering parts for the (supercharged) replacement.
 
My similar '69 MGB runs about the same pressures. Early in the year when it was hot and I was still running 5W/30 the hot cruising pressure was high 30s. I switched to 20W-50 and that brought it up. My idle pressure is about 20 psi. The one thing you want to look at in these engines is the lifters. They can get pretty beat up with time they can make a mess out of the cam. It's pretty easy to loosen a rocker arm, pull a push rod and then pull a tappet cover off and remove each lifter for inspection.
