When to worry about engine noises?

MRGTX said
I was able to take the car for a drive today and once fully warmed up, I noticed that when steady cruising at 50mph (2500 rpm) the engine made just about 43psi. When hot (200+F water temp), oil pressure dropped to 15ish at idle. Now I’m pretty worried about this.

So I will give BPE another call tomorrow or soon thereafter but If damage has already been done, would an oil analysis prove this? I saved a sample of my break-in oil and I can certainly collect some from the current oil as well.

The engine still runs great and pulls hard.

I'm not tryin to be a dillhole, but what all kinda diagnosis have you actually done? Your first post was last Wednesday and here we are 5 pages later and I see no diagnosis or verification. We're trying to help here......you did ask, after all. Try another manual pressure gauge.
