Hi, this is my first post and I am new to 6 cylinders. I need to know what is decent oil pressure for a 250 engine. I just got a 64 pickup which had sit for some time. Got it running today and I am getting a lot of blowby out of the breather and oil pressure was about 30 at startup and after warn up it dropped to around 22 . As the rpm goes up it will raise to 28 when hot. Is this normal or is my pressure too low? I know this would suck on a V8. Hope to change oil and run it some tomorrow to see if the blowby improves. Any info would be appreciated.
