changed out the heads on my 302 ford. Runs good but oil pressure is now really low. Checked with a second gauge, same reading as the old one. What is going on?
Are you using a mechanical or electric gauge?Ithink you may have gotten a tiny piece of crud in the pressure port.There are no pressure p***ages in the heads except for pushrods.You also could have gotten alot of **** down in the pan and it is blocking the pickup.
Try a different (new) oil filter (you could have gotten a bad one), provided you didn't get a lot of **** in the pan, and pick up tube like 65comet suggested.
