newly rebuilt 1275 engine in 1964 Sprite
at idle fully warmed, it drips from the rear main every 5 seconds.
oil: 20w50
oil pressure @ 1000 RPM: 40lbs
Am I overwelming the rear main with too much oil and causing it to come out the back instead of beaing able to drain inward through the lip and holes back into the pan?
When I built the engine I did stretch the oil pressure bypass spring out a bit.... maybe a bit too much?
The engine does not have any sort of PCV system. the breather on the timing cover is just vented to atmosphere with a little filter on it.
Thoughts? What is the oil pressure supposed to be fully warmed at 1000 rpm?
