Re: 440 oil leak

[Scott Preston <penstarperformance@xxxxxxxxx>]

First find out about the oil and it it,s a high volume or high pressure pump,and you can then adjust the oil pressure relief  spring by shorting it by 1 coil,and then retry it.When my motors are running warm,normal temp at idle,they run at 20-30PSI and go to 60-70 at highway speed.You can also just get a old oil pump spring and install that to try it too,mrmopartech

I have a 440 that just broke a lose and started leaking oil at rear of engine. I thought it was rear main seal leak and had it replaced. Mechanic said the old seal looked fine, had silicon(black). It held about 15 miles and broke a lose again. I bought this car in Little Rock, Drove it 50 miles on other side of Fort Worth and back to southeastern NC at 3000 RPM (70 MPH) and it only used 2 quarts of oil.  It shows 70- 80 lbs oil pressure at idle and at 60 MPH. I've never had that much pressure on any motor I've had. Do you think it could be leaking at back of block at cam or lifter bore plugs and what do you think about replacing oil pump with less pressure? If you think the pressure is too high, what oil pump do you recommend. This problem is starting to get to be a real pain and expensive. Thanks.
