Re: Oil pressure question
I was thinking amount of oil. Or, drain back issue. Returns blocked off? Personally, I would try adding a quart.

Re: Oil pressure question
I like -3 for pressure gauges. It's more responsive than -4 due to the reduced volume in the line. If using a Racepak, why not go total electric and use a transducer?

Re: Oil pressure question
I had an issue like this once and it was the distributor body not sealing.

Re: Oil pressure question
Cam bearings are King's but I don't know part number. The pan is a 7 quart Moroso which is basically a stock pan with a deeper sump, nothing special. I run 6 quarts of Penn 10-30. It's possible that I have the pickup to close to the pan. I recently read a post that said it should be about 1/2" and I've always put mine at 1/4 to 3/8.

My last oil analysis was the last 26 runs from 2017 and that oil sat in the car over the 2017 winter. I forgot to send it in until a few weeks ago and when I got it back it showed 5% fuel dilution. My only explanation for that is a couple start ups in pretty cold weather over the winter with no choke and a very lean idle circuit. I just sent in a sample for the first 31 runs this year and if the dilution numbers are still bad I'm thinking that could be the issue. The oil is fresh now and if pressure doesn't improve, I'll add a quart and see what happens. |

Re: Oil pressure question
I used to run a windage tray but after hearing many many opinions on the disadvantage/advantage of using this type, that type or none, I decided to not run one. The pan has the 2 layer sheet metal tray spot welded in just like the factory pans did. So that's all I have in it. Pressure stays up after the stripe but I don't run big numbers and ease off the throttle so there's not a lot of negative G's.

Re: Oil pressure question
OK, I'm going to step right into the line of fire here, and ask what's so bad about the oil pressure figures you're seeing? If you've got enough pressure, and more important, volume to keep everything lubricated (i.e. you're not burning cam bearings, pushrod tips or rocker arms), why are you worried? Ask the majority of Stock and Super Stock guys what kind of pressures they see from the starting line to the traps and I think you'll relax. I haven't seen 50 psi for decades, at any time.
