I'll drive it someday
I posted a while ago that the oil pressure in my cheepo crate engine 350 runs extremely high. Idle pressure was on the order of 100 PSI and it was higher at speed. I attributed part of the issue to running high viscosity oil (15W40 Rotella) and part to running a filter mount without a bypass. I also have an HV oil pump on there which was necessitated by the oil pickup being welded on to the pump and this was the only pickup that I had that fit the pan.
I'll say up front that I know nothing about the engine other than it runs pretty well and is very gutless.
Over the weekend, I changed the oil for the first time since I put the engine in. There wasn't much mileage on the oil but there was a fair bit of time. Besides, I keep expecting the oil pressure gauge line to pop off and flood my compartment so wanted to solve the issue.
First off, I found a normal, bypass oil filter mount. Only tested it by pushing on the valve and having it give but is seems to be working correctly. Guess my memory isn’t what it once was. Could be that it never was and I don’t remember.
:confused2:
Second, I put in 5 quarts of 10W30. Started it up and immediately pegged the oil pressure gauge. I've not put more than a couple of miles on it since and the pressure does occasionally drop below "pegged" but it's still pretty high. I've not put a calibrated gauge on it, nor do I intend to.
The question is, besides robbing power from an already anemic engine and the possibility of a cockpit oil bath, is there any other potential harm to the engine?
