8N oil pressure

[Wasgd4u]

48 at startup,30 to 35 when hot after an hour or more use,would this indicate an oil pump problem,has around 300hrs since rebuild?

I would suspect the gauge before the oil pump or maybe someone stretched the oil relief spring?

I see nothing wrong with your pressure..It will drop as the oil heats up..

Mine starts at 30 and drops to 10 or less..

Hot oil is thinner than cold oil and normal behavior is for oil pressure to drop a bit as the engine warms up. Your numbers are fine.

OK, I'll say it first, "30 - 35 when hot after an hour or more"....them is bragging rights.

As has been said, hot oil is suposed to be thinner than cold.

48 cold, 35 hot?

sounds almost like a new engine to me...

My 49 8n front mount starts at around 45 half hour later its around 5. I dont worry bout it been that way for the 4 yrs that i have owned it.

I wish any one of mine had that much,i would find something else to worry about.I have one that barely shows any idling hot,been working it hard for five or six years now.the others i have show between 10-20 hot and idling.
