oil pressure

Hi All i decided to accurately measure my oil pressure with a mechanical gauge and ultimately replacing the sending unit if necessary. Do you need to drain the oil to remove the sending unit? will it start pouring oil in my face if i remove it without draining the oil? Thanks in advace

Since its turned fairly cold ( like 5 to 25 below zero ) my oil pressure has been really low (like almost nothing) until the engine gets to about 125 to 150* once it get there it starts to read normal. Normal readings for me are (air temp is at least 5 or higher) in the upper 2/3rds of the gauge...

Hey guys ! So i have a 97 40th anniversary with 119k miles on it. About a few days ago I noticed the oil light come on for two seconds then went off. I pulled home, checked the oil. FULL ON OIL ! Very weird. My oil pressure on a cold start is on 3/4.. Once warmed up 1/4.. After awhile while...

Hi there, I'm hoping I can pick some of your brains. I have a locked 97 LX450 with 150k on it. I was messing around on a very very steep dirt hill trying to climb it (testing out there lockers ;) The engine was close to, but below, redline. I think the angle starved the oil pump, the pressure...

I just replaced the BEB's on my 1hdt with 160k klm. There were several with small pitting. #2 top was the worst. My oil gauge had been reading low since I got it but I figured it was just a faulty sender. Fired it up and found my oil pressure had improved. Before my reading at idle was almost...
