Bula from Fiji
Did some searching of past threads- couldn't remember if I'd posted this problem before or if it'd been covered- I have an old Isuzu Pisces 40 (three banger) that originally had no oil
pressure gauge, only a burned out idiot light. We installed a sender and gauge, and it has always read high, like 60psi+, but lately reads off the numbers like 80+, 90 if the gauge read that high.
Obviously I'm concerned about blowing out seals
if this is correct.
So what could be causing it? Stuck pressure relief valve, clogged oil
lines? I have removed what I was pretty sure was the pressure relief valve (located near the filter, little spring-loaded pin-type deal) and it seems to move fine, not gummed up or anything.
Recently, from Tahiti
on, I've been running a multi viscosity diesel
grade oil (15-40) because I couldn't find a mono anywhere. Could that be the problem somehow?
has about 2000 hours, oil changed every 100 hrs, no smoke, purrs like a kitten, but I'm concerned.
Thanks in advance for any help,
