Home Forums Hunting & Shooting Hunter's Campfire oil light on at idle when engine warm

AI the combustion chambers and seat the pistons about .020" off the head.

Annealing the rods will also help.

Trust me. I'm an expert.

Good advice.

Sometimes the shims can also wear.

It could a bad o-ring. They don't cost must but the labor to replace one is more than the part.

BTW,

What color is the car?

And ...

Doe it have a grey or tan interior?

I had the problem many years ago. A mechanic told me to replace the sending unit and it fixed the problem.

I got more responses that I expected. This afternoon I'm going to put a manual oil pressure gauge on and see what it really is

Put 20w50 in it or straight 30 or 40. It is worn bearings and will likely still go another 100,000 regardless. If it is easily accessible you could shim the spring in the oil pump. I wouldn't sweat it past the thicker oil for three weeks.

That's the only and right way to find out if there is a problem.

10 psi at idle wouldn't bother me as long as the pressure rises as rpms increase. Some motors are good to go with as little as 20 psi @ 2000 to 2500 rpms. Instead of additives run 10w 40w and replace the filter. Oil filters can cause variance in oil pressure but usually on the high side.

Low oil pressure is not necessarily a sign of worn out bearings and that the motor is on its last leg. I'd look for other issues way before considering that diagnoses.

Ignore all the other BS I posted. I was just having fun with the variety of posts made that weren't on track.

We used to run 15 40 in everything. Cars, pickups, lawn mowers to Terex Scrapers.


Once I started running 5w30 as recommended in the gas burners I noticed the oil pressure actually went up.

I wonder if the heavier than spec'ed oil would cause the bypass to be open for longer.

30 PSI at 900rpm

might want to go to a lighter weight oil!

welp...now its down to 18psi after running for 20 minutes. 70psi at 2500 RPMS.

doesn't seem like I have too much to worry about at this point.

Sensor could be bad, oil pump could be weak, bearing could have so much clearance from wear that they just leak out a lot of oil and drop the pressure. Try the sensor first if that doesn't fix it look elsewhere or dump it.

Bad sensory unit
