SOURCE: changed oil pressure switch,still no oil pressure

The fuel pump on that model runs through the oil pressure switch so that if the truck looses oil pressure,It kills power to the fuel pump to prevent engine damage.you need to find the cause of the low oil pressure reading(possibly a bad oil switch).That would be the cheapest place to start,or have it checked with a mechanical gauge.Good luck,

SOURCE: oil pressure drops to 0 at idle

OOO not good sounds like some of the head gasket got stuck somewhere, or the gauge or sender is bad or got knocked around when repairing the head gasket. I would check that first. If that checks out will need to drop the pan to see if something got stuck in the pickup tube,might as well change the pump while you are there. Or worst case some thing wrong with gasket job impeading oil flow back to bottom of the engine. Was the oil and filter changed ?if so pull out filter and see if an chunks are stuck in it now. And change oil and filter again. Sorry that was out of order I had a long day

SOURCE: The oil pressure gauge on my 2004 chevy avalanche

it is probably the gage cluster. chevy has had a problem with this and it was recalled. so you might go to your dealer and ask him if they will replace the cluster. mine did that to but as time went on all the other gages went crazy or stopped working .i had to replace the cluster.

Jeep 360 rattle sound at idle in park


it could be a wrist pin, and im not sure if those amc's had hydraulic lifters but sometimes with old lifters when the oil pressure is lower at an idle the lifters arnt filling up all the way so they develope a little valve lash, and when the rpms are raised the oil pressure raises and fills the lifters. you could try chasing the noise down with an automotive stethoscope.

2006 chevy 2500 express cargo van .What is a good oil pressure for this van. it has 150,000 miles runs great


60psi cold / 30-45psi warm is ideal. I've seen (with that mileage) 45 cold/ 20 warm and that's acceptable - anything less start thinking about a new oil pump.

Alrighty. I've asked this a few times before, I have more info now. CHEVY 350 K1500. 1993. Replaced intake gaskets, (bad oil leak) dropped a small amount of coolant in with oil while doing so. Changed oil...


how did you clean the gasket off of the head? if you used a sanding disc the grit will eat up the bearings. are you reading pressure with a mechanical gauge? you have replaced all bearings??

6 psi @ 1000 RPM
18 psi @ 2000 RPM
24 psi @ 4000 RPM
this is chevrolet specs on oil pressure in your truck so you are within the range.

describe your idle problem more and i will try and help you with that

Oil pump is going bad in my 1999 chevy lumina


First we would need to know when this occurs. Asuming the oil level is at the full mark!. If the pressure goes up during acceleration and down at idle when engine is fully warmed up, then this is normal. An engine requires 10 psi of oil pressure per 1,000 rpm ( ex. 20 psi at 2,000 rpm, 25 psi at 2,500 rpm, and so on ) . If the gauge is moving back and forth erratically at idle , i would say the gauge is bad. If it drops to 0 while accelerating I would say your oil pump is bad. If from time to time it seems to work and other times it seems not to work, I would say the oil pressure sending unit for the gauge is bad. If the pump failed you would start to here a Knocking noise from the engine in a short period of time. Use the above scenario's to narrow down what it may be.

Tapping noise at 3000 rpm on 4.0 litre 1996 ford explorer.Valves are quiet at idle and up to 3000 rpm


have the oil pressure checked. i believe the specification is 40-60 psi at 2000 rpm. sticking valves and lifters can cause valve train noise. weak vavle springs can also be the problem. try running an engine cleaner such as gunk motor flush at your next oil change. follow directions specifically. obtain a product designed to aid in cleaning deposits on valves.

My oil and water temp and pressure flucuate when it gose from idle to driving


oil pressure is going to increase with higher RPM's ,at an idle it should be around 20psi,at running speed the oil pump is pumping faster and it could clime to 60 psi.
water temp though you should check coolant level or think about a new thermostat

Oil pressure


30 PSI hot idle is ok, 40-50 PSI at freeway speeds hot is good. this is based on using the correct weight of oil which is 10W-30W

Low oil pressure indication in suburban


Dan,
If your oil pressure actually dropped below 10 psi at idle, your hydraulic lifters would start to collapse. This would cause them to "tick" or "click" at idle. If you are not getting this clicking, change the sending unit.
