Have you used an accurate oil pressure gauge to see what you have? If the pressure is so low it is not lubing rocker arms, the main bearings are probably shot. You could try replacing the pump and running thicker oil to get a few more miles from it, but may not work.

How can I cheat the Idle up? I'm getting a low oil pressure light at Idle, 800 RPM. I would like to increase the Idle to 1000 to keep from getting the light.


that wont work trying to adjust idle can be done on older cars with a carburetor or the older throttle bodies new vehicles trying to do it will set off check engine lights on most sensors sound more like oil worn out---oil filter or pump problem change oil and filter and do a flush ---and put in an additive such as lukas - royal purple etc---also why did head need replacing was oil pump tested

No oil to top of motor but 45lb at gauge rattels real loud


didnt specify yr-make -model-engine size engine but most engines like im saying most engines oil pump is at bottom of engine in the oil pan the oil pressure sensor may be sending out correct pressure but if sensor is down by filter/pump area thats where your going to get your reading ---the noise is your heads starving for oil problem can be sludge clogging oil from getting up to head ---oil filter collapse not correct oil for the vehicle or oil pump failing

I have a 93 Nissan Altima and it seems to be getting oil in every place other than in my heads is this due to oil pump or what could cause it


have you done any head work lately ( head gasket blocking oil galley to head)
thee are engines that supply oil to the heads via a hole in a main bearing hole
it has been known for the bearing shell to turn and obstruct that hole
to eliminate the oil pump have a mechanical gauge fitted to the block oil galley and get a reading if it is normal or within specifications then that will rule out the pump

No oil to the top of the head


It's common for that to happen on start up. If you're not getting oil to the top under acceleration then that's of concern. See if you have gunk built up in the head and oil cap. If you do then start with the cheapest fix which would be to have the oil system flushed out with a detergent. If no go there then you probably need to replace the oil pump.

I have a 90 plymouth laser I just replaced the head the head gasket and head bolts I am now getting a high oil pressure reading at dash guage and no oil is getting to the top end and lots of rocker no


Good oil pressure, but no oil on top of engine could be a blockage in the oil passages somewhere. You might try some very thin oil, run it a few minutes to see if you can get oil to top of engine. Other than that, I don't know, maybe somebody knows of a solvent or something that may be put in the crankcase, like Marvel mystery oil, or a Lucas product, something might work. Hope you find the problem, Jim.

Seems as no oil is getting to the top of engine


Remove the valve cover, start the engine and find out. If this is the case and the top of the head is not all gummed up with sludge replace the oil pump. It the top of the head is gummed up the inside of the engine must be desludged before you install the new oil pump.

Oil appearing in radiator, 4afe engine, is there awater gallery behind oil pump? checked head gasket looked fine


Still can be a cracked head gasket. Unless you are creating to much pressure in your engine. Just because you do not see any oil leaks does not mean that the head gasket could not be cracked
