Mine was doing the same thing. faulty sending unit forced caused low oil pressure reading and cut engine off. RockAuto has switches ranging from 8 to 15 bucks. The hardest part is gonna be the replacement. It is literally behind the block next to the distributor. A buddy of mine actually shattered it trying to remove it. Another thing you can do is, change the oil and get Lucas Oil treatment, its like 15 bucks. It helps to thicken the oil so that the engine gets better lubrication.Lemme know if that helps
so i am new to this whole forum thing .. i started this account so i could hopeful find out whats wrong with my truck i have a 96 dodge ram 318 5.2 l i have had the truck for a little now and the oil pressure was all messed up i think she heat sezzed ? i think thats how you spell it anyway i put a new oil pump and pick up tube in it when i start the truck it sounds great when i give it like 10 min if that it losse oil pressure and makes a noise when i hold it at 2000 rpm it has pressur and no noise at about 1500 rpm no oil light and has pressure but makes a noise i let of the gas and the oil light comes on and no pressure can some one help me thanks
If the old oil pump seized, did you also replace the intermediate shaft that drives it? Otherwise, the hex end might be stripped to the point that it slips in the oil pump, and you are not getting full pressure. Other alternative is, your bearings are smoked, and its time for a rebuild. You might be able to get away with just redoing the bottom end. (may not even have to pull the motor....) so long as the crank or rods aren't screwed up.
Sounds like you have a serious mechanical issue zx6rider, might be a sending unit but I doubt it's a bad pump or it would lose pressure on the increase of RPM at any engine temp. My guess is you have a clearance issue and as the engine warms, the oil warms and everything expands, you lose the flow through the engine causing the chatter or rapping noise you may be hearing.
thank you guys i did not know how to post my own thread so i post my ? under where i did ... the screen on the intake tube was clogged i put new pump and pick up i think the top end heat sezied how do i tell if its a bearing or the hex drive from the crank and if thats it how do i replace it .. the truck sounds great when i start it way is this ??
You need to find out what the problem is first..... I would get a mechanical gauge, and verify that you do indeed have a problem first. (which it really sounds like you do....) I just got a cheap 20 dollar gauge from the parts store.... its just temporary, so, doesn't need to be high dollar.
If you do indeed drop to zero pressure with a warm engine.... time to drop the pan, and have a look at some of your bearings, and the oil pump drive. (pump needs to come back off.....) If the drive shaft for the pump is worn, twisted, or otherwise buggered up, time for a new one.
You will also get to learn the mysteries of plastigage...... All it is is a claylike substance that looks a lot like string...... you cut a small piece off, stick it on the bearing surface to be check, and then torque the bearing cap into place.... the remove it, and compare it to the width chart on the package. (when you see it, it will make more sense.) If your clearances are out of spec, time for new bearings. Also, if the bearings are scarred, time to replace them as well.....
I would just pluck that sucker out of the truck and get it on a stand when you verify that you are losing pressure, if your pump seized, I am afraid you may have a decent amount of damage and you may be considering a rebuild or replace.
