    i have an 88 f250 with the 5 liter motor. the oil pressure sometimes will drop off when the truck idles. while driving the pressure goes back to normal but sometimes smells a bit like burning oil.



    a friend of mine (an experienced mechanic) says to try checking the sending unit before replacing the whole pump. it causes a similar problem when it fails and is less expensive than a pump.

I presume you have checked the oil level... so it's likely you will have to have a new oil pump installed. how are you checking the pressure by the way. if it's by the gauge on the truck consider taking it to a shop to confirm you have no pressure

No oil pressure when hot


I am assuming you are going by the oil pressure gauge or warning light on the dash. If so, the first thing to do is have the oil pressure checked with a mechanical gauge to make sure the pressure really is low.
If you are hearing noise in the engine and the pressure really is low, could be a faulty oil pump, clogged pickup screen, or worn bearings.

Oil pressure is low . And its lifters tap at 3500 rpm


Oops. The lifters tapping tells me the engine is wearing out. The oil pump could be wearing. The passages for oil probably are gapped too wide. Need to overhaul or replace to fix.

1989 F150 351 oil pressure guage starting dropping to 0 suddenly and engine light comes one. When I rev the engine it goes back to normal but a soon as the rpms drop the needle goes all the way to the left...


Hi:
Usually your oil light doesnt come on unless you have less than 10 lbs of oil pressure. You either have a bad oil pressure sending unit, or your engines oil pump is bad. The only way to verify your engines oil pressure is to buy a direct reading pressure guage and install it on your truck, or have a mechanic check your engine oil pressure. Eitherway, you need to do something soon, because the long term effects of running with low oil pressure will ruin your truck engine.

Hard steering


Sometimes problems like this can be caused by incorrect tire pressure. Check also the tie rod ends if it is busted. Check for leaks on either side of the wheel if there are leaks on the steering linkages. If the car has been serviced the steering column may have been moved causing it to hit something under the dash.
