  • This is not a simple problem. It is caused by either excessive wear or a restricted oil pickup. The power loss is from the valves failing to open fully from the collapsed lifters. The 2.9 oiling system supplies full oil pressure to all engine galleries at all times. These galleries include the rocker pedestal gallery which feeds both rocker shafts with full oil pressure. Check for a mayonnaise like deposit in the oil fill tube that indicates coolant in the oil, likely a cracked head. Engine damage will likely be severe in this condition and will make any cheap fixes less likely to work. For a fix not involving an engine overhaul first try Shell Rotella 15w40 to sustain oil pressure,it should help if the pickup is not restricted. Replacing the rocker shafts and rocker arms with new units might help as they recieve full oil pressure. I am currently running a 2.9 with 2.8 solid lifters adjusted to 2.8 clearnces.This will stop noticible lifter noise at highway speeds and should cure the power loss if you decide to do it. I measured a 2.9 block extensively and concluded a 2.8 lifter should function reasonably well, leaving about 10mm lifter bore thrust contact at cam base circle. 302 solid lifters can also be used and are more desireable but out of safe range for the rocker arm adjusters requiring aftermarket rocker arms or shorter push rods. Cylinder heads must be removed to replace any lifter. Of course, a high volume oil pump with a new pickup won't hurt, but try the least invasive solutions first as if the engine is very badly worn the pump won't help much either.

I had to replace main bearings in my 2.9 after 140k. It lost oil press and started knocking. This is caused by main bearings being worn out. The main bearings are what hold your oil pressure.crank bearings are the main bearings.every 100to140k they wear out and when at idle no oil pressure. Hope this helped. Ranger chuck.

The lifter noise might have been a bearing going bad or a piston ring. if you lost power you probably lost compression on one cylinder. Try checking your compression with a compression tester screwed into your spark plug socket. here is a site with a procedure.

Lifter knocking in my 89 ford ranger


A lifter problem can only be fixed by changing the lifter. You might as well change all of them because it is just as easy since you have already had to take the heads off to get at the noisy lifter. While you are at it, get the heads reconditioned or a valve job. More than likely the oil was not changed as often as it should have been. Dirty oil works like sand paper on the valve stems.

1996 Ford 300 six cylinder loses oil pressure when engine warms up


first you will have to say what the oil pressure is cold, idle and 2000 rpms and then hot idle and 2000 rpms before a decision to advise about a rebuild can be made
there are many reasons oil pressure can drop and not all require a rebuild

My 1989 Ford Ranger 2.3L 2wd has a problem in the oil pressure area. The pressure gauge at idle says normal but when accelerating it goes past Low. I replaced the pressure sending unit and it didnt...


I would take the sender out and install a temporary manual gauge (we use a manual SW gauge connected to a 3' length of 1/4" high pressure hose). If the oil pressure is normal on the manual gauge then about the only thing left is the gauge itself.

Location of fuel pump relay on 89 ford ranger 2.9 v6


It's powered by fuse #1 in the battery fuse box, so I would think it should be right there somewhere. If it isn't labeled, see if you can turn the box over to see where fuse #1 leads to.

i hope you changed all the fluids. New oil,coolent,trans. oil and draind all the old fuel. if not the fuel injecters need to be cleaned but first check to see if the crankshaft can be turned if you can you may save that engine.
