Question about Ford F-250

1 Answer

I just did an low end job on my 1993 ford f250 7.3 liter deisel pickup which means i replaced the rods, mains, and oil pump in the engine. i lined the gear timing marks up on the crank, cam, and fuel pump gears. and now when it starts it cranks fine but it smokes like its getting way too much fuel and it idles really rough. it was running fine before i did the job with my dad but it was loosing oil pressure. now that i done this to the engine it has great oil pressure but runs rough until you get it up to a hight rate of rpms the higher the rpms the smoother it runs. so can you tell me what could be going wrong? i did notice one thing about the cam shaft gear though. the timing mark on the cam shaft gear that aligns with the fuel pump gear is not directly across from the cam shaft gear that aligns with the crank shaft gear.

Where is the oil pump on a 318,1992 dodge ram 1500


Inside the oil pan. Not an easy job. Just a note... Probably not the pump. Probably is the main and rod bearings on the crankshaft. Pull the engine. If really high miles rebuild the engine or replace it. If low miles (like 100,000), replace the crank and bearings. Unless a bearing has spun. You would know because there would be a constant knocking in the engine lower end.

Where is the oil pump situated on a CateraS 2001.Have low oil pressure when idling or at a red light.


Hi Rejean, I suggest you have the oil pressure sender unit inspected before thinking of replacing the oil pump. If it's the sender unit the job will be a fraction of the cost of an oil pump replacement, which means opening the engine. Regards John

Ive rebuilt the oil pump on my 98 bonneville and the oil pressure is still low and causes my motor to knock


The problem isn't with the oil pump. The oil pumps job is to move oil around the engine. What the problem is, the main and rod bearings are so worn out that it can't create oil pressure anymore. That's why you have a knock in the bottom end of the engine. The tighter the clearances are at the main/rod bearings, the better the oil pressure you'll have. The cam bearings also play a roll in producing oil pressure.

Low oil pressure at low rpms


Depending on tone and depth of "clicking" it could be anything from lifters to connecting rods or piston pins....

cheapest to expensive:

Replace oil filter

if that doesn't do it (which it doesn't sound like it),

Replace engine...

Because clicking/ticking/clunking noises while having a "low oil pressure" issue (most of the time) means the engine is destroying itself.

My 1996 ford ranger oil meter was low and a ticking noise in engine for a week. today the ticking went crazy and the truck shut down. how much to fix oil pump


This is not what you wanted to hear. I had a Ranger (Emerald Green) The low oil pressure was caused most likely by a rod end bearing that was for some reason worn therefore leaving a gap in the bearing mating survaces so oil was running out the sides of the rod end bearing causing the low oil presure. The ticking that went crazy was the rod end bearing that destroyed itself and fell into the oil pan.

Quite possibly you now have a broken connecting rod as for the reason it shut down unless the engine computer sensed ZERO oil pressure and shut off the ignition.

I can tell you your problem is probably not the oil pump.

I see the following instore for you
1. head removal / valve resurfacing
2. crankshaft polishing
3. rod end bearing replacement and possibly resizing

The oil pump is the least of your problems.

Just being honest so you can understand what could be instore for you. Sadly it is not cheap.

Help on changing oil pump 0n 1999 jeep wrangler


Pump is fairly simple...remove pan unbolt pump and reverse procedure. It is good to pre-lube pump and fill oil filter before starting engine. BUT: Keep in mind that a damaged pump is generally not the cause but the result of a failure elsewhere. Primary reason is rod or main bearing wear, resulting in debris scoring the pump gears and internal surfaces. Therefore, changing the pump will at best, slightly raise pressure only for a very short time. If after removing the pan, you find that the pump pickup is nearly blocked off by hard carbon deposits, you may have a chance of regaining pressure, providing bearings have not been damaged by low oil suppply caused by that restriction.

You didn't say how many miles were on the truck or if there was any clunking down around the oil pan. If your pressure gauge is wandering, your oil pressure sending unit may be bad. If the sending unit is OK, it is time to drop the oil pan.

You may have to drop the tie rod or sway bar to get it out. Check the oil pick-up screen for blockage. If it is clear, check the oil pump for excess play. Replace if needed. If the screen is blocked, clean it by soaking in solvent, replace the oil pump, drop the rod and main bearing caps and examine the crank bearing surfaces. If they are in good condition, you can buy .001" undersized bearings. Lubricate generously and reassemble. Torque to the correct setting, then put the pan back on. This job can be done by one or two moderately skilled back yard mechanics if supplied with a case of beer.

If the bearing surfaces are scarred, take the crankshaft out and take it to a machine shop. You are going to have to take out the timing chain on the front end and unbolt the torque converter or flywheel from the back end of the crank. This job requires a good bit more skill, so unless you have an expert mechanic on speed dial, take it to a shop.

Knocking in the bottom of ford 5.4 liter engine


If you hear it knocking no bearing replacement is going to fix that long term. Its best to pull it, the crank shaft will have to be turned or polished and or replaced, weather its a rod or a maine, and posibly line boared if its a maine thats knocking. Do it right and pull it.

7.3 liter will not start.


yes they are you stated that you have mech oil pressure did you install a gauge?. this is a fuel line pressure sensor on the right bank at the frt of the head this sensor is rail pressure that high pressure oil pump creates check you pressure there that will elimnate that head the other side is a little more of a pain to test. one other thing to keep in mind is that the cranking speed is very important, and have you checked the oil level on a 7.3 deisel if you are more than 3 qaurts low on oil you will trap air in the high pressure pump. this will cause a hard start our even a no start
