Engine Oil Pump

This oil pump is an upgrade from the stock one. Engine has really good oil pressure.

Doing a full timing job on 08 Expedition 5.4 3v and fordtechmakuloco’s video recommends these pumps that have more volume and more pressure than stock ford pumps, and had a thick cast backing plate that does not flex and lose pressure at higher rpm. Make sure you have an 8 mm flex head ratchet wrench and a cat claw to remove and install the oil pick up bolts. My complaint was even after priming the pump it seems to air locked and out not build pressure. I had the crank position sensor unhooked so it would not fire but no pressure. I ended up removing the motorcraft fl820s filter that as a one way check valve and installing a cheapo filter that I verified let oil drain back down, and using using my mechanical oil pressure gauge hose installed upstream of the filter and a one gallon garden sprayer to feed oil through a 1/4” barb to 1/4 npt that the oil pressure gauge had fitting to match through temporary gauge hose into the top of the fully installed pump. I do not know why the pump needed all this to finally build pressure but Melli g could certainly do a better video than the one where they are pumping oil in the oil filter housing that does not make it to the pump

The majority of issues with the 5.4 engine stem from oil volume and pressure inefficiencies. The Melling M360HV oil pump effectively addresses both problems, offering a reliable solution. Revitalize your F-150 by installing this high-performance pump. To ensure authenticity, purchase genuine Melling products from the official Melling store on Amazon!

Fit perfectly well worth the money.

This is not like installing a door knob! It's an oil pump. The engine needs to be disassembled to some degree to get this installed.But it does the job. Increased oil pressure and oil flow. Something you need in an engine with lot's of wear and tear due to high mileage. When cold, pushes about 90 lbs of pressure and warmed up goes down to 40lbs or so.F150 5.4l 3V

This is a must if you are tearing down past the timing chains for any fix on a 5.4 liter 3v. The pump was of great quality, but make sure you get an 8mm flex head gear wrench for the one oil pickup tube bolt, or you will become very aggravated. Take your time on this to make sure it is right, it took me many time squirting oil in through the outside oil filter fort to prime the pump; literally 10 tries, you don’t want to worry if you put the o ring back on or if the pickup bolts are tight enough. Prime with crankshaft sensor unhooked and do it before putting the fan and shroud back on, I used a differential suction tool to squirt oil in and a regular Fram oil filter. I tried multiple ways that I seen online and had to recharge the battery once, but when it primed I was good to go!

Showed up in timely manner, but without O-ring. I have installed it but haven't run the motor yet. I'm sure it will be fine, if not I will update this review
