    • Solved pressure issues - so far anyway
Installed on a 2004 F150 Lariat 4x4, 5.4, 3V (@180k miles): I did the full cam phaser - timing component job and replaced the oil pump at the same time. The M340HV pump fit perfectly and solved all oil pressure issues! My engine had obliterated its chain guides and ate 2 holes in the timing cover from the chain slap. It was a MESS inside. So if your Triton is tapping - Don't be a dummy like me and put it off. This problem will only get worse! I'm using Motorcraft 5W30 synthetic oil. At idle, I'm getting 70 PSI cold and 25 PSI hot. It also runs about 60 psi down the road. With the considerable damage my engine had, the oil pressure is amazing. My engine still has scored cam journals and probably the crank bearings too, so I didn't expect such great pressure! I would have replaced my engine completely, but I didn't have the money, so I'm hoping this fix will last me until I do. So far so good. I'm using the ratcheting chain tensioners as well as the upgraded rockers that have the smaller oil holes. The new rockers greatly helps the oil pressure up top. If you're already in that far to replace the pump - upgrade those rockers too! VERY happy with this pump! Oh an PS: Watch FordTechMakuloco on Youtube. He is the 5.4 MASTER and shows you exactly how to do these timing jobs and oil pump! ... show more

    • Great pump!
Review Image by Amazon Customer
Works great!!! Fits perfect, provides outstanding oil pressure. Used to replace OE pump in an F150 4.6 3v during a timing job. Essential upgrade to keep the timing and cam components happy in 3v engines. Make sure you pre lube the pump before install.

This fit exactly and is an upgrade from the factory oil pump. My oil pressure has increased. I recommend this item.
