Ford 5.4 Why you want a Mellings High volume oil pump!!

[@FELIXTHECATRAPS]

Thank You! This Means alot to me.

Do you recommend the 60psi or the 80psi oil pump from melling? Im about to do a timing overhaul and i figured might as well change the oil pump.

I have been going with the higher pressure pumps on fords lately as I have had one high volume stock pressure pump not provide enough to eliminate the cam phazer rattle on one truck, going to higher pressure did the trick. I think that truck had excessive wear and needed it though, most trucks I have done seemed to be just fine with stock pressure high volume.

​@@A2J_TimThanks man

Thanks for this. I have a 2007 F150 that's in good shape and has in general been well maintained. It has 500,000 Km on it. I have the cam phaser tick noise. But things seem good otherwise. I can't detect any rattle on start up or any other noises from anywhere near the heads or from the timing chain but I'm not that experienced at detecting these things. I'm going to visit a mechanic friend with a computer and have him try looking for this effect and listening. Are there other symptoms I can look for on my own that might indicate the need for a timing set and oil pump job? Would you recommend doing this (expensive) job on an engine with this many miles?

if the rattle goes away shortly after start up, chances are your timing chain tensioner seals are leaking and your timing chain is stretched, if it rattles at idle your phazers are not getting enough oil pressure, you can try unpluging your phazers and see if the rattle goes away, if it does your phazers are forsure not getting enough oil pressure. if it doesnt then its probably timing chain slap from a stretched chain. I recommend looking at live data on the scan tool to see what the graph looks like, if its choppy your phazers are not getting enough oil pressure and or are failing.

​@@A2J_Tim got it into my friend's home shop this weekend (he's a certified mechanic and does some side work) - we put it on a computer and listened with a stethoscope. Turns out noise is not coming from phasers, but from back passenger side cam. We put it on his computer and timing is really good, graphs are solid and not out of variance. He recommends a new camshaft, maybe lifters/followers but that phasers and timing chain etc. are likely OK. Oil pressure is good. He doesn't have the Ford timing tool and cam tool. I'm thinking I'll just find those for him. Will start looking for new (OEM or good quality) cam parts. While we've got it open should I just get a new updated OEM phaser installed too?

@@GuyKelseySaskatoon could be a collapsed lifter, some times ticking sounds can sound like they are comeing from one area but the sound can resonate through the engine and sound like its coming from another part of the engine. I still highly recommend the high pressure high volume oil pump though. But do as you feel is right for you, your friend is very likely correct. also the oil pressure gauge in these trucks is not a gauge, its a switch that activates the gauge to put the needle in the middle, its litterally an on off switch, its not actually showing you oil pressure, the only way to check that on these trucks is to connect a manual oil pressure gauge to check what the pressure actually is.
