Ram Year. 2016. Engine. 5.7. My truck threw a CEL with P1524 - oil pressure out of range - camshaft advance/retard disabled. 30 minutes later heading home on the freeway, oil pressure light came on, pressure gauge was scary low. Shut it off, checked oil, little low. Started it back up and pressure was decent but never got over 27 psi, gradually ...
Oil pressure isn't created by the pump. It's created by the clearances in the bearings. Tighter tolerances will create higher pressures, looser tolerances will create lower pressures. By contrast, a high volume oil pump will move (flow) more oil than oem and a high pressure pump. A typical high volume pump will include a heavier and oem spring ...
Hello everyone, Just checking if anyone has installed a 6.2L Hellcat oil pump on their 5.7 Hemi in their 1500? I was watching a former Hemi tech that indicated this Hellcat pump has a higher psi then the stock 5.7 pump which in turn can help with moving the oil to the cam/lifters. Searched out this pump online up here in Ontario and she at $176 ...
Removed the oil pan today. The pickup and “filter” looks good, all bolts for the pump are in place. Tomorrow I will either start with checking the pressure relief valve or try to put a small cup of oil under the pickup so it can suck directly from that one and then crank the engine. Re the pressure relief valve.

Easier than stripping it apart and putting a standard OEM oil pump back in. My truck is 30 hot idle and 65-70psi at highway speeds using 5w20 and the large diameter Mopar filter. My engine is bone stock, never been opened up, with 90,000 miles. With the small diameter Mopar filter I get 25 hot idle, and 55ish at highway speeds.
Find an Allen head but or socket that will fit the oil pump hex drive. I think a 10mm or possibly a ⅜ will fit but get one that will at least turn it. It doesn't have to be perfect. Put the Allen socket or bit in your drill. Put the oil pump pick-up tube in the oil and slowly turn the pump drive until oil starts to flow out of the top.
2019. Engine. hemi 5.7. If it's too long to watch, basically some guys who've tried the hellcat pump from the 6.2 (which bolts right up to a 5.7 or a 6.4 without mods) have been getting codes thrown which says "low oil pressure". Turns out the code is just a generic oil pressure code which means the pressure is outside of the expected bounds ...
Engine. 2500 6.4L Hemi 4.10's 'Off-Road'. Avoid high volume pumps. High pressure is the way to go. I used to build my own race engines back in the early 90's and only used HV on the first couple until I was educated on it. You will only be able to pass as much oil as the clearances will allow (like was already mentioned).
If you have a high volumn oil pump,then the Johnsons are the way to go,if you have the stock oil pump,i'd avoid them,as the stock pump doesn't have enough volumn to offset the extra leak the Johnsons create.Been a few guys burn up bearings using the Johnson lifters with a stock 5.7/6.4 oil pump.
