Exclamation oil pressure question

So I just had the bullet proof diesel kit installed along with a new hpop. After o got it back from the shop I noticed that when I dont touch the accelerator I. E. Idle the stock oil pressure gauge drops down to the low mark on the guage. When I accelerate the oil pressure reads exactly what it should pretty much in the middle of the low and high markings. Initially the shop told me it was a sensor. They have since replaced the sensor, tried a different hop, and installed a manual gauge that when the truck is idling it only reads 5 psi. They can't seem to find out what's going on with the oil pressure. Does anyone have any thoughts. Please help we need our truck back.

oil pressure question

Your dash gauge is for low pressure oil only. I would check the filter housing drainback valve and the filter bypass. What oil filter are you using, did you change the oil/ filter after the job? Might sound simple but bad oil and/or low oil level will cause low pressure oil problems. Make sure your filter is motorcraft and the housing and its internals were re installed correctly. Make sure you installed the filter housing drain valve as well. Make sure the standpipe and filter bypass wasnt damaged... To check for a good lpo pump, remove ficm and fuel pump relay, remove the oil filter and with the filter cap off have someone crank the engine and see how fast the filter housing fills up. Hopefully someone else more qualified will chime in shortly. Good luck!

The 6.0 dash gauge only reads 7 psi, so I am not shure what they are going on about other than picking your pocket.


Lord I shall lead them to the water but I will not try to make them drink

oil pressure question

Wait are u even having problems with the truck? Is there bad hpo? Its not uncommon for your EOP sensor to go bad. It will leak oil like a ICP sensor and give false readings.

The bulletproof set-up does not use the OEM oil filter housing.
Im wondering if maybe your LPO pump cant make up for the additional hosing and cooler due to some kinda internal damage, i.e. scoring. Or maybe the relief is weak. IDK... Just thinkin out loud

Depends on which BPD kit he has. There new kit DOES retain the factory filter.

How about oil level? When you add the BPD kit, it adds somewhere between 3-5 qts extra capacity to the system.

And i thought 15 qts plus additive hurt the wallet... You Still have to change at 5k with the bpd kit?
