Trucks been down for about 6 months and finally decided to get it worked on. We initially thoughty it dropped a lifter bearing but it turns out the low pressure oil regulator on the front case was bad. Sound legit or not? Sputtered and shuttered when drove then just turned off one day. Bought new oil filter, cranked motor over forever. Not a drop on it. Mechanic changed the regulator truck runs fine. There are no other issues i should be looking for?

 

I wouldn't suspect anything else. The 6.0 stops running if the oil stops flowing...this tends to make it impossible to damage anything for lack of oil pressure.

 

Just making sure theres not some failure that causes that regulator to go bad like the low pressure pump and needle bearings.

 

You should be good to go, the needle bearings from lifter tend to take out the oil pump and it will never pump again till it is replaced. This is not the first regulator I have heard of sticking or failing. these pumps put out/regulated at 75psi if I remember right, but it is probably capable of pumping 100psi, that is a lot of wear on the spring, if these springs came from same vendor as the fuel pump springs maybe they will offer a BLUE oil pump spring LOL

 

I'm curious, did you have to take off the front cover to replace the regulator spring?
