Was looking up the pump I got, says it’s not made for dod/afm cars because they require higher pressure. of course I don’t have dod anymore but was the stock pump a higher pressure one than what I got 10296.

Melling Oil Pump

Which Melling pump is everyone running on the 6.0l without DOD? Is the 10295 (std vol, High Pressure) sufficient or is there a need to use the 10296 (High vol and High pressure.) The 10296 seems like overkill on a non dod car.

Did retain the relief valve in the oil pan?

 

[blkchevyz]

I didn’t remove anything from the pan, so I guess so. That a bad thing? I thought as long as I had the non dod valley tray I didn’t have to block anything off.

 

[GT Drew]

The pan relief valve is supposed to limit the pressure the LVOM see to 65 psi. It was back up for the spring in the pump. The 295 pump is for stock engines/trucks. The 296 pump is the high performance engine pump. The M365 or 10355 is the highest volume for DOD. The LSA also used the DOD oil pump to give the volume needed for the piston squirters.

 

[blkchevyz]

So do I need to pull the pan and block off the relief valve? seems like 65 psi is plenty and anymore would just rob hp.

 

[PONY MAN]

Would first check the oil pressure with a manual gauge prior to replacing the oil pressure sensor and go from there.

 

[blkchevyz]

i'm just going to replace it since i have to pull it out anyway, i hate using cheap china crap lol

unless their is an easier place to access oil pressure than where the sensor is.

 

[GT Drew]

It your choice, I wouldn’t pull the pan just to do that. Your bypass in the pump starts to open first at around 52 to 55 psi. The one in the pan is a back up to make sure the LVOM doesn’t get hit with a spike of cold oil and blow seals. Unless you have an oil consumption problem that the PCV system sucks in too much oil. No read need to remove it.

Generally speaking, AcDelco GM genuine/original equipment parts line is better than the professional line. Typically, steer clear of much of the rubbish sold by many of the third party sellers on Amazon.

 

[blkchevyz]

new sensor did the same. so i'm wondering if my old sensor was a dummy type... where it doesnt move much unless its a drastic change...
i'm still seeing plenty of oily pressure so i guess i wont worry about it.

 

[PONY MAN]

Did the same as in identical oil pressure readings? Were you able to verify the readings with a manual gauge?

 

[blkchevyz]

yeah same oil pressure readings both via the scanner and the gauge. i wasnt able to find a manual gauge locally so i didnt test it that way.

 

[GT Drew]

Yes they will always be the same. The scanner and the gauge are both getting the signal from the same sender. Either borrow a manual gauge or buy a quality sender unit. The fact they were the same means the gauge is working well. Just save the time and buy a new sender

... buy a quality sender unit. The fact they were the same means the gauge is working well. Just save the time and buy a new sender

Sending unit/ sensor was replaced and presumably it is a quality unit.

 

[blkchevyz]

yeah it was an ac delco one this time.

 

[Jeff92se]

How bad was it to replace?? It's way back on the engine right?

 

[blkchevyz]

just get one of the sockets for it, its very easy. the hardest part was getting the connector off of it.

 

[GOPHERIT]

I can tell you for a fact----- After finding out how dificult it was to replace that oil pressure sensor an filter on my son's GMC 5.3 engine, that replacing that sensor (an the filter below it if also done), is super easy on the G8 V8 engine.

 

[GT Drew]

Buy or borrow a 1 1/16” deep socket. A big screw or a pick to get the filter out. If you can change a spark plug, you can do this.
