Engine/Transmission (1994 - 1998) '97 12V Oil Pump Capacity?

Oil Pressure

I don't know why just the 97 would have a problem. As far as I know the oil pump and Bi-Pass valve are the same on 89 to date. (6. 7's) If you look at the oil filter housing on the front side (front of engine) there is a Plug cap that takes a 19 or 21 mm wrench. You can take that cap off and shim the spring under it and make what ever oil pressure you want. That valve regulates the oil pressure and or flow of oil that goes to the engine and the over flow goes back into the pan from there. On my 97 it held 73 pounds running warm and 36 at idle. This is with a real gauge. When I put the Bi-Pass filter on my oil pressure was still the same. On the oil filter housing you will see a 1/8 inch pipe plug. (next to the turbo oil supply line) That is the best place to tape for the Bi-Pass filter.

Does the oil pressure valve where out?

Mine kind of looks wonky

I have had pressure regulating valves stick

Giving some odd issues

After taking them apart no visual signs were noted

hi are you using a , factory oil gauge ? they suck not accurate , b electric gauges possible bad connection or ground or a good direct reading oil pressure gauge ? n whats your oil pressure fully hot running at 2000 rpm n at idle ?

harrisonm3 I hope that's a Baldwin oil filter I see and not a Fram

This is Frams side of the story:



from the August 2002 Cummins Bulletin®



TECHNICAL INFORMATION

It has been brought to our attention that a few Daimler Chrysler service

technicians are recommending that the FRAM PH3976 filter not be used on

Daimler Chrysler vehicles with the Cummins 5. 9L Turbo Diesel engine and

that use of these filters can cause damage to the engine. Daimler Chrysler

has informed us that they released a Technical Service Bulletin to their

dealerships communicating a potential contamination issue and recommending

the use of Fleetguard manufactured filters.

FRAM has been selling PH3976 filter for this engine application since the

engine platform launch and it has maintained an extremely reliable service

record. Late in 2000, Cummins and Daimler Chrysler brought to our

attention a low incidence failure mode in their Cummins 5. 9L Turbo Diesel

engine of the piston cooling nozzle plugging, resulting in engine failure.

The plugging was caused by contaminates lodging in the nozzle. The

contaminants included metal chips, calcium carbonate, polyethylene, and

styrene butadiene that are not associated with filter manufacture, and a

neoprene compound, which is used as a sealant on the tapping plate of the

filter. There were also several other engine warranty issues determined

unrelated to the piston cooling nozzle plugging that were part of the

engine failure sample. A small amount of neoprene rubber was used in the

FRAM filter as a sealant.

Throughout our investigation with Cummins & Daimler Chrysler on various

engine failures, no conclusive evidence was found to assign cause to

filters or other contamination sources. However, driven to satisfy our

customers, the FRAM engineering team made modifications to the design

eliminating the neoprene and expedited development and manufacturing to

release a revised filter model number to PH3976A. With the design change

on the PH3976A completely removing the use of neoprene, there is

absolutely no validity in comments that the Fram filter should not be used

for this application or that it may cause engine failures associated with

plugged nozzles.

The Honeywell Consumer Products Group warranty policy also protects the

consumer if it is determined that a FRAM filter is responsible for damage

to an engine due to defects in design or workmanship. This information

should be openly conveyed to our customers if they have any concerns or

apprehension about using a FRAM filter for this application.

There is also a reference to that in the recent TDR article about filters. Doesn't matter either way, Fleetguard Stratopore is the only oil filter for me.
