Just a little more . . . . .

I'm gonna have to sell the truck, as is.

I'll put in a pre-offer of $1500. I'd go higher, but it has an oil leak.

[Remps]

I'll trade you for 3 1st gens. I think once you get it all fabricated and assembled, it'll come apart and back together no problem if necessary. Just imagine owning a 6.0 and having to pull the cab to change one $800 injector, and your truck will feel like thanksgiving.

Getting down to the short rows.

Made the primaries lube-oil drain line . . .





Fits nicely . . .





The secondary's drain is similar in construction . . .





Got most of the stuff done . . . . . . . .





. . . . . . . won't build oil pressure .

[DodgeFreak]

Nice work! Oil pump need primed??

The Devil is fu.cking with me.

The side of the engine has been stripped from the truck for perhaps two months while I got stuff fabricated around the new spinners. At one point or another, I sealed the openings to the head and oil plumbing with aluminum tape to keep crap out. I may have cleaned the side of the engine before I sealed it so there's a chance i got water in the oil supply port coming from the oil pump. Couple that with the fact I drained the oil from the pan perhaps three months ago and kept the drain plug out for the entire time. With that, all the oil in the pan and most likely the oil pick-up tube drained.

The two above facts combined, I figure, allowed the oil pump to be completely drained of oil. I figure some water got in the pump when I washed stuff and seized the rotating sleeve of the pump assembly.


So, fast forward to my installing all the stuff this past week. Upon completion, using the manual fuel shut-off lever, I kept the fuel OFF while I spun the engine with the starter so as to fully prime the entire lube-oil system. Initially, I kept the oil supply lines OFF the turbos so as to allow new oil to flush any debris from the lines before I connected them.

Oil would not flow.


After many spins of the engine, nothing in the way of flow. Eventually, I got a spurt of oil from the turbo feed lines.

Now the weird sthi: With the fuel OFF, I can spin the engine with the starter, and get full/strong oil flow from the turbo feed lines, and the gauge shows the pressure rise to the normal range. The second I allow fuel to flow and have the engine idle, the oil flow at the turbos stops and the pressure falls to ZERO. Eventually, even that oil flow stopped.

WHAT THE FUCK!

I've found images of our oil pumps and see that some have the rotor of the pump keyed to its shaft. Some, are not keyed. I figure the pump was seized and my spinning it, had the rotor shear from its shaft (most likely not keyed). It's just tight enough that spinning the engine at low RPM with the starter, has the pump spin like it ought to and build pressure. The moment the engine spins the pump to idle RPM, the volume the pump tries to move is too much and has the rotor go to slipping thus, the complete loss of oil flow/pressure.

I've still got to pull the pump and confirm this. I was so pissed with these events this past Thursday, that I walked away from the heap and just went to the coast Friday for the weekend to cool off. I ordered a replacement pump from Pure diesel Power Thursday evening for right at $100 (anywhere local to me wants $300).

So, I come home this evening from work only to find PDP thought it would be cool to stick a the new pump in a USPS bubble-envelope, and have USPS apparently slam the sthi out of the thing along the way. Such was forceful enough to literally break the two screws that holds the ring on the side of the pump.


BTW, I WILL put a "Hit" on the next person who suggests I install a mechanical pressure gauge and check again. I ask that they READ the words where I say I've got the turbo feed-lines off and am looking at oil flow, and not flow.

F! M! D!

Contact Garrett directly. He will take care of you

Having now pulled the engine lube-oil pump, I find it as it should be.

The only thing left is that Cummins oil filter relocation plate that covers the engine oil cooler. There's apparently a gasket that's not right. Recent research has shown they can be a pain in the asz. So it is.

[PToombs]

Wow Dave, that sucks! I had a 4bt shear off the key in the pump shaft once, the pickup had a small hole worn in the mesh one of the valve seal springs broke and migrated thru the pickup to the oil pump. Needless to say the 4bt had more horsepower than the key could take and it sheared when the spring got in the rotor.
I've never heard about that gasket being weird to get right.
Good luck, you'll get 'er!

[Farmboy]

Don't worry.. we all have those days..

[oldestof11]

I am sorry but that meme is too funny!

[BC847]

Got the mess put back together. As expected, the oil pressure is where it should be. Allowed it to come up to operating temp. Tightened a couple of minor oil leaks. Later found a couple more minor leaks that are gonna be a pain to get to (naturally). Drove it to the automatic car-wash. Transmission was acting a fool along the way. Remembered it dumped a gallon when I pulled the dip-stick tube a while back in the early fabrication. Had to stop and put in trans fluid. Took the long way home . . . .

That at the end of the video was my sign. . . . . . so I took it home and shut it off and went into the house. I'll tighten all the bolts tomorrow on the stone-cold engine and properly secure the boots on the IC feed-pipe.


Then get the sensor wiring, etc sorted out as well as complete the air filter plumbing. And all the other sthi.

[fatty]

That's a very scary noise to hear. I've had it a few times and almost crapped each time.

[PToombs]

Good to hear you got it sorted out Dave. I laughed my ass off at the video, BTDT a few times myself. I was laughing WITH you, remember that.

[dazedandconfused]

Glad to hear the oil pressure issue was easily sorted out and you have it running.
