I am real happy with the rebuild that Perkins Diesel Service did on my VE pump.
Sick Cummins
Bought this engine many years ago (2014) for another project. Now it's going into the Wagoneer if someone can resolve the problem.
It's a 130hp P pump, stock, came out of a FrieghtLiner MT35. Replaced the injectors for a no load mid speed miss, that did not
resolve the problem. Timing is stock. I did put in the 3200 GSK.
It starts easy. After about 1/3 throttle it starts to miss and blow white smoke and flames out the exhaust.

edit:
Compression was right around 400 psi for all cylinders.
Replaced the IP overflow valve, just in case.

Same here. He rebuild the VE pump that's in the Scout. I hope the new owners really appreciate it.I am real happy with the rebuild that Perkins Diesel Service did on my VE pump.
It will be interesting to see what they find.
The pump is fixed. All I'll say is it was a "very" expensive fix. The fulcrum in the governor was "broken". Shop said he'd never seen any thing like it before.
That is an impressive failure - for those who don't know, Perkins Diesel Service is "Family owned & operated since 1948".The pump is fixed. All I'll say is it was a "very" expensive fix. The fulcrum in the governor was "broken". Shop said he'd never seen any thing like it before.
Actually, it kinda sucks to pay for a unique part failure...

Finely got injection pump installed and got it running...........
Back to square one. The engine is not "fixed", same problem is still there.
Any new ideas on the problem?
Rebuild pump, new injectors, that eliminates a fuel problem. It starts up great, didn't half to bleed the injectors it started up and ran.
My first thought, could it be a broken valve spring? Didn't find one but did find tiny little flecks of what appears to be aluminum or copper on the valve springs. Guess I'll pull the the oil filter and see whats inside.

That material sort of sounds like bearing residue. Mains, rods, cam bearing, take your pick. Is there a curse on that engine??
Tommorrow I'll change out the fuel, could be bad fuel/old fuel. The fuel filter has a install date of 2019 and I have 5 gal of fresh Diesel ready to go.
I emptied the oil filter into a clean container, nothing unusual flowed out or was left on the inside.
And then I'll bleed the injectors/lines like Diesel was $2.00 a gallon and try again.

Might as well change out the fuel filter while I'm at it.
Those particles are large enough to see. An oil filter should pick those up. If you find more of that in the oil pan I'd think checking the bearings would be in order. Only so many places that could come from.
I don't understand why those particles are way up on top. My guess is that the oil filter bypass was open, could be from the previous owner/company cutting cost on a "dying" engine.Those particles are large enough to see. An oil filter should pick those up.

Going to cut open the oil filter and see what it's trapped.
For the engine exhaust flame I'm leaning towards the delivery valves being the culprit.
I cut open the oil filter and found only a very small amount of viable "aluminum" particles, about 1 speck every 4 pleats. In the drain pan I had under the oil filter when I too the oil filter off, the bottom fo the pan glistened like I'd struck gold. Except it's copper.
How much is too much?
Either way I think an inspection of all of the main and rod bearings is in order.
It gives me the excuse to fix some other problems i've been postponing.
The trans oil pan is seeping.
The T case bottom access panel is leaking but only when it gets warm.

Replaced the old fuel I was using and put in a new fuel filter. Pumped about a quart of new fuel through the IP with the transfer pump just in case it was going "bad" after 3 years.
Same result, no improvement.
Next task is to check the rod and mains bearings for wear and I'll pull the front cover and check that the timing gear are installed correctly.

Valve springs seems like a possibility. Never heard of valve float at such a low rpm, but I guess if a Spring is bad.
I thought of a broken/weaken spring. I was going to do the old tap the valve stem with a mallet and see if one has a different sound.Valve springs seems like a possibility. Never heard of valve float at such a low rpm, but I guess if a Spring is bad.
Next thought is possible burnt/cracked valve seat. This engine having the 7mm injectors I think that minimizes the chance of a crack between the injector hole and a valve seat.
Or maybe I set one of the valve clearance too tight, that would never happen....... will check anyway.
A valve seal or crack would run bad all the time, no? But a weak/broken spring might only be a problem at higher rpms.I thought of a broken/weaken spring. I was going to do the old tap the valve stem with a mallet and see if one has a different sound.

Your probably right.A valve seal or crack would run bad all the time, no? But a weak/broken spring might only be a problem at higher rpms.
If you got copper in the oil pan that's a pretty sure sign of bad bearings. Copper is the layer under the bearing surface. That would indicate severely worn bearings. If you pull the rods, Cummins recommends replacing the bolts. Not a high dollar item or you can splurge a little an buy ARP upgrades. Flame out the exhaust is a pretty good sign of bad pump timing or weak injectors firing at the wrong time. Seems another member had that issue recently. Fuel is burning coming out the exhaust instead of in the combustion chamber. Would also explain the white smoke. Fuel is hitting the combustion chamber when it's too cold to burn it. Seems like a tear down and rebuild is in your future.
