had a 4bt do something kind of similar... It ended up chucking out the thrust bearing (#4 main) and the crank was walking back and forth about 1". Not sure how long it was like that, no problems were reported with the engine and it ran fine in the shop till i noticed the flywheel moving forward and back!
Dropped the pan and pulled out parts of the thrust bearing.... bolted the pan back on and sent it to cummins for the core on a new engine
heres one for ya... Never let a Deutz certified mechanic work on your Deutz engine...
He spent all kinds of time diagnosing this engine, replaced the injection pump ($4500). turbo ($3000) and tinkered with it for weeks...
The engine came back into the shop and i imediately noticed it was missing on at least one if not 2 cylinders and was actually spraying raw fuel out the turbo and from between the cylinder and head! uh oh...
Upon disassembly i found the root cause of all of the issues to begin with, the damn AFC line (steel tube) had rubbed through on the #4 injection line (surprisingly enough did little damage to the injection line) and thus the AFC was not seeing boost and wasnt dumping in the fuel. Im not sure exactly what had transpired after this issue had come up, or what that mechanic did, but i pulled out 3 of the 4 slugs and they looked like this!
I guess it all depends on where the pan came from and what color of paint they had alot of kicking around. All of the pans on our industrial engines (in various configurations) are all the light tan color on the inside and the engines have varied in color from tan/white/black/brown
well i got a leaky front seal. i gotta keep adding a tad of oil. i check every stop i make to clean the truck out or fuel up. im sure im not losing the lube in the oil. i keep it in the safe area. just a drip or two every stop
Nice carnage pics you guys have posted. I have seen some good failures at my job, no pics because work won't allow cameras in the shop. I have worked on a couple locomotives in the last few years that had major engine failures. One threw two rods out the side of the block. The piston, rod, and liner assemblies disinigrated inside the block. I have a piece of one piston from that failure cleaned up and on my shelf. It's about the size of a football. The result of this failure tore up the crank, damaged the block, and damaged the locomotive body, this was on a GM EMD engine. Had a GE dash 8 locomotive throw a rod, took out a cam segment, rear geartrain, a bunch of push rods, the articlating rod, and bent the rod across from it. Had a second GE let loose while being load tested for horse power. Engine was running full RPM and making 4400 hp and then it went BOOM. It then dropped to an idle, I opened a door on the side of the loco and found a rod hanging out of it and a cam segment on the floor. The engine was runing on 10 or 16 cylinders at this point. They make one hell of a boom when running full bore.
