6.5 Turbo Oil Pan Damage

[1151]

Hello!

The latest surprise is at the front of the oil pan near the crankshaft. There is a large crack in the pan and it looks like there are two chains inside. Recently changed the oil, the dipstick continues to show full, and it does not actively drip oil when stationary or cranking. The truck does not run yet.

Clearly the oil pan will need replaced. Is this a sign of larger damage? What could have caused this?

All insight is greatly appreciated.

Thank you!

looks like a broken chain to me...

WELCOME TO THE FORUM!!!

The timing chain has gone amok, the crank pushed it through the bottom of the pan, you have some real serious engine damage as the cam is not turning so likely you have valve damage also at a BARE minimum.
It is not going to run.

Thank you both for the info.

Big yikes and very disappointing.

Is there anything worth analyzing before throwing in the towel and writing off the entire motor?

What would have caused this in the first place?

Thank you!

For some reason the cam chain broke, when it balled up at the bottom of the pan the crankshaft sprocket pushed it through the pan.
That motor needs to come out, the Detroit is definitely an "interference" engine meaning if the cam gets out of time pistons will hit valves so on top of whatever caused the cam chain to break you probably have a bunch of bent valves, push rods and possibly damaged pistons.
It would be probably allot less work and expense to find a good pull out engine.

Agreed it is an interference engine and timing issues generally cause damage.

Reading other 6.5 diesel forums, some claim to get away unscathed after a broken chain.

Maybe it is denial, bargaining, and outright coping - but I think my next step will be pulling the chain cover to assess what really happened. Assuming repair of the chain / gears / etc is even possible it may be worth attempting. Worst case I waste the time pulling it apart, and maybe small parts if it appears feasible. If the motor is already blown it can't get worse?

Has anyone ever seen damage like this? @Retiredwarhorses

you have to pull the radiator stack anyway to pull the motor, so get the stack removed and pull the front of the motor and perform as much of an
RCA as possible, you can run the motor with the stack removed if you loop the trans and eng oil hoses…

Unlikely engine will spin even if chain is replaced.
No way it will spin without chain or Leroy gears.
