Overshot's Blog

[Rawze]

I absolutely hate to see anyone with that kind of troubles. This is an interesting thread though. You posted oil sample reports from all the way back since june of last year, and it had small hints of this sort of thing in it even back then, but everyone mostly missed it because it was so minor. Then in august, you posted this...

I'm at Mr. Hagg's so I'm sure we'll figure it out.
But I will still appreciate any and all feedback.
God bless cummins

-- Who could have known, but a gallon per month is definitely concerning. It sounds like it finally got bad enough for someone to find. -- Totally sucks.

Those 2250's are notorious for #5 liner to leak.

Make sure you raise the liner height to 0.014" when it is re-built and that it is hand torqued, and that it sits over night, then re-torqued, etc. like suggested elsewhere on the forum.

Mr. Hag has a brand new certified short-block in his shop right now that came straight from the warehouse that he is going to have to pull apart because the liners from factory are not correct. Some are 0.011" and some are 0.012" and a couple are 0.013". there are even differences from one side to the other on them. -- This came straight from factory. Must have been built on a friday night? -- Who knows, but it is considered "in spec" according to the book. I know I would not want it in my truck like it is though.

Do you think if that short-block had made it to a dealer, that they would have bothered to make it right before using it? -- Very Doubtful.

I say Cudos to Mr. Hag for checking, finding, and then taking action on this before it ended up in someones truck.
