Rebuild, or not to rebuild OM616??
 

I have a sweet little 240D that I'm fixing up for my son. The engine runs fine, just has what I feel to be excessive blowby. If you take the oil fill off when it's running, hang on. Plus oil gets thrown around through the opening. Problem is, I have rebuilt gasser 4 cyl. motors as well as big block V8's, but never a diesel. Would it basically be same procedures, remove head, get head rebuilt, remove pistons, replace rings, new crank bearings, rehone cylinders, yada yada... BTW the motor only has 142,000 on the clock. I hate to throw in the towel on the block.

Signed, PO'ed at PO's:mad:

You stated that the "engine runs fine".

I take this to mean that you never have a problem starting it, correct?

If so, then why spend $2500. to reduce your blowby? Is this vehicle one that will remain with you for the next 15 years? Will your son notice the blowby?

I fail to see the benefit of rebuilding this engine unless you decide that you'll restore the entire vehicle.

BC ive seen the car, the blowby is pretty bad, we did take the oil filler cap off at the gtg while it was running and we were hit with oil 4 feet from the cap..but it does run pretty good, although some p/o re wired the glow system and only wired 3/4 of the plugs..

The question remains.........does the driver have any problem with the vehicle due to the blowby.........or do you fellows as enthusiasts have the problem?

it would irk be to some point but its surfs car.. i dont know why but i want a 240D.. it reminds me of a school bus

well there's one...and it's stick too! I can only guess it's a 240D given that. Lack of description makes ad a bit suspect but if someone is interest let me know and I'll have a look

No problems starting or otherwise. Just still relatively new to these diesels. There is a considerable amount of blowby but nothing to warrant a total tear down at this moment. Maybe during his Christmas break when it's not 5000 degrees outside. I was just curious about the process of doing the job. Heck, I pretty much just gave away 2 good running 617's.

You know. It looks like that car is in Florida. Check the background, Palm trees and all. Does New Orleans have palms like that?? Love that color too. Also has manual A/C. OOOOhhhhhh verrrry interrresting.

You've got the process down. But, the condition of the pistons is unknown.........maybe they're OK........maybe it's another $500.

It's the time and the cost that, personally, I'd avoid unless the vehicle is a keeper. You can find a decent 616 or 617 for under $1K and swap it over one or two weekends if the blowby is really bothering you and the engine becomes difficult to start in "cold" weather.

The thing that really kills me on this car....Attachment 35661

Looks like Lakeview area. They have palm trees with silly stilts to hold them up. Not native, but imported and they don't stick will in the sandy soil, hence the stilts.

I also have banana trees in my backyard. And they grow like weeds.

and agreed...car looks real nice in the photos which is what makes me suspect. Very clean looking palomino interior too..$2K seems a bit low unless it has 300K on the odo or something.

I'm like Brian - I would be hard pressed to tear into it if it runs as good as you say. How does it start? If it starts easily with just 3 gp's working then it is probably a pretty healthy engine:).

Cranks maybe 2 rev's and fires. The whole 3 glowplugs has bothered me since I've had the car. The harness that goes on the relay only has 3 wires as well as 3 female conductors in the plug.:confused: :confused: Oh well. still works fine.

Can't you just add the 4th wire? Plug opens right up usually.
