Probably a crazy idea, but would it possibly work to put in TWO head gaskets - one on top of the other, and maybe torque the headbolts an extra 5 ft/lbs?
I can't think of much else unless you could get someone with a machine shop to machine you a steel shim ring the exact ID and OD of the liner and .0014" thick - though you might even want it to be .0015" thick for a little extra sealing pressure against the gasket & head. Both crazy ideas, I know, but that's about all I can think of...

i sure would like to see some pictures of that cylinder because there would have to be a break between the top of the sleeve where the bore is machined for the sleeve land(sorta looks like a hat rim ,look at sleeve design in the manual) .
there is no normal groove at the bottom of the bore in a 617 engine,for holding the sleeve,and if some one installed a straight sleeve the head gasket couldnt possible hold because the gasket seals to the top hat of the sleeve. larry perkins lou ky |

The shim idea has better possibilites but something that thin might esily burn.

Having the liner a bit low means the gasket isn't getting the normal surface for sealing. But.. if it's been that way for a bunch of miles, I'd put a new gasket on and hope for the best. Or you could put in a used engine, which will have some new set of unknown issues, and see if it was the better expense. Just.. keep the old engine for a little while in case you decide the replacement was worse than fixing yours. Oh.. and broken temp sensors don't cause vehicles to overheat. You need to figure out why that happened too before deciding to fix or replace.

More info and pictures
I got a Carfax report on it and it didn't have any service records at all, and nothing from the car's previous life in texas except for the loan it was originally bought with.
I went to the shop today and took a bunch of pictures of the depressed sleeve and gasket, they can be seen Here http://picasaweb.google.com/parkerjohntwo/HeadGasket I could probably find a place/way to make a shim. Also, I miswrote earlier at some point, it's 14 thousandths of an inch or .014". As for the sleeve moving when It overheated, I don't think that was the case. The gasket has some kind of metal that compresses plastically (unrecoverable) to seal the cylinders and it had attempted to fill the gap when it was installed, meaning the cylinder sleeve was low when it was installed. According to the mechanic the gasket looks pretty new. There is also some faint polishing marks on the block that may indicate it having been polished at some point. I included pictures of it's numbering in the album. It also appeared to me that the gasket blew on a different cylinder then the one with the depressed sleeve too but I don't really know what to look for as far as that goes. There are pictures of all this stuff in the above link. patbob - The temperature sensor didn't have anything to do with overheating, it was a stuck thermostat that did that. The broken temperature sensor just made so I didn't know it was overheating till coolant started wafting into the cab. Larry - I don't have a shop manual for the car (yet) when you say it's like a hat I'm picturing an upside-down top hat, is that what you are saying? |

Just curious. What did you choose to do? Did you replace the gasket, and is it still holding? I'm not certain about your particular engine, but most Mercedes diesels have wet liners, so coolant may get past. Most would say that slipped cylinder linings would mark the engine's end of service, so I'm curious how you fared....

All the benz diesels I have seen are dry liners, including the 616 and 617.

I agree that the sleeve was probably put in short & then surfaced off. Just heating & cooling over time would allow it to move down. No point in trying to lift it, as it will just move down again. A new sleeve or motor change are the best options.

I am asking this question because on a Citroen, you CAN replace the sleeve with the engine in the car in all cars from 1934-1999 except the 2 cylinder A-series (2CV, AMI and Dyane). The shape of the oil pan makes it possible but it's not easy, like changing the oil.

These are some wet benz diesels: OM346 OM401 OM402 OM403 OM404 OM407 OM409 OM421 OM422 OM423 OM424 OM441 OM442 OM443 OM444 OM427 OM429 OM447 I agree with all of you that the best solution is a new block or an new liner (pushing back the slipped liner will see the same problem again). But, I was hoping jparker164 would tell us what he did. I'm curious if he simply replaced the gasket, and how long the gasket is holding, if at all.
