I've seen it zap strapped thourally to the cam shaft gear. Then just remove the gear and take of the head. Not sure if this is the best way, but like I said, I've seen it done.

So, the gear can be left in place and will be kept under tension if I ziptie the chain to the gear?

It could have dislodged a large chunk of carbon from the intake and bent a rod instantly or knocked a hole in the piston.

Hmm, well, whatever it did, it was immediate. The smoke occurred instantly while on the freeway. Just the trails of oil that are running down the block from the mating area at cylinder 1 and 2 are pointing at a head/ or gasket failure. We'll see. Anyone with access to alldata or Mitchell, can you provide a step by step on the head gasket replacement process?

Or along the same line a large chunk of carbon or goo might have held the valve open so that when the piston came up it hit the open valve. Either way you have a toasted engine.
I used to have a 91 350SDL myself....lovely car but when I got it it had issues. We removed the head and did all the usual stuff for a valve job. The intake had so much carbon and goo in it that some of the intake runners you only had about an area the size of a pencil left for air to flow. Before removing the head I drove it for a while. When running down the highway it would sometimes pass something which I surmise to have been some goo or carbon and a huge puff of smoke would come out the back. I would only recommend buying a rodbender if you are prepared to convert it to a three liter block and can afford to make the conversion. Good luck!

Yeah, I did a conversion earlier this year with my 1990 350SDL, and used a very low mileage 3.0L. It's doing great. Just was curious if this was salvageable. I'll have to weigh out everything I guess. Here's pics of the 350SDL that now is a 3.0L, and some swap pics.
I have so many parts. I need to start selling off some stuff as I lost my job back in May, and am still working consulting jobs trying to get a full time position (paying for Cobra health insurance for the wife and I is killing me). I've got some real nice #22 heads, and bunch of other stuff. Maybe one day I'll get time to go through it all. Hell, I've got spread across 4 counties, lol. My place would be like VSTech's if it was all here!!

Well, I called the Service Dept. at the local Benz dealer to check the repair history of the car with the VIN. He said he couldn't print out or fax anything to me unless the work was done at that dealer only. He said anything done at other dealers was for the dealerships use only, but he said he would verbally check the history for me. The engine was replaced in 1995 by MBUSA, and the head was replaced in 2009. So, what do you guys think? If the engine has the upgraded rods, would they still bend in the hydrolock situation I'm seeing in cylinders 1 and 2? Also, how long should it take to replace a headgasket on this? I've done a 616, but the 603 has much more crap on it. Anyone done it recently? I'm still working as a sub-contractor doing data work and havent got a permanent job yet, so I dont have any vacation or sick time to burn to repair it. So, if anyone's done this recently, give me an idea what I am looking at time-wise. Then I can try to schedule it. Thanks guys. I still have the 3.0L 603, but with a replacement 3.5L, it may be OK to go with.
Thanks again!!

An engine from 1995 probably doesn't have the upgraded rods

It took me about 4 hours by myself to remove the cylinder head on a 3.5L - with the engine in the car. I would imagine at least double the time to put it back in. So my guess 12 hours plus. .

Is there a metal plate on the bellhousing with the rebuild part number / engine number?

Hmm, idk. I need to look. Is it visible from the top or do I have to get underneath it to find it?

From gsxr's picture collection on an ID tag for a rebuilt motor.
Others have reported they have not been able to find a tag on a replacement motor, which could signify a new short block. .

You have to remove the sprocket to remove the chain guide to remove the head. The cam can stay in place and you can let the chain fall into the abyss. The chain won't come off the IP or crank sprockets. I remove the cam because it means I can use a dime store triple square bit to remove the head bolts and I'm not handling a head with valves extended. It's only 12 bolts and a funky loosening/tightening sequence.
I don't know about the smoke but it's possible that chunks of disintegrated head gasket are lodged in the lifter oil journals causing valve train noise and poor running. In fact if you find a bad head gasket, remove the plug at the back of the head and blow the lifter journals clean. Guess what? That means the cam and lifters have to come off the head.
