My Ebay copy works fine. I put it on a shop laptop that's only used for diagnostic stuff just in case but no issues with viruses or bugs. Works quite well.

I missed your "Brabus K8 becomes E V12" statement, twice. Lol. I was not familiar with the E V12 but a quick search definitely revealed some interesting info. I've had many discussions of how nice it would be to have this engine in a lighter car. 3000 to 3200 pounds was the desired weight in our hypothetical discussions. A 211 swap gets it pretty close though.

John I agree with you about the heat, its put a stop to my projects as well.
As far as a swap into a lighter car, if your looking for performance there are way better choices than these engines. Maybe for a nice sound or a small hydro, or airplane??? You know that V12 sound.
So hopefully doing all this work gets you more than 40,000 more miles, you said the other one crapped at 70,000.

As for better engines for a swap, I know of no other engine that makes as much power, as smoothly and effortlessly as the M275. The only downfall is the ignition coil design and they're just not as much of a problem as people make them out to be. Seems like an excellent candidate for a swap to me. But that's just my .02.

A problem with an M275 at 70k is an anomaly.

I'm failing to see how even Elroy could manage to screw it up so long as he doesn't just shove a prybar in the middle of it and reef on it.
Just a little patience working one end + the middle.... The other end + the middle.... I've sure got to wrestle with worse!

Neither of those engines are remotely comparable in terms of smoothness. Neither provide the same power and torque when used as is from their donor vehicles. No doubt about a LS based engines ability. Just not an apples to apples comparison.

Speaking of coil packs.... I've heard many and varied horror stories of coil packs breaking while being removed.

My car that started life with the dirty dozen will get the MB six liter for now. Perhaps in the future it gets upgraded with cylinder head work, exhaust that isn't so ugly that feeds a bigger pair of turbos and doubled up charge cooling. Cuz 740lb/ft is obviously not enough!

My comment was based on the fellow that mentions transplanting the V12 to something else. No I believe in keeping cars factory stock. Maybe doing a modification on some messed up junker.
I'm just saying there are better engine swap choices. Open deck engines are not good performance engines.

Not with a snaky cam timing set up as well as cylinders that will distort and move at the top, just not good for high boost pressures, yeah it may pull HP and T but for how long? Till the head gaskets or chain guides fall apart.
And sorry to say it is just a cheap to build design, it is a typical trade off. That is why I consider newer mercedes engines very expensive throw away items.

Please let's not clutter up the thread with what engine is best for whatever. Point of this thread being to leave hopefully useful information about the 275; timing chain information in particular. Thanks

On a serious note, any updates?

Updates....
Seems the timing chain issue with a dozen bent exhaust is secondary to the first failure.
Having pulled the timing cover it is clear to see what happened. The front main bearing spun and spit a bearing shell forward into the chain drive.
Anyone heard of or seen such issues in a 275? Or did I win the Powerball and Mega-Millions on the same day?
If I can figure out how to post pics on the BB I have several.
Looks like the EV12 project will need a different donor.

Having had the timing cover off of it chain drive looks sufficiently burly. Nice double roller chain with decent guides. Not too excited at seeing a spring tensioning the oil pump chain but it won't get away and will keep it quiet... Something that always annoyed in the Frenchie V6 things I've fooled with for decades.

That is an interesting one. That bearing lost its oil film for some reason, what oil was used? I have seen mains go and not the rods in one case of an oil pump failure, it was a large cat engine, it burned into 3 center mains, running at low power high idle for 30 minutes or so with zero oil pressure. I wonder if there is an oring like M113's have? And sorry to clutter your thread too.

Hi Guys,
do you know this Videos-Series?
https://www.youtube.com/results?sear...engine+rebuild
I watched every part and it is very interesting. If you have some questions regarding Timing Chain, Tasos sure can help you if he has time.
I would still recommend to use WIS.

I am curious as to whether a piece of chain guide fell into a spot on the crank gear where it jammed on the main bearing and broke the shell. What are your thoughts? I know plastic shouldn't be strong enough but nothing else would make sense here. It may be difficult to see what was first the chicken or the egg.
I guess another possibility is that the oil supply to that bearing could have been clogged which limited oil supply to the bearing.
Any pics of the broken chain guide?
