General M275 V12 engine finds

Just wanted to share this found and what you think

1
here, a V12 engine rebuild specialist removed the V12 with the subframe and swaybar
this is on a S600
so do we need to remove our engine from below too ? hot !

second find,
this pro V12 rebuilder found a vacuum loss problem, very important for turbos too
the place if these seals is somewhere we never look or think of
checking mine tomorrow, I added part numbers

I also found why my engine sometimes smokes, and use more oil too of course

I have been looking for best tools for on-engine
gonna try this and some others
I will post a full threat of course

In the top picture, I guess that's a Maybach engine, as it doesn't have the W220/215 cast alloy sub-frame.

But in any case, yes, I think if you want to remove the engine, it would be easier to drop it down, with the transmission, on the sub-frame.

I know it's been a TON of years but is there anyway I can the name of the V12 builder you spoke of? I'm in Philadelphia and I can't find anyone to work on it. It has bad valve stem seal gaskets and its drinking oil.
Thanks in advance!
