I am using Reinzosin sealant. Some posts say its the same stuff MB uses, some don't. Can't get a consensus, but it should be fine. I believe the application is half the battle.

0-40 Mobil1 has been used, or at least by myself since 100k miles.

When buying the spark plugs, don't use any platinum, resistor or nothing like that. They burn rich, decrease fuel economy and cause crappy idle and misfires. Been there done that. Beru has some good plugs for these cars I love. Beru 14 F-8 DPURX02

synthetic really cleans the engines sweetly.

The best engine sealant I found is toyota FIPG or the AC delco engine sealant which GM uses now, I also found that the tube dispenser tool is a very nice item to apply the sealant in the crevice.

when I sealed my cars breather covers I used the caulking tube of AC delco sealant in a dispenser and it went very quickly and very evenly - The sealant sets in half hour. I also bought the toothpaste tube dispenser tool where you can stick the tube in it and squeeze the handles to get a very good control on applying the sealant. I found it on a GM TSB.

The AC delco and toyota sealant are extremely robust. Infact I know of some indy shops that use them on all german and british engines.

Yeh my Reinzosin sealant comes with the toothpaste metal tool and it made applying it a breeze. At first I didn't know what it was, but then it made sense. I don't know how I ever used sealant without it before!!

this is the tool I bought - its great

I usually buy this sealant - as its easy and cheaper to get and you can stick it in your caulking gun tool. specially useful when applying it on toyota engine timing chain cases

Although it does not look like it the M-B sealant will fit in a standard caulking gun. That's how I use it.

the loctite 5900 which is MB sealant comes in a full size caulking gun tube also, its about 90 dollars from fastenal or less from amazon etc.

I think you can do more than two engines with it. - I prefer the GM one, its easier to get and sets quickly once the parts are assembled compared to other products where you wait a day and this 1/3 caulk tube is about 20 dollars

Finished up today. Drivers side looked just as clean.

While I was in there, I got around to doing the idler pulley and the fuel filter. I then disconnected the battery and inserted the key to make sure no residual power was present. Connected everything back up and on 2nd attempt to start it fired up and ran perfect.

However...I think the engine mounts are toast. I visually inspected them and they didn't look collapsed at all by any stretch, but while driving I noticed at idle that the steering wheel is shaking. Do you think this indicates both need to be replaced?
