On my way home from work my battery light comes on so I am conserned and don't know what's wrong. Then the power stearing gives out.. Wonderful. Soooo I pull over to see my belt completly off and mangled in my engine.

i decided to take pics after i put the belt back.... so i reenacted the situation lol

the pics suck with the camera phone.

There must be a rash of these oil filter caps leakin at the moment lol Mine did the same but I found it before my belt came off

 

Was this after an oil change or just random? I make sure to replace all the o rings that come with the filter, and replace the one on the dipstick too.

 

Mine did the same think a couple months back. Almost like the filter backed itself out, as I had not had an oil change in a while.

My belt did not come off so It was not as bad as yours, but as an FYI some Simple Green will cut right through the oil when you start the clean up!!!

 

Don't know why, but I have never had the leaking filter cap issue. I do my own oil changes and I change all the filter seals each time I change the filter. Nuf said?

Had the same type of oil leak from the filter last week. Did not loose the belt thank goodness.

I used some simple green to degrease it and it is fine now. I plan to keep an eye on the filter going forward.

Interesting. Like others, I do my own oil changes (often) and always replace all the o-rings, and have never had a leak from the filter housing. I did have a problem with the crankcase vent covers leaking on the valve covers, and I had to remove and reseal them. I was rather surprised to learn that MB does not make or offer a gasket for these covers, so in my mind this is a straight up factory defect. In order to get a good seal I bead blasted the mating surfaces and used Permatex ultra black sealant. Seems to be working fine so far.

 

Are you positive oil caused your belt to slip off? My supercharger pulley broke free on its shaft and by moving fore and aft it caused my belt to pop off. You may want to check your pulley for the same problem.

 

Had the same thing on my limited. I knew I tightened the filter but it also looked like it backed itself out. I check every couple of weeks now to make sure it doesn't happen again.
