So, started the spring tune up this weekend on the 82 300td (It's amazing what new filters and some new fluids do for a car!) and found that the drivers side motor mount is shot. I guess that explains the growing 'Hood" vibration I have noticed over the last few weeks. The car has 112k on it. I think it blew with all the cold cranking I did since after xmass when my glow plugs wet out. I think the engine "touques" that direction and some mornings I had to really crank the beast to get her going! (I've just replaced the glow plugs and now the car starts on a dime!) So my question is: How hard a replace job is this? Is it a full motor pull? WOuld a neophite be better served getting this done at a shop to make sure the motor goes back in in the right way? Any thing else I should be looking at while I do this repair? Thanx in advance! __________________________________ Do you Yahoo!? Yahoo!

Ho there! Visual inspection. It's all "mushroomed out" where the rubber bushing/mount is splayed out around the mount and mounting screw and it generally looks like it's failing. Plus I've picked up a fair amount of vibration on that side of the car and it vibrates something ugly at idle. At power, going down the road, it's still real smooth. The one on the passangers side looks good. No cracking or mushrooming and it looks like a small 2'x2' rubber box, where as the drivers side looks like a partially flattened rubber pancake. - --- steve d wrote: > how did you test the mount? > STeve > > ----- Original Message ----- > From: "hue wong" > To: > Sent: Tuesday, February 24, 2004 6:01 PM > Subject: [db] Motor Mounts gone wild! > > > > So, started the spring tune up this weekend on the > 82 > > 300td (It's amazing what new filters and some new > > fluids do for a car!) and found that the drivers > side > > motor mount is shot.

Hue, Its not a horrible job.... It can be accomplished with a jack and a block of wood and a whole lot of patience....... My engine mount is "going" as well as I have had the same glow plug problems with my 300SD on really really cold days (yes sometimes it gets into the 20's here in Hotlanta)..... Although right now I am absorbing information on brake calipers as of the 30 or so brakejobs that I have done in my life I have never run into complications as I just have with my car. I think someone else on the list has replaced their engine mounts before having a "catostrophic" engine failure :( Robert Chase hue wong wrote: >So, started the spring tune up this weekend on the 82 >300td (It's amazing what new filters and some new >fluids do for a car!) and found that the drivers side >motor mount is shot.

Assuming the mounts do need replaced, it does not involve removing the engine. You do need a jack to lift the engine a few inches, and it helps to have a partner there with a pry bar to help line things up on the reinstall. Other than that, it's quite simple: remove the two bolts on the old mount, jack up the engine, remove the old mount, place new mount in same position as old mount, and then the fun stuff starts. Lining up the holes for the bolts to go back in while you try to get the nuts started from underneath. Once you got the nuts started, let down the jack and tighten to spec. While you're under there, I'd replace the engine shock and bushings - you're going to under there anyway, and the difference it makes to the smoothness of the engine is unbelievable.

Known problems with the 3.5L OM603 powered machines is the engine. :) Provided I remember this right, it's something about the factory connecting rods can't deal with the extra torque that the 3.5L makes over the 3.0L, which IIRC comes from boost as well as displacement. The connecting rods fail, and the cylinders get ovaled. If you're lucky, you only have to replace the shortblock (or the connecting rods, pistons, and sleeves), but often times it overheats and nukes the head as part of the self-destruct process. If the owner that is selling it has a receipt for a new engine fairly recently AND that engine got the updated connecting rods, you'll love the car. If not, budget about $8000 for a new engine. The big sign that the end is about to begin is oil consumption goes way up with no apparent loss of power - somewhere around a quart per thousand miles or more on a seemingly happy, lower mile engine.

So when I climbed out of the Benz this evening, I noticed I had left a dotted trail on the driveway. It stopped dripping after a minute or so. When I opened the top of the coolant reservoir, copious amounts descended from the same spot it had dripped from previously (and the reservoir appears to be empty). The dripping liquid was a pale color, fairly odorless, and only a little sticky, so this is probably the orange MB coolant, no? How could this have happened?
