My Car Is Smokin! - PeachParts Mercedes-Benz Forum

I was driving the 300SE back from getting an alignment today and on the way home, smoke started to come out from under the dash and instrument cluster. I haven't done any work under there and I still have to check the fuses.

I'll pull the cluster and the underdash panel and look for obvious buened wires. I want to take it to my automotive class, put it on the lift and tighten up the exhaust and change out some fuel related stuff.

Weird.

Oh my !!

Did everything continue to work - such as lights, gauges, etc? What did the smoke smell like? Also- did you stop the car, or did you just keep driving and it stopped on its own?

Keep us posted!

OK, it's not smoking anymore. The trans seems to have purged itself of excess fluid. The dipstick marks are 3/10 of a liter and I put in about 1/2 a quart.

There is some A/T oil on the trans and lots of engine oil under the engine. I suspect the headgasket is bad and needs to be replaced. Time for valve stem seals when I get on with it. I'll also replace the A/T cooler hoses.

In my Auto class tonight, I had it up on the lift to check these things out. I wanted to change out my fuel hoses and filter. No dice, the pump/filter bracket is really rusted as well as the clamping bolts. Back for more parts. I also need the tank return hose and another short section of fuel hose.

Also, on the way to class, there was a sudden and loud buzzing under the shifter. I pulled over and listened for any problems. None found so I went on to class. On the lift, I saw that the shifter bushing was missing, so it must have been chewed up in the driveshaft.

Jeeze, this car is going to be new and I don't think I'll ever 'finish'.

So you think it was transmission fluid / oil burning that was coming in the car, rather than from behind your instrument panel cluster?
