How bad does this sound?
 
I decided to go for a drive last night and show the 190Db to some friends in a nearby town. Checked the oil, a tad over the full mark as it was when I brought the car home for the first time. Car runs fine all the way there, then back with a detour to the store for groceries. On the last few miles of the drive, I've since noticed a VERY slight chane in the tone of the engine (more of a very slight nailing sound now, that was very pronounced when starting from a stop), and the oil dropped down to roughly 1/2 way between the full and add marks. Total round trip was about 50 miles. I've been running the car very easy since I bought it as I don't want to mess anything up.

The dipstick on these things appears to also double for additional crankcase ventilation. There was a very large amount of oil film all over everything around the dipstick tube. I believe that this is where all of my "leaking" is coming from as I had numerous places under the car where oil had travelled and then dripped onto the driveway. It drips alot of oil. I cleaned the engine and bay, and the driveway off this morning to clean up the mess. Any thoughts on this?? Thanx in advance.

Well, no one else is taking a stab at this. I'll make a comment. It looks bad. I have no idea what is happening but oil being flung out of the dipstick tube does not sound like a typical event.
Is there any chance that the crankcase ventilation tube is plugged causing the pressure to ventilate out the dipstick tube? If it isn't plugged, was any oil coming out of it?

The crankcase vent hose never crossed my mind. I'll take it all apart and check it out when I get home from work.

Wow....Paradise, Texas.

I went to school in Poolville, Texas...graduating in 1981. We played you in basketball regularly. Do you know someone named Brian Jackson?

Sorry so off-topic...

Diesel Power,

Check if you get alot of oily mist when you take the oil filler cap off while the engine is running. A little bit is OK but if it's really coming out it's not. If you are getting a lot then it suggests you have a blowby problem. The next step, assuming the crankase vent is clear, is to do a compression and leakdown test to see if you have a bad cylinder and/or possibly broken rings. Good luck.

Sorry, I didn't grow up in this area. I moved to the DFW area about 5 years ago, moving then to Bridgeport, TX, and finally where I'm at now.

I cannot do this test on the 190D. I've already tried and since there is no oil baffle in the valve cover, it starts to make a huge oil mess.

I cleaned out the crankcase vent last night. I didn't find any indications of plugging in the line. I did run the car for a bit last night in the driveway when I was done. When I got up this morning, there was a new lake of oil on the driveway, and no "new" mess around the dipstick. My guess now is that turbulence under the car put the oil where it did.

I'm still trying to locate gaskets for this car.

I would suspect a leak. My 220D has tremendous blowby, and only eats a quart in a hundred miles or so!

You can check for blowby by lifting the dipstick a little at idle -- same a for the oil filler, but no oil spray. Mine blows out there, but the mist coats the block, etc, and it's obvious.

Check around the front seal -- oil will be throw to the passenger side, mostly, and down the front of the block

Most likely spots are valve cover gasket, front seal, and leaking or missing chain guide slide bolts or covers. Lower oil pan gasket is a possbility, as is a bad oil cooler line (if you have one, I don't know!). This last will be serious, as if it blows, you have no oil pressure!

I've since cleaned the engine completely, all of the new oil is definitely around the rear section of the engine. I didn't get an opportunity to mess with the car any last night (fell asleep on the couch), but plan on getting the car on jackstands so that I can get a better view underneath. I don't want to start taking things apart untill I secure new gaskets for reassembly.
