Smoke after oil change, 1996 E300D - PeachParts Mercedes-Benz Forum

Hi all, this is my first post but I’ve lurked here on and off for a couple of years and always found what I needed in the archives.

Today I changed the oil for the first time on my 96’ E300D. Everything seemed in order until I started the engine, LOTS OF WHITE SMOKE! After shutting the engine off and checking the oil level (it was OK) I restarted the engine and after revving it a little the smoke cleared up. I drove a few miles until it warmed up and all seems OK now, but I have a check engine light.

I obviously got engine oil into the cylinders somehow. Any ideas what could have happened? I’m thinking it was overfilled until the oil filter filled. Will my check engine light reset after things clear out?

Thanks for a great resource,
MikeMc

When adding oil to the 606 engine, pour the oil so it runs towards the front of the valve cover down the timing chain case. If you let the oil run towards the valves it can smoke like this (and actually run away momentarily!) unless you let the oil run down for about 10 minutes or so.

I had it in the driveway, so I’m sure it all went toward the valves. In fact I think the funnel was behind the timing gears. Will this cause any permanent harm?

No permanent harm done.

Yeah, it's fine. In the future if you can't avoid having the oil run back (or you forget until it's time to start!) you can simply wait about 10 minutes after adding the oil before starting the engine.
