White Smoke - 220Sb

Post by dynamike » Mon 12 Jun, 2017 12:18 pm

So I noticed white smoke coming out of the exhaust of my new 220Sb. Uploaded a video of it here

Searching the forum I found some comments about brake booster and vacuum hose leaking into intake manifold so will have a look at that tonight. Any other ideas?

Looks like it's water vapour, was that when cold? Just after starting?

When the booster lets go the u can't even see through the smoke cloud!! The neighbourhood would call the fire department.

Yes, from cold but didn't seem to improve as engine warmed up. Only had it going about 5 mins this morning though.

We have had cold wet weather lately. it looks like water vapour from condensation in the muffler. You must never start the engine then shut it off unless you get it warmed up properly (180 on the gauge) it not only causes plug fouling because the cold start mech is running the engine rich but you will wreck the inside of the mufflers with moisture. get it hot then see if it is still steaming. it can take 45 minutes sometimes to get everything nice and warm. Unlike modern cars which have electronically controlled fuel systems our cars rely on 20th century technology and have to be driven, not just steered around the place. : :laughing6:

+1 on the water vapour.

White smoke would linger around a lot longer.

Listening to the engine sound it runs better than a lot of them!

Sorry but the video won't load for me. (Internet is crappy at the moment).

Another possible cause, if the vehicle is an automatic, is that the modulator diaphragm on the transmission may have ruptured and ATF is being sucked into the intake manifold and burnt.

I had this happen on my w108 and it can be quite alarming to see (my garage filled with white smoke on start-up), however, replacing the modulator fixed it immediately.

Hopefully, it is water vapour as the others said but just wished to indicate an alternative.

Good Luck,

Bill

Thanks for all your replies. I'll give it a longer ride once the rain subsides and will see how it goes when completely warmed up.

Started it up this morning when it was a lot warmer and less humid and no smoke at all. So conclude it was condensation. Thanks for everyone's replies!
