1987 760 Turbo, I just recently had trouble keeping the car running. Two people told me that it sounded like it had water in the fuel. I put in Valvoline SynPower concentrated fuel injector cleaner, filled up with gas, and then also added Iso-Heet to remove any water. Since then the car starts up and runs fine, except now it produces lots and lots of whitish-grayish smoke. I hope it's not the head gasket! Maybe that was just a bad combination of chemicals? At first I thought that it might just be the fuel system and water being removed, but it keeps on smoking. The last couple of times I've started it, it didn't smoke initially, but would start smoking a couple of minutes later. After driving it today (with the smoking), when I got home there was oil splashed in the engine compartment, from the oil filler cap. I bent the tabs on the cap, and now it doesn't leak anymore, but it never did that before either. Any ideas?

I put my hand over the exhaust, had the condensation accumulate, but it didn't smell like antifreeze. It's not losing coolant anywhere either, the level has remained the same since the problem started. It's still smoking as good as ever, and is still running fine. We've put about 15 miles on it since then, city/low highway speed driving, and it's smoking a lot.

Today I noticed every once in awhile some fumes coming from somewhere around the turbocharger, or where it bolts to the side of the engine. Also, if you look just on the driver's side of the engine from the front of the car, there is a portion of the engine that has a small (about 2" in diameter) circular recess, which oil bubbles from. There is also an empty bolt-hole next to it. What is that, and why is oil escaping from it? Does it still sound like a head issue?

I'll check the engine oil level after that car sits for awhile.

Make sure the engine is not simply over-full on oil. We saw one of these, I think it was a 90 or so 740T, just had WAY too much oil in it, like 3 quarts too much!

At 2000 rpm POOOFFF the entire car would disappear in a white-gray haze. I mean it was ridiculous, it made a cloud you couldn't see through. The fire department came, the second time we drove it down the street- someone reported the smoke cloud!

It was kinda cool to find out a car could do that, but I'm glad it wasn't mine! Drained the oil to the right level, replaced plugs, and it was happy ever after...

Hope it's that simple! Good luck!

Well, normally the white smoke does indicate head gasket. How's your coolant level been? Sometimes you can put you hand over the exhaust(dont touch the pipe) and let the condensation accumulate, and if it smells like antifreeze, head gasket issues.

Sometimes the water remover makes your gas burn with a whitish smoke
