Question Smoke Under the Hood-ideas?

I was stopped on the way to work yesterday and I got a white-ish/gray-ish smoke from under the hood (both sides). Stopped, popped the hood and saw smoke/steam coming up around the intake near the turbos. Smelled like Anti-freeze, but couldn't find any signs. Let it cool for a few hours and took it home. Didn't do it again, the car runs fine as always, left it in the garage, pulled it out this morning, nothing on the floor...........left it home in case, but.........any ideas?

Mine started doing the exact same thing this week. I am pretty sure it is oil in my case and the leak appears to be from the oil lines to the turbos. I tightend them up but didn't help.

Later this week I will be pulling the intake out to get a look again.

If it smelled like anti freeze it probably was anti freeze. Check your turbo coolant lines, they blow and leak all the time.

Same happened to mine and it turned out to be a weakened hose clamp for the lower radiator hose. It only starts to leak when water temp rises above 110C and then suddenly all hell breaks loose. No leak no nothing before pressure breaches that point.

They sure do! They can harden from the heat or even soften if you have oil control lines leaking on them. They usually go without warning. If you smell coolant or see steam around the hood and headlight seams, pull over. Immediately. It looks/sounds scarier than it really is, as long as you don't overheat. It's no fun standing in a stream of coolant with a mushroom cloud of steam in your face.

Toadman-

No doubt. I t was coming primarily out the right side of the hood, when I opened the hood, it seemed to be on the right side above the turbos, in that general area. I'll have to pull it apart. Drove it today, no problems, but I only work 5 miles from the house, plus it's cooler today.

Mine used to do that too, and so did my friends.

Oil tends to leak around the y-pipe/crossover pipe. Might wanna check that area for some leaking oil. I replaced my OEM one with the Efini one and it hasn't leaked any oil at all.

You should really be able to tell the difference between oil and coolant smell. Coolant is sweet oil is oil. If its sweet then change the coolant lines, might be kinda rough but still a cheap easy fix.

it is probly leaking onto your down pipe.

and it might be a crack in the line that expands when hot

so if it sits after running the down pipe will burn it before it hits the ground and when it cools down the crack will close up

you need to put it on jacks and let it run to find the problem
