White smoke at WOT, but only on low tank.

Ok, when I thought I had my culprit something comes and shuffles the cards.

I have puking prestone, so I thought the slight white smoke I had when flooring the truck was prestone getting burnt. But there is several cause to puking coolant.

Yesterday I filled the truck and really gave it WOT runs on highway and also some 0 to 100. NO white smoke at all. All nice blackish smoke.

So I only have white smoke when pushing it with a low tank (below 1/4). Could it indicate something on it's way out or is it normal for the fuel to slosh enough to have the pump suck air?

Just wondering. Because if the white smoke with low tank isn't from burnt prestone, my HGs might be good.

Also, another topic. I have a little prestone leaking between engine and transmission. Could it cause air to enter the engine? I heard there is a plug there behind the engine. Can someone post a picture so I know exactly what it is and where to find it ?

I have no drivebility issues apart from the white smoke if I floor it under 1/4 tank roughly.

Again, thought white smoke plus puking coolant was a sure sign of HG failure, but it looks like they are different issues now.

I dont like to change part until im 100% sure. Otherwise I could change the wrong parts and keep the problem I was trying to solve ;)
