HELP!!! Massive amounts of white smoke & milky fluid in tailpipe.

So I went outside today to start my e46 early since it's -10 outside here. Started fine and ran fine, went inside and when I came back out (5-10min later) the car had stalled out and there was massive amounts of white smoke.....

Pulled it I to the garage to look at a few things...opened the oil cap & there was yellow gunk on the cap, smelt slightly sweet (coolant?), went to the back of the car & looked in the tail pipe..... White thick milky fluid was seen in the tail pipe. (Picture below). Spark plugs had a small amount of fuel, looked used(replaced 4 months ago), nothing seemed to be wrong there. Tested the ccv with running the car without the oil
Cap, car started idling funny which is suppose to happen? That's as far as we got tonight...

Little more history.... Car has been burning oil since we did a motor swap in August, approx 1 litre between oil changes, engine codes will sometimes pop up, I always read them right away they have said misfire in cylinder 5. Turn the car off without clearing the code and the code goes away for weeks with no issues. Car doesn't seem to have a lot of power? Coolants never been low, regular oil changes with proper Castrol
Synthetic oil, air filter is clear, MAF is clean.

So I'm thinking the head gasket??? Can anyone else give me some insight on what this may be? Thank you.Click image for larger version

Re: HELP!!! Massive amounts of white smoke & milky fluid in tailpipe.

The yellow mayo is fairly common during winter months. Check your expansion tank for milkiness. If it is a head gasket you should have milky stuff in there and on your dipstick. Best of luck.

Wasn't the head gasket, it was the ccv valve, replaced it and the egr system, cars running great. Ps.... Car never over heated

Might want to re-think your choice of usernames too.

I was right yeah yeah its a genius idea other than this sucking oil from dipstick problem but other than that genius I mean I challenge you to diy a better ccv. I tried and blew another motor by just running a vent hose to the ground and my dummy but didn't remember

It sucks too so it sucked up enough water over a two three week period leaked into a cylinder and boom water doesn't compress hole in the block again h2o is your enemy with cars

H2O helps keep the car cool, so its not all bad

Then again, if you're running a ccv hose to ground level......
