I don't see how you guys think its a BHG, I drove over 200mi and my coolant level hasn't changed.
Smoking Issue: need help

Then it is extremely unlikely you are putting a large volume of coolant in the combustion chamber. Did you pour coolant in your exhast upstream from the cat? I didn't think so.
HC fuel unburned can also appear white. It is only black after partial burn.

So you think I could be running extremely rich. Never thought of that, might have to double check my timing too.
If you were just rich, your smoke would be blacker. Unburned fuel is like that, not just a rich mixture. Or a lot of water is getting in upstream of the cat. And then there is the oil part.
So to get white smoke, you're saying that I must not be getting spark somewhere? Or that by some act of god water is getting into the exhaust, and that there also is the possibility that it is oil. Correct me if I'm wrong.
Ok gentlemen, I have the results from the compression test. We went through all cyl. twice on a cold engine and here are the results.
First time through:
1. 175psi, 2. 178psi, 3. 175psi, 4. 175psi, 5. 180psi, 6. 180psi
Second:
1. 170psi, 2. 184psi, 3. 180psi, 4. 180psi, 5. 178psi, 6. 180psi

Let me repeat. If you don't have a noticable misfire, it is unlikely you have a large volume of coolant in the combustion chamber. You will have to find what is getting in the exhaust.
I'm almost certain it is oil, and some guys thought it could be bad rings hence the compression test. I understand I'm not getting coolant into the combustion chamber, the turbo is dead so I am currently in the process of ripping it out. whether or not that is the only problem we'll see.
I am having a similar issue like yours. When I first got my car after a few seconds of it idling it would start smoking white. I did the lexus afm upgrade and the 550s injectors and now it smokes on deceleration. I have the safc II and I watch the vf reading. I can rip into it in any gear and the safc shows 0v when I let off until it gets down around 1400 rpms and then it shows 4.7 volts and the smokes starts a boiling and I can hear a bubbling sound from the exhaust. It will not smoke a bit at 0v on deceleration. When the safc shows 4.7v on deceleration I can down shift 1 gear and the safc will show 0v and the smoke quits. I don't really know for sure if this has any connection to my problem but I checked my 02 sensor like JJ said with a propane torch and it failed the test. I thought maybe the 02 sensor was lying to the computer saying that it needed more fuel when really it don't. I have not replaced it yet.
^^^^ I don't smoke until the engine is hot or I boost. I have no idea what your problem could be, but for me smoke is constant once it starts.

My last 2 driftmotion 57 trim ct's have done the EXACT same. It's the seals for sure. I took mine apart and found the rear(hot side) seal rings to be f'ed up.
