Took my E30 ('80s BMW) to work today and it puffed a ton of steam out for the first minute and then a little on corner stops until the exhaust warmed. The E30 has over 340K kms on its unopened straight 6 - I think your 'teg might be ok.BTW, my DC2R with 41K kms on it does it as well - and I can guarantee it's not oil
You've eliminated oil (no oil loss)
You've eliminated water loss
You've eliminated an increase in oil (water pumped into the oil galleries)
You've eliminated gas contaminants in your radiator
Your problems stop when your motor is warm
Relax and stop "warming your car up" - get in it, run the motor for 30sec to 1min as already pointed out and drive it. Sitting it still at idle is not going to warm the exhaust up quickly, driving it will. The sooner your motor warms up, the better. Warm-ups are a thing of the past. Hell, I didn't even do that in my old EH Holden
Get it checked for peace of mind - auto mechanics can check for contaminants in your radiator using gas readings as an internal water leak blows water into the cylinders/sump and exhaust fumes/oil particles into your cooling system.
Until you get it checked, STOP READING THIS THREAD AS IT'S F***ING WITH YOUR HEAD!
