white puff on boost=
#2
Doubt it.
general head gaskets check:
Warm up the car on the road
Thrash it for 2 miles using high boost
Stop and open bonnet, engine running
Look hard at the coolant filler tube just in front of the battery
If you can see bubbles = gaskets gone
Turn off engine: still have bubbles a few seconds after turn-off? = gaskets gone.
The white smoke can be seen sometimes after the engine has been dawdling in traffic and you open it out a bit, residue discharging.
Mine did it the other day, and I raced it for the weekend 3 hours after the 'smoke'.
all is well.
Don't worry, be happy, unless you see bubbles...

You sure?
They usually fail in a way that gases escape past the damaged area to the water and not the other way round, but if the damage is bad or right nest to a water way...
It is an engine out job.
Have a chat with David at www.apiengines.com about options. He did mine when I had no time.

You can get sludge on the header cap if the coolant changes have been previously neglected/overdue, not drained flushed properly, or no/too little anitfreeze. I've even seen it on the expansion cap.
Looking at caps, dipstick and exhaust smoke won't tell you anything relaible, get a pressure test on the cooling system. And compression test done on the pistons. Then you will know for sure
Whistish smoke can be oil or excess fuel burning off in the exhaust. (its only blue or black when it is burnt in the combustion chamber).
