I thought that originally frank but it must be an awful lot of condensation to be as thick as this is...
I'll put a video of my coolant expansion tank bubbling as I think that is where I'm losing it from as I rev the engine... when cold the radiator is always low and the expansion tank fit to burst... something not right with it.
No loss in power at all tho.
Any ideas on fuel change? Used to get 320/330 miles to a tank... now 250 ish.
sounds like a blown HG fire-ring.
during load (includes blipping the throttle), the combustion forces its way past the HG, into the water jacket, pressurising the coolant system beyond normal, and just like a hydraulic piston immediately forces the remaining coolant past the rad cap and brims up the expansion tank. moments later the gas would bubble upto the rad cap and into the tank.
eventually the gas will fill the cooling system leaving most of the coolant overflowing into the tank and overheats etc etc.
during high vacuum idle, the intake vacuum sucks coolant past the HG to be burnt as a thick hazy white smoke during warm operation.
a quick test on a cold engine, open the rad cap, brim up if empty, start engine for afew secs to settle, then blip the throttle afew times.
normally the water level should just dip slightly with rpm and return back up with no bubbles.
if it bubbles after every blip of the throttle then the HG might be blown.
fit the rad cap and warm the engine round the block to heat up the exhaust pipes (the cold pipes in morning normally causes the exhaust to condense and emit white vapours).
with warm/hot pipes, if the expansion tank is overflowing & bubbling and the exhaust is still smoking white then the HG prob blown.
suggest replace with genuine victor reinz HG, make sure both the head & block surfaces are absolutely clean, dry, straight edge flat, (when installing the head, very easy for any residue oil in the oil return passages to trickle down and re-contaminate the cleaned head surface so also make sure those passages are oil free), and follow the torque procedure to the book.
checking ur o2, hook the laptop datascan up, warm up engine, hold 2k and the O2 should flick up down very quickly twice a sec.
