- Viano ex long, 651 2014. S211 646 2009 (till the Gov't drones blow 'em off the road)
2 issues,
one is sweet smelling white smoke when engine cold, goes away above perhaps 30 degrees.
Another is a puff of black smoke when stationary and engine revved.
I've stripped a fair bit out of the Viano. In truth I'm learning this congested, complicated engine as I go.
Removing intercooler there was a fair amount of coolant within.
EGR cooler not at fault as dry on the exhaust faces.
I see from youtube the fuel filter housing isn't likely to be the culprit, as the common leak there results in a wet inlet manifold below, that looks dry.
Thoughts appreciated.
