There are many reasona why engine exhausts with white smoke
A. Bad atomization of injector
B. Water in cylinder or diesel
C. Some cylinder doesn't workwhen operating at low speedon cold day
D. Incorrect fuel injection advance angle
I got the problem with my yuchai engine before and I got this from supplier:
Check the working conditions; replace theexcessive blow -by if necessary. Checkdiesel, if there is water in it,replace it,Otherwise, check for damage of the cylinder head parts which may cause waterleak, replace the damaged ones. Close theshutter door when the ambient temperatureis low, and make the operating temperature rise quickly to avoid running long timeat low temperature. Check and adjust fuelinjection advance angle.

QUOTE=victorjackie;7328253]Update:
Just got the time to manage to do the passenger side VCG (They mention its the easier side)
While still being very annoying and hard to reach(especially the lower bolts by the back, its done.
While taking out the old gasket from the valve. it cracked into many little pieces right away, like sand or hard plastic.
It was clearly the leaking source. Also under the valve cover was leaking into the exhaust manifold, exactly the way you guys described it.
I'm going to work on the driver side tomorrow, they mentioned theirs an extra step. Removing the fuel line, everything else is about the same I'm guessing, still ridiculously hard to access those bolts and lots of maneuvering around it.
I'm pretty sure this should solve the smoking problem.
Any tips and advice for the driver side would be nice before tackling it tomorrow.
Thanks again doods[/QUOTE]
Congratulations on getting the psngr side done. Did this fix your smoke problems? How did the drivers side come out?
