[V8] Smoking V8

This is true, however......

COLD Oil pumps up into head, and with high viscosity it's a race between
draining out the return holes or going through the valve seals which have
excess clearance because of cold or ambient temperature. This is where 5W15
Synthetic helps this motor.

HOT When the motor is at temperature, the oil returns much faster and the
valve stem seals are much tighter because everything is hot.

I think this information is important because I don't think the seals are
necessarily defective on the V8, since there is little or no smoke during
normal operations. I know some have replaced the seals due to the COLD
phenomena.
