<VV> Exhaust temp... (was push rod tubes)

[J R Read_HML]

Cash...  Normally the left bank exhaust runs hotter - well, it warms up 
sooner and cools down slower.  The evidence of this is the damper doors. 
Left opens first and closes last.  Why?  Longer exhaust log on left side AND 
the oil cooler is there as well.  So, it is quite possible that you are 
experiencing normal operation.

Rough running and right side WAY cooler?  Pull (and replace) plug wires one 
at a time.  If the Rs go down, that cylinder is firing.  If they don't go 
down, that cylinder (piston) is currently just along for the ride - and part 
of the reason that the exhaust is running cooler.

Later, JR
