<VV> valve seats revisited (Engine Braking)

[FrankCB at aol.com]

That's why IMHO not just turbos and 140s but ALL Corvairs need at least  
ONE head temp gauge.

My  experience with dropping valves has mostly been when going from steady

cruising (no indication of overheat) to closed throttle exit ramp. I could

hill climbing to engine braking could easily be worse. I think most of  my 
cases 
of dropped valve seats were caused by a previous (months or  years) 
overheating 
from broken/thrown belts.
