[TR] Alloy valve cover oil consumption

[Brad Kahler]

Tony & All,

Working from a tip from Irv I went out and bought a PCV valve that I was
able to add into the line from the valve cover to the carburetor flame
arrestor.  My TR4 has the mid production emissions setup and my first test
drive with the PCV valve installed was good.  What I found interesting was
my idle RPM dropped from 800 to 600 once I installed the PCV valve.

I'd rather not install a catch tank as I would think if everything is
working right the oil should now stay in the valve cover instead of getting
sucked into the carburetors.  Weather permitting I'm going to take a drive
this afternoon and then see what things look like.

Thanks for all the tips and suggestions!

Brad
