I have seen many 4,6,& 8 cylinder chevy engines with stock "o" ring style valve seals that do not use any oil.
I have seen many umbrella seals that have cracked over time and use oil and p/c seals that have led to oil starved valve seizing.
I am wondering why anyone would use anything but the stock “o” ring style seals on chevs. If installed correctly they seldom fail.
Thanks, Dave
