"For the Studes/Volvos and any others living in an unleaded fuel world we also use a lead substitute in the fuel tank to protect the non-hardened exhaust valve seats in our street cars until rebuild time when hardened seats can be installed."
Brian,
Been driving Studebakers since 1977, shortly after they were invented.
When the refiners dropped the lead content of fuel, I too, became concerned.
We put between 20,000 and 30,000 miles annually on our Studebakers. Have rebuilt several sets of heads in our engines. Yet to see or exerience valve seat recession.
Valve seat recession is a figment of the imagination. Like a balanced budget for the
nearly bancrupt U S A.
Real men use unleaded gas and they don't like ethanol.

I can only speak of the Saab V4 engines in the later Sonett's. They have
soft valve seats and they *do* recess from unleaded gas rendering the motor
useless. This usually takes around 25,000 miles of normal driving. Less if
you run the car hard. I burned up the valve seats on two motors so far,
fortunately I have a few more used motors to "go through" before I have to
start paying for hardened valve seats....
Ethanol is proving to be a MAJOR problem on the Saab 2-strokes. Higher
operating temperature scrubs the oil off the cylinder walls. We are
up-jetting our carbs and using more oil but engine seizures seem to still
be on the rise.
I hate ethanol.

Hey, Dan;
Studes are tougher then most. Our Volvos are blessed with soft seats as well, no figment there. I've taken older heads apart that were never run on unleaded fuel and they looked better then some 40k mile engines that have run the past 15 years or so. Just tryin' to be hepful.
Cheers,
Brian

I’ve put lots of miles on assorted Brit, Italian, and Swedish cars, and I agree with DD. Interesting, since I’ve never heard anyone else say this before.
