[AJD] Antique-johndeere Digest, Vol 82, Issue 4

Tue Jan 10 11:28:51 PST 2012

My machine shop guru claims there is no need to put hardened valve seats in
any 2 cylinder engine, unless of course the valve seats need replaced
anyway.  Reason:  the hardened valve seats are only needed in high rpm
performance engines because the unleaded gas burns a little hotter, and over
time damages the valve seats.  Never going to be the case in the low rpm
engines.  He has rebuilt several motors for me, and all continue to perform
without flaw, without hardened valve seats.  His recommendations are
different with the four, six, and eight cylinder engines.

I believe that the issue of lead and engine valves is a myth. Amoco ( now 
part of BP) premium gasoline ALWAYS has been unleaded. I easily recall the 
introduction of the Oldsmobile and Cadillac overhead valve V-8 engines in 
1949. The largest and most powerful previous engine for Oldsmobile was 
straight-8 used from 1937 to 1948 inclusive. Not considered high performance

nor high compression. The V-8 was, relatively speaking, a powerhouse. Owners

seeking the best from the engine often used Amoco Premium- unleaded. Amoco 
even often pictured the Oldsmobile in their ads. I knew some owners who used

the Amoco Premium exclusively. I never ever heard of valve problems 
resulting and some of those cars were driven very hard.
