Lew Gage is a retired airline pilot and A&P mechanic who knows more about operating early E-engine Bonanzas than Warren Buffett knows about the side streets of Omaha. And he's written much of it down -- as a regular contributor to the American Bonanza Society magazine. Gage has published a book of his articles (E-Series Bonanzas-available from ABS); and it includes guidance on a variety of issues. Take, for example, what he has to say about preheating. Just hosing down the cylinders with hot air isn't nearly enough. It's the oil that counts when it comes to thawing out a frosty engine. Gage wrote: "During oil preheat, the rest of the engine will also become heated, however, heating the cylinders by blowing hot air over the top of the engine may take the cylinders down to Miami and leave the oil up in Minneapolis."
