[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] Re: Missing Oil Cooler
Hi Jan, >>The V12 oil cooler is a weird beast; it only cools what flows through when the pressure relief valve opens. Think about it: when does it open? When the pressure is high, i.e., when the oil is cold, or the engine is running at high revs. In an elderly engine that maybe has to turn 2,500 rpm to get 60 psi when hot, there'll be precious little cooling. << I'm sure you know how to modify this as in Kirby's book. However. it's worth pointing out to others who own later model V12's who may not be aware that *all* V12 HE engines after engine no.8S44317 had full flow oil cooling, can't remember the year this was introduced. A tip passed on to me many years ago was to put a waterproof thermal jacket over the oil cooler in the winter months (bit hard to get at in a Jag !)
