KR> FW: Type 1 Cylinder Heads - cooling
While everyone is toying with extra oil to cool the heads. Don't forget, you would pull more oil from the sump. Which would leave less to be cooled. Leading to hotter oil, hotter heads.This is a bad idea. Period! The engineering to fugure out the amount of oil needed in sump, out put of pump, thermal shed, and so on, is way beyond anything worth doing for the amount of return.Power = temperature. This little engine is pretty much putting out all it can, and still remain reliable. NASCAR doesn't use Detroit engines from production cars. They are specially designed just for that class car and special usage.I don't want to seem like a poop. It's just how it is.Gary Hinkle. Corp, Cargo pilot, and seems like forever A&P.

Hi KR league,? of all the discussions that are so important about controlling heat, I am surprised that so little discussion of oil happens. This is a big decision. My research for my 1835 vw and oil has led me to Quaker State DEFY.? I am running the 10w30 and the API-SL class. This is a semi- synthetic with boosted zinc for anti-friction. In aircraft we can't use a full synthetic because lead in av-gas will destroy the anti-friction adds in the pure synthetics. Even if we plan to use mogas primarily, there may be the need to use av-gas all of which have high lead.? The molecule size in synthetics, even the blends, is smaller and is known to run cooler. Note:? Quaker State DEFY is in almost identical containers with API-SN class oil. (Strange).? SN doesn't have the boosted Zinc. You have to read the small print to get API-SL. The SN class has been made for the auto engines with catalytic converters because the high zinc has been known to ruin the catalytic converters. Since aviation does use them (yet), we can benefit from the zinc friction reduction. Hope this isn't noise on many of the great signals I read everyday from you pros.Cheers,Rene Ffrench N44774.

KR> O-200
Any of you guys with O-200 engine have knowledge of how to start up after rebuild? Is there a ?pre-oil? procedure? Thanks, Gary

At that price I would snatch it up if it was not on the opposite corner of the U.S. from me.

KR> Oil additives
I had a friend that worked for the city doing auto maintenance. Did tons of engine rebuilds on the police cars and he swore by Rotella. The fact that it is sold in gallon jugs so they are easy to fill back up to get rid of the old oil is nice too.

That goes for cars too. As I understand it, the metallurgy of auto engines changed in the 80s to be compatible with the mandated lower zinc levels in oil. So I suppose that means if you didn't give up your Bricklin to Cash For Clunkers, it would be wise to run Rotella.
