Recently, I had to change my oil cooler, as my old (plated) Revmaster oil
cooler had cracked. Not wanting to wait a week for shipping, I went to Auto
Zone and bought a Tube/Fin design, and for all intents and purposes, it fit
perfectly. Nearly the same size as the Revmaster, so all I did was zip

Sorry, I disagree, imagine that. Particularily since the comments about the
sensitivity of the KR are not about it's ground handling. When my first KR
was a retract, and converted to a fixed gear, Grove type, which was more
narrow than the retract, I saw no difference in the ground handling. The

I replied to this question, this morning. Let me further qualify what I
posted with some experience.
My first KR started with an 1835 Gilbert Duty conversion. It had the oil
cooler on top, in the exact same location where all the GPASC VW engines
have theirs. I later converted that same engine
Our 1835 VW had some long hoses to the oil cooler mounted under the engine,
behind the carb. Putting on the Diehl nose gear meant moving the oil

Actually, I am planning on getting my cabin air that way by putting another
inlet on the opposite side of the cowl. But I am going to fly this thing
first and do that later.
Mark,
I hope you are planning on flying in the winter time. KRs get very hot
inside on a sunny day.

I have not been able to get to the plane decently for better than a month

Bill,
My only thoughts about your oil cooler/filter combo is that are you in any way
changing the routing of the oil flow through the block? Most engines I have
dealt with pump oil first to the main bearings to protect the crank, and then
"back up the pressure" through the oil filter and then u
