KR> VW engine oil temperature

[Jeff Scott]

You guys can use aviation grade parts as well. ?Positech Oil coolers available 
through Aircraft Spruce are a good buy. ?$165 will get you a good aviation 
quality oil cooler that will address high oil temp issues. ?I installed one of 
the Positech coolers on my SuperCub clone. ?I make a lot more heat and have a 
lot less air flow to work with, but it keeps the oil temps on my O-320 nice and 
cool. ?I would think the oil cooler intended for either the O-200 or a Rotax 
would work quite well on a VW.

Here is a link to the Mocal cooler that I am using. Not cheap but quite 
effective.

KR> VW engine oil temperature

Sid, 

I used the fins on the bottom of the case to help cool the oil. Not sure how 
much it helps. IMHO, full flowing the oil and a quality oil cooler are the most 
important factors. I tried numerous things early in my flight testing period to 
keep the oil cool but changing to full flow and a Mocal 13 row cooler (from one 
of those stamped pieces of crap) took my oil from 250F to 190F. Oil temps are 
the nearly the same if I am in a climb, cruising to a destination or full 
throttle for 2 hours during a race. 

I am currently reworking my entire cooling system and will not flow air across 
the bottom of the case. I don't feel that its worth the effort.

KR> VW engine oil temperature

Revmaster makes the perfect oil cooler for the VW.  I used it on mine and if
there was a problem with it, it was that it kept the oil too cool at times.
Check it out on the revmaster web site or in this video on UTube:

You will get a very good look at the entire installation.  I did not just
think about it.  This was about my 4th attempt to get the oil cool enough
and this time it worked perfectly.  None of the others made much of a
difference and they were very "hokey".

Has anyone considered or is it possible to add or enlarge the oil cooler on
the VW to add 2 or 3 quarts capacity to give the oil a chance to cool some
before re-entering the engine?  Oil is major component in engine cooling

chance to cool some before re-entering the engine?  Oil is major

Appreciate all the commentary and suggestions.
I think I have a reasonable bracketing on various recommended temperatures 
except for the oil temperature (251 F).  The newness of the engine may be 
contributing some extra heat.  Another factor could be the prop: I don't 
know for sure if the Sterba 52X52 prop is right for my airplane.  Might be 
lugging to much and producing more heat and less power.  I will have to play 
with the engine tuning for next flight.
My plan is to keep the existing oil cooler setup.  Added will be to blow 
some fresh air on the bottom of the engine sump.  The sump has cast ribs and 
some tapped holes; just the thing to fasten some sheet metal.  I saw a 
baffle arrangement on a KR website, but cannot find it now.  I remember how 
that looked and can adapt that baffle arrangement to my VW installation. 
Also means yet another mod to the cowl and even more down time.  Gotta do 
what you gotta do.
Does anyone have any info on cooling the VW oil sump?

Sid,
It was made known to me long ago that running your oil temperature lower than 
212-215 degrees F precludes the natural elimination of condensation and 
hydrocarbons from your oil thereby shortening your oil's service life and 
actually HARMING your engine by retaining fluid contaminants in the oil.
The closer you can keep it to that 215 degree mark the better, but lower than 
that is just as bad for your engine, ...in my humble opinion.  I was also 
informed that organic based motor oils (standard motor oils) are able to 
withstand temperatures far greater than 250 before they start to degrade.  The 
number provided to me was almost 400 degrees F before degradation and coking 
begin to take place.
