I normally target 180F, and in the summer oil temp can get up to 210F on the hottest days. The above link shows a sample screenshot with OAT at 17F. I am trying to figure out some ways to increase the oil temp going forward. I already have the oil cooler butterfly valve mounted on the back of the baffle. I have mine fully closed during the entire flight. When initially installed, fully closed meant about 90% closed. I thought the 10% open would serve as a safety buffer in case of a failed cable. However, i changed it so it is now about 98% closed. However, the oil temp still hasn't risen. Thus, i am wondering what my next best step is. At first i thought that the vernatherm blocked all oil flow to the cooler when cold, but according to some searching, i read that oil is always flowing thru the oil cooler. The vernatherm controls how much oil bypasses the cooler in parallel. If this is correct, then i guess it is worth it to get the oil cooler door to 100% closed? It just seems more like my stock Lycoming vernatherm is adjusted too low for temps. Anybody replace their vernatherm for warmer temps? Also, how do you guys in colder climates deal with these issues?

    Sorry, I am not much help. I use the butterfly (100%) and don't have a problem getting it up to 180 on a 17 degree day. When I am running normal, my oil temp will go between 202 and 196. I am assuming that is when the vernatherm is cutting in and out. But don't really know for sure.

    Jae, although that temp is on the low side, because of where the temp is me asured, you may still be hot enough to burn off the condensation... and tha t's all that's necessary. I also have a personally built butterfly valve, and can adjust it according ly, and still can manage to get the temps in the 180's in the winter. Might try to block some of the exit area of the oil cooler???? --- On Mon, 1/14/13, Jae Chang <jc-matronics_rv10@jline.com> wrote: From: Jae Chang <jc-matronics_rv10@jline.com> Subject: RV10-List: Cold Wx Ops and Oil temps https://lh6.googleusercontent.com/-NbEa6c8c35s/UPRK4Cj9qsI/AAAAAAAAFFM/ZrZK kxB2UJc/s972/screenshot-20130112-190652-787.bmp I noticed on my last couple of flights with the colder winter temps, that m y oil temp is riding on the lowest range around 160 to 165F in cruise.

    Checking the Vernatherm is easy. Remove the Vernatherm and paint the cone all black with a Sharpie. Go fly. Remove the Vernatherm again and check for a silver ring on the cone .... caused by the cone closing up the hole in the accessory case. No ring? Get a new Vernatherm.

    As of 6 months ago, Aerosport was still building the engines for the -10, but the prices were significantly higher then what you can get a new IO540 for from Vans. I think the price was $56,000 vs $48,000 or so. Aerosport was very upfront about their inability to be competitive, but were willing to build one new or help find a good core to overhaul. David H [quote="dfritz(at)bpgsim.com"]If I remember correctly, early last year this list carried a discussion regarding Lycoming raising prices of kits to the level that Aerosport and others stopped building new engines. Thus it looks like that option is off the table. Aerosport has a great reputation among the members of my local EAA chapter. That is where I was going in about a year, but now I have to rethink my options.

I actually trust them very much and have had nothing but a positive experience from them. I get the feeling that they will bend over backwards and go further than they even should be willing to, to support your engine. They've sent me seals and gaskets that I should have paid for, for free, and things like that. Over and above. I can tell you that on my engine, my experience with those copper crush gaskets hasn't always been positive. It seems that over time those can be prone to leakage. I had a leak on the right side of my engine that was fixed by replacing the copper crush gasket under my oil pressure adjuster on the right side. Certainly this isn't absolving the engine builder from any possibility of improper torquing or a faulty component causing an issue...nobody knows what happened yet. But, I'm just saying, I think there are far more happy customers of this one than disappointed ones. If you really want an eye opener, read the Lancair list for threads on the Performance Engines (Continental models) that they have, and what kinds of issues they have. That can be scary. It will be interesting to see what was the cause on this one....valve cover gasket? Copper crush gasket? Oil return line? Could have been a bunch of things....could also be an automatic quick/drain.

Get a new > Vernatherm. > Linn Linn, i think i am having the opposite problem, though. No ring in my case would be good, as it would mean higher oil temps. I am just going by what ive read so far on these links. DanH has some great posts explaining vernatherms and oil pathways, etc. http://www.vansairforce.com/community/showpost.php?p=536959&postcount=12 http://www.vansairforce.com/community/showthread.php?t=45548 Also, from what ive read, it seems Vernatherms rarely fail, and if they do fail, they usually fail with oil temps too high. Also, I realize i should clarify my question a bit more. I can definitely hit higher oil temps at lower altitudes or takeoff with enough power and thus heat. On this particular flight, i climbed to 10,500 to 11,500 where power is down around 60% 20"x2300 rpm. I can see this sort of trend all level at 11,500 ft: at 30mins OT is 172 at 42mins OT is 170 at 43mins OT is 169 at 54mins OT is 165 all CHTs constant between 260F to 302F. Then i had a long 30 min descent where OT went down to 154F. Thus, one question i have is whether there is enough power or heat being generated by the engine at these higher altitudes and low OATs to even sustain higher oil temperatures? Maybe a higher RPM setting or higher fuel flows would help raise temperatures? During the summer, i normally run LOP, but i did add fuel flow to a peak EGT setting to see if that made any difference. Not sure i noticed much of any. Jae -- #40533 RV-10 First flight 10/19/2011 Phase 1 Done 11/26/2011 do not archive

    Jae, I flew 2 hours last week on a day at 20-25*F OAT. Mostly shooting approaches, so MAP was 12 - 17" much of the time. Oil temps were 180* plus/minus 5*. I would check your oil temp probe before getting into the vernatherm. Jim Berry N15JB Read this topic online here: http://forums.matronics.com/viewtopic.php?p=392283#392283

    I'm surprised you get 210 in the summer and can't get it above 165 in the winter with the butterfly valve. I have the valve too and also hit around 210 on hot summer days in climb out. In the winter mine is around 165 if I don't use the valve. If I close it it will come up fast and must be partially opened to maintain around 185. It is very quick to respond to inputs on the valve. ----- Original Message ----- From: "Jae Chang" <jc-matronics_rv10@jline.com> Sent: Monday, January 14, 2013 12:21 PM Subject: RV10-List: Cold Wx Ops and Oil temps > > https://lh6.googleusercontent.com/-NbEa6c8c35s/UPRK4Cj9qsI/AAAAAAAAFFM/ZrZKkxB2UJc/s972/screenshot-20130112-190652-787.bmp > > I noticed on my last couple of flights with the colder winter temps, that > my oil temp is riding on the lowest range around 160 to 165F in cruise.

    Ditto here too. Have run the valve for 300 plus hours same results accept little problem staying below 190 with valve open in summer.

I have had my valve on for 3 years and same results as Sean just posted. It works really good.

    This thread reminded me of something. Years ago (decades actually), I knew a mechanic who swore by running two quarts lower oil quantity as a baseline in winter than summer. I never thought it completely through because I was just a renter in those days, but it might make a difference. -------- Myron Nelson Mesa, AZ Emp completed, QB wings completed, legacy build fuse on gear.

    Subject: Oh no, another new guy...
    Greetings all! I am embarking on this madcap ride known as aviation and the RV-10 is at the top of my short list. I'm fast approaching middle age, have wanted to fly since I was a child like just about every one else who gets the PPL. My wife is finishing up her Master's degree, and when she's done, I'll be jumping into getting my PPL. I live in San Tan Valley, AZ... a southeast suburb of Phoenix. After checking the Van's site, I was hoping to find a Van's club in Arizona, but they don't list one. Any builders/owners on here that live in Arizona? I would VERY much like to hook up with you to take a look at the aircraft in any stage of completion. I drive all over the southern part of the state, so pretty much anywhere from Phoenix south to the border would be withing my driving range. I also get up to Pinetop/Showlow on a semi-regular basis. I'm a very hands on person, started working on cars at 15, was into drag racing for several years, and have been a field service tech for over 20 years now. Building my own plane seems like the ultimate adventure! I'd love to hear from anyone in the area (or anyone in general!) about the RV-10, and GA in general. Cheers! Ron
