Posted: Sat Nov 18, 2006 8:36 pm Post subject: Oil Filter Cooler

Is anyone still using this list?  I have a question.  Has anyone tried

putting cooling fins on the oil filter to help with summer time oil cooling

problems?  I purchased some clamp on fins from J.C. Whitney a while back,

but haven't ever installed them.  Just wondering if anyone has tried this

and if it did any good.  During July and August here in the south I have to

watch my temps pretty closely and keep the cruise rpm down a bit.



Thanks,

Hey Jim,



Yup, I'm still here.  I was wondering about those too.  I thought my

cooling was perfect but after moving to TX, I found it was on the edge

during the summer.  I opened my inlet more and that let me fly thru the

summer but I still had to step climb to keep it cool.  I hate to go with

an oil cooler so I'm interested in any options.  I'm hoping that a new

cowling design will do it.  Maybe the larger oil pan from RAM?  Maybe an

air duct to the oil filter in addition to the fins?  Maybe an oil cooler

is best, we'll see.

Hi Jim,

    Yes, I did the very same thing with no effect, though the ones I used were small.

  Jim, I live in Longview, Texas, as you may remember, and flying in the high nineties is a regular thing in the summer.

   

  My oil temp rarely exceeds 190 degrees now. I haven't seen it reach 200 in over four years even in the hottest weather.  I attribute this to two things.

   

  1. My muffler is totally wrapped in a heat muff with air pasing over it all the time. this alone will reduce oil temp by as much as thirty degrees.

   

  2. I have an adjustable door/window in the cowling directly in front of the oil pan...and baffles on the lower cowl along either side of the oil pan to direct flow. In the winter I have to close it to heat the oil and warm up more quickly. This door is simply a square piece of sheet with an angle added on the lower edge for  handle on  the inside to slide it up and down. It is through bolted with little round head bolts...one on each side to hold it at one of three settings: wide open, medium and nearly closed.

Jim,



Yes I installed the JCW fins on my oil filter.

I also purchased the JCW remote oil filter kit. I now have my oil filter 

under the belly of the plan approx under the passengers feet. This kit also 

allows for an oil fitter that's twice the size of the wix filter that is 

used on a stock installation. This setup allows for very easy oil filter 

changes (I like that). Also with the large oil filter and approx 6 feet of 

oil line to fill I now run an extra qt of oil in my system. The location of 

the oil filter with the heat sink fins installed acts like a small oil 

cooler.

My oil temp is much more stable now under all conditions. My oil temps in 

the summer still run in the 215 - 220 range but like I said it seems to hold 

there better without a sudden up swing in oil temp if I climb. The stable 

oil temp really helps keep the water temps down also.

My installation has the exhaust wrap plus a heat shield between the muffler 

and oil pan, and a additional air scoop just below the oil pan.

Photos of these installations are available if you wish to see them.

BUT if I lived in TX I think I would opt for the installation of a small oil 

cooler.

<![if !supportLists]>1.      <![endif]>My muffler is totally wrapped in a heat muff with air pasing over it all the time. this alone will reduce oil temp by as much as thirty degrees.  

I had to remove the stock exhaust to get my oil temps anywhere near normal.  It was ceramic coated and wrapped, and I tried a simple heat shield that didn’t seem to work so I made both pipes go straight back into a single muffler under the belly.  That improved my temps a lot.  That was with an enclosed cowling.  Then I opened the bottom like the zeniths and that helped a lot.  I’d like to enclose the cowling again so I’ll be reworking everything soon.  I spose the oil cooler makes sense.

  Have you got plenty of airflow over the oilpan?  That's all it took on a

friends AVID.

Andy,



I have the Zenith scoop at the front of the cowl and I opened up some slots

on the bottom rear of the cowl to allow some high pressure air to flow

through and over the back side of the oil pan.  This helped some, but my oil

temps still run a bit higher than I'd like during summertime temps.  I also

wrapped my pipes and muffler with high temperature exhaust wrap that I'm

told is used on race cars.  That seemed to help the most.  The heat from the

muffler seems to be the biggest offender.  So, I can see where Gary would

have received a lot of help from moving the muffler to the underside of the

aircraft.

Jim,

     From my experience you have assessed this correctly. The muffler heat is the offender. If you have room to wrap your muffler in a heat muff with 1/2"  or so space, then duct air into it and out, it will do wonders. I use mine for cabin heat and it is plenty, as well as shielding the oil pan and blowing cool air over the muffler continuously. Like I said earlier, I recorded very significant reduction in oil temp.

   

  I made my muff with a small sheet of aluminun...rolled to fit and connected with a strip of nut plates. On either end I used semi-circular aluminum standoffs of 1/4" plate, like two "C's" butted against each other for a spacer to creat the 1/2" chamber around the muffler. Has worked great now for years.

   

  Earlier in the process I tried wrapping the manifold in exhaust wrap, too, but I didn't like that.  don

Yes, Jim,

     There are still some of us monitoring this list.  Not much action

recently.

     I've heard that the oil filter cooling fins do work.  I have no

personal experience with them, yet.  I plan to put them on the filter

on my Stratus when I get ready to fire it up.

List

  

     I began subscribing to the list about three  or four  months ago.  Thought the list was dead.  Good to see  others are using it.  I don't have a Stratus but do have an EA81 with belt  redrive in my Kitfox IV.  First flight was Aug 26 2005, Second flight same  day, engine out, off field landing, lots of damage.  Engine fired up and  ran smoothly two days after accident. Airframe is currently repaired and am  going over the engine/fuel sytem/electrical this winter. Aerocarb  Throttle body, Leburg ignition. Reductions belt redrive.   Haven't  positively identified the cause of the engine out yet but will work through  things over the winter.  Looking forward to more posts to get more  information on possible weak spots to monitor when I fly again this  spring.  Can't wait.

Two things to look for.

  

 1) The Subaru ignitor chip is notoriously feeble...You  really should replace this with a TP 45 module from NAPA.

 2) Did you have a valve guide failure?...It would be  unusual for this to stop the engine completly though.

when did the enigne die - climbout or level cruise?  full-power?  i ask 

because fuel flow can be an issue.  has fuel flow been tested on the 

ground at climbout attitude?  is there a three-stage fuel filtering 

system (course filter in tank, gascolator, and fine filters before 

carb)?  were gascolator and filters clean?  is there redundant power to 

the ignition (or computer)?  if not, there should be and if so, was 

backup power on or did it not keep the engine running?  how long was 

the engine running before it died?  was it very hot?  electricals can 

quit when hot then work again when cold.  is the alt working and wired 

correctly?  maybe it was running off of the battery until it died.



good luck, send more info so we can brainstorm.  also send to 

airsoob/flysoob and others can suggest things to check.  email lists 

are great for group troubleshooting.

Kelly,

Do you have a specific JCW number for the fins and remote oil filter 

kit?  I'd be very interested in seeing the pictures

of your remote filter installation and mounting.  This sounds like a 

really keen application.

Hi Larry,



Yes I still have the info & photo's, I'll try to dig it out for you 

tomorrow.



FWIW, I just re-installed my radiator heater last weekend, this time I made 

adjustable louvers to dump the hot air out the bottom if I fly on warm days, 

I'll shoot you a photo of that installation as well.



Have a Happy Thanksgiving with the family!

     Thanks for the advice.  I'm running  the Leburg (www.leeburg.freeserve.co.uk/)  ignition system.  Two magnets on a modified drive pulley on the crankshaft  give my ignition module timing and RPM data.  The ignition module then  tells the coil when to fire each of the plugs.  Advance curve is built into  the ignition module.  I found the stock Subaru electronic ignition finicky  and replaced it with this system early on. Seems to work very well but I will be  dualling the system from the coil on back before next flight.

     I had 50+ hours of ground running on the  engine before first flight and didn't seem to have any problems.  The  engine fired up and ran smoothly two days after the accident.  What would  be the symptoms of a valve guide failure?

Usually the engine will "cough" as it snaps off  chunk  of guide which then gets mashed in the combustion chamber.

  

 Engine stoppages have happened though, if yours just quit  without running really rough before hand I would suspect the ignition  system.

  

 Is it possible you had oil starvation?...Unlikely, but I  know the that some Soob motors have the oil pickup over an inch above the floor  of the sump and it gets uncovered duing climbout.

  

 Did you have fuel pressure at the carb when the engine  quit?

  

 Good luck...I know the feeling...I think I have just  trashed my new Lycoming...Wont know till I get the borescope test one next week  but I think I have...I feel sick..
