Changing oil filter on a IO-520 with no mess
Author Last Post
I question the backwards rotation needed.  Someone makes a kit to make
the hole and a fitting , with tubing attached do drain the oil without
any dripping on parts that don't need it.

Thank you all for the suggestions. I do have the long Formafunnel but could not seem to make it work but the pics do explain a lot.
On another forum the same question was raised and several folks reported a method that worked without loosing a drop.
It involves punching a hole in the top of the filter then rotating the prop backwards 6 full revolutions. They all reported when removing the filter not a drop leaked out. My only concern was that, on my engine with the newer starter adapter that spring engages the starter when roated backwards, might do harm to the spring or starter.

I cut a standard 1 quart oil container into half - longitudinal cut.
Stick those two `tubs´ like a cascade under the filter.
Put some rags under it.
Control the flow rate by slowly loosening the filter.
Have some absorbing papers in the tubs to reduce the flow rate from first tub down into second.
Sometimes I get a couple of drips into the engine compartment - often none
 
After a number of oil changes I still have a mess. Tried the long Formafilter and cannot get it in a position that will work in my installation, IO-520 on a Seaplanes West mount.
It seems a remotely located filter would work the best and also not have to remove the lower cowl.
Can anyone recommend a one they have and like?
Thanks,
Tom
 
My filter also faces down at the 45 degree angle. I made a funnel out of a plastic auto trannie filler. Had to buy a second to make the right cuts and trim to fit after screwing up the first one. I work it down under the filter and  run the hose out the bottom, had to add an extra drain hose to get it long enough. Works great, never a drop spilled

I just use a double-bagged medium sized plastic trash bag with a wad of paper towels in the bottom. Work it up around the filter element and adapter from the bottom so it will slip back out, straight down when it is removed with the oil in it. Hang the bag so that it seals off around the filter and adapter as good as you can, it won't be perfect but almost. You can use tape or twist ties to hang it. When the bag is securely hung, unscrew the filter until the first gush subsides then continue to unscrew until it comes off. Once off, my filter will jamb in place and hold itself while it and the adapter drains into the bag, or you can go ahead and pull it out. I usually leave the filter jambed in place until it cools off since the oil is hot when I drain it. The filter stays mostly full of oil. When the adapter stops draining, I grab the filter with another wad of paper towels and pull it out then untie the bag and slip it straight down and out. There will be a few drips still coming out of the adapter but that can be caught with another wad of paper towels until you get the new filter back on. Good luck!
 
Thank you,
I looking at their website they have a long funnel thats 29" long that seem the best.
I'll take a good look next month when it goes in for annual.

 

I have done the same for a long time now.  The key for a no mess change is to not be in a hurry.  If you are pressed for time or need to get back in the air just suck it up and make a mess.

 

Here is my no mess recipe:

 

  1. De-cowl
  2. Drain oil from engine
  3. Cut safety wire on filter
  4. Place rags under the oil filter adapter at the base of the filter
  5. Place the form a funnel under the adapter and filter giving as much slope as you can.  There is not much depending on how your MP lines and/or primer lines are setup.
  6. Loosen filter until it just starts a slight drip at the base
  7. Poke a hole in the in the filter (top of the filter on the low side) with a long Phillips screwdriver to give it some air and burp it
  8. When the first rush of oil is over loosen the filter up a bunch more
  9. Poke another hole opposite the first one
  10. Let it sit for as long as you can
  11. Pull the prop through to burp it some more 

If I have the time I'll let it sit overnight, otherwise it can take an hour or two.  I do other tasks and inspections during this time.

 

I've made plenty of messes by being in a hurry and it seems like it take many hours of flying to get the last of the oil off the firewall.

For what it's worth, I just completed the annual inspection on a 185 with a Continental IO-550. 
I used a "Form-a-Funnel", and only had a couple of drops of oil to clean up.

Thank you for the input.
The engine mounted filter on my 185 sits inverted so it makes it difficult to capture the oil.
I am thinking id getting one of those "form a filter" setups. They come in longer lengths which might work.

Looking for 0470-u case mine has cracking at top of case

 
T,
 
My oil filter set-up is an Air Wolf and mounted different from yours.  However, here is my method to keep the "mess" to a minimum.
 
I used a 2-liter soda bottle and cut the top out to the extent where it can be slipped over the entire 48109 filter from the bottom up. I made a couple of simple hooks such that the soda bottle could be hung in place using one of the oil in and out hoses.  Now visualize that most of the filter is hanging inside the bottle.
Prior to hanging the filter in the bottle, i have broken the filter loose such that any futher un-screwing can be done by hand.
Then I use my fingers to unscrew the filter and let it gently drop to the bottom of the soda bottle.  This lets the oil lines and plumbing drip into the bottle also.
After the plumbing dripping stops, I unhook carefully the bottle and remove it, complete with the old filter and dripping oil captured inside.
Works for me via the AirWolf set-up. . . .
PS: I have a 1/4 turn quick (QD) drain on the engine sump with a short hose.  From the bottom, I force a longer, larger hose up thru cowl flap and capture the QD hose.  And that hose stands in a 5 gal. paint bucket on the floor.  Reach in an pop the QD into drain mode and let it dump the oil.  I do this with oil hot. The downside is not getting your arm burned reaching in to complete the dumping steps. D
 

I use this and it helps.

Hi,
Just did the first oil change on my newly acquired 185 with the oil filter mounted under the starter.
It sits about 45deg off vertical upside down.
I did punch a hole in the top of the filter and it drained for over an hour, engine was warm.
It still made a mess.
 
Has anyone found a good way to change the filter without making a mess?
