I got my plane in the air here just about 2 months ago and went to change the oil the first time this weekend. I was a little disappointed that the cooling duct as received with the engine has too small an area to get ANY of the equivalent oil filters in place. Early on I had noticed a small wear spot on the end of the Ryco filter and I put a small piece of tape in there to give some wear resistance. The issue is that all of the replacement filters are about 1/16" taller (or longer) than the original Ryco. Some of the filters are also about 1/8" bigger in diameter in addition to being just a little longer. This will mean rebuilding the front lower section of the cooling duct, of course after it has been all finished, painted and flying season is upon us.  I tried the NAPA 1394, Pennzoil, Wicks, Fram, Bosch equivalentsto no avail.

Install the oil filter. Trim the air-duct as needed for clearance. Put some
cardboard and tape over the oil filter to give clearance and than re-glass
the airduct. Remove it all when it dries and clean up the edges. My guess is
the air-duct was fitted to close or low. No big deal easy fix.

Don-
I just measured a Baldwin B33, and it showed 3.013" in height, if
that's any help.

NAPA Gold 1394, Fram Ph4967, Baldwin B33 all fit if airducts are installed
correctly. It is possible to install ducts too far down and create some
interference. You might first try repositioning your ducts to fit
correctly. If you cowl design requires the ducts to be out of position then
you will have to modify the ducts to fit.

Pete,
I do take offense to your assuming that I installed the cooling ducts incorrectly. There is only one way to install them since they come with the three cutouts for the 3 cylinders they fit over and the outside edge has to just slide over the valve covers to fit into place. It is like there is just 2 layers of glass to the wrong side of their mold. I guess I am just suggesting that Jabiru should take a look at their mold and give a little more clearance. Sure, it is easy and only 4 or 5 hours of work to cut apart, sand the paint off, reglass, sand and repaint, and I know this is what is required, I am just a little burnt over it! The other reason to post this is to inform others that are in the building stage that they need to take into account a little extra clearance is needed around the oil filter since all the replacements are bigger than the one they have in hand. I would have loved to have known this when it was dark 18 hours a day and 10 degrees outside when I was fitting the ducts and nothing was finish painted - no big deal, I would have added this to the list of little projects to get done before flying weather arrived as it has now.

Don,
Sorry if I offended you and I don't want to beat this to death but we've now
completed in our shop nearly 200 airplanes between Jabiru LSA's and
Lightnings, and a few other kit builts. We've supplied many hundreds of
engines and firewall forward kits to builders who have not reported
clearance problems. We've got enough experience to know that if the stock
Jabiru supplied airducts are installed correctly there is no clearance issue
with any of the oil filters we've used.
Contrary to your thinking there is more than one way to position those ducts
and they can be installed wrong. Once in a while early on when we were
still getting our build crew fully trained one of our crew would install one
a bit tight but reinstalling the duct correctly (and more training for the
crew member) solved the problem with little effort.
It is possible for a builder to widen out the ducts to try and make them
cover more cylinder fins or otherwise alter the fit. They can be squashed
down to a point where they don't fit. Installing the front air dam
incorrectly can pull the front of the duct out of shape. Any of these
things can cause a clearance problem.
You are wanting Jabiru to change a mold to make the installation goof proof
for the builder. I don't agree with that approach. The system works as
supplied if installed with the clearance Jabiru has built into their current
design.
