Default Oil filler contacts engine mount.

I have an ECI IO-360 kit engine and a dynofocal II engine mount. The oil filler tube lightly contacts the engine mount ring. Has anyone here had an issue like that? What do you do to fix it?

From working on my Lycoming, I seem to remember there are a couple of filler tube lengths. Maybe you can find a shorter one and mating dipstick.

Plastic or metal?

I had a similar problem on my RV4. I could not find a short enough filler neck that would clear the mount so cut the one I had and then re-spliced using PVC pipe to get the appropriate length. I believe I used JB Weld and it's held for 29years. You'll need to get a longer spout to service the oil. Cut the stick and mark with corresponding marks for the oil level you normally use.

Cheers, Hans

I had the same problem on my Thorp. I purchased a long aluminum filler tube on eBay for $20 and cut it to the appropriate size and welded it together. Works great.

This is a common issue on Pitts. I recall that there is an instruction somewhere to check that the filler neck is good and tight, then take a heat gun and bend it slightly to get maybe 1/4" clearance.

Can't remember if the note was in the Eagle manual, an Aviat letter, or a Lyco letter.

Best of luck,

Wes

mine was the same way using the aircraft spruce dyno ring on the mount and a superior cold air sump. it didn't touch but was darn close. maybe 1/16". aluminum tube, we cut a section out, welded it together then shortened the dipstick accordingly.

Yea, there are dyno rings and there are dyno rings. I ordered a type 2 ring from Wicks for my IO320B1A and it was impossible to use. It would fit the bare engine case but interfered with almost everything else on the assembled engine. I had to cut the ring off the Piper PA30 mount and reuse it.

I'm hoping I can make my mount ring with a little clearance. I doing the ring from scratch per Pitts plans so I should be able to tweak the position of the ring tube to create a compromise between the filler neck and the mag. Since the Pitts ring uses smaller tubes than the ACS ring it should be possible. If not I plan to use heat to put a slight bend in the plastic filler neck.

Used ring from ACS, tube hit so hard could not screw it into sump. Cut tube just above the sump and reassembled with Mil-H-6000 and two hose clamps. Installed Adels at upper end for alignment and added security attached to baffle mount I think. Dipstick then contacts inside of tube. Installed clear vinyl tube on dipstick from under cap extending down 1" past contact area. It's long enough it can't come off. Can vary length of Mil hose to calibrate dipstick. Working great 14 years.

I just tried to heat it up and bend it a little. No luck. A slightly skinnier tube would be enough. I suppose if I have to I can have one made.

Not sure why there is the problem but we were ok with Angle valve on the Pitts and parallel valve on the Acro 2 with ACS ring.

I had to use a pitts ring on my Skybolt as well. Got it from Ravin Aircraft. I0 360-A1B engine. Clears every thing just fine.

I found this talking about the issue. I'll try again to heat up the tube and deform it

Heating with a propane torch did the trick. Thanks all.

''Real Gaskets'', the red reinforced silicone gasket company, sells a gasket for the Lyc filler necks. None of the factory gaskets seal very well and that area is a constant source of a weeping oil leak. The don't cost much so buy a few and give them out as Christmas presents.

When my oil filler weeped oil, I unscrewed it, put some Permatex Aviation Form-A-Gasket #1 on it, and screwed it back in. Now it won't leak, and won't come off until the next overhaul. But go light on the stuff....

Best of luck,

Wes
