Cracked Oil Filler Tube

mquam99 · #1 11-07-2011, 10:33 AM

Over the weekend I was installing the baffling for my io-320 and noticed there is a crack in my oil filler tube. It is not noticeble unless you twist the tube like you were trying to remove it. My questions are this

1. can I seal the crack with something (JB weld, proseal etc)
2. Is replacement a better idea
3. any suggestions on removal, my tube is well secured at the base

thanks in advance

might as well fix it correctly now....later sucks.

I agree with you.. One question, looks like my engine builder installed the tube with a sealant to keep it from going anywhere.. the sealant is red in color

any suggestions on how to loosen that sealant to remove the tube??

Just a couple of thoughts - if you do a temp repair, there's a chance you're going to wind up stranded somewhere. As to the red stuff, hopefully it's not RTV - but a little hard to tell you what it might be.

In any event, take some care removing the tube: a) you don't want to break it off near the base with some of the threaded portion still in the engine case and b) you don't want plastic and / or residue from the sealant dropping into the engine.

trying to remove this thing is an issue. It looks like the gasket was attached to the case with some adhesive.. its red in color. the tube will not budge at all. At this point I have to remove this and replace it, but no luck at all so far.

I am thinking some heat might help but not sure at this point

any other suggestions?

Are you sure it isn't safety wired to the crankcase? Mine is.

The tube is not safety wired at all. It feels like the gasket was glued in..

Here is a photo of the tube. you can see the red sealant on the gasket

looks like locktite red. apply a little heat to the case area and it should loosen up.

OR call your builder and ask him, what it is? and how to remove it?

Is this a certified engine? if not, just make you a new one... been done many times. JB weld has also worked for many for 1000"s of hours, plastic... not a lot of stress here if you wire tie tight at the base.

Buy a new one? Well, bend over!!!!!!!!!! BTW... it should be wired...
