Safety wiring oil filters?

Aviation oil filters have safety wire tabs. FRAM HP filter, which for various reason are what I need to use on my VW based conversion, no got. Oil filters typically go on finger tight. Losing your oil filter could ruin your WHOLE day. You're right that losing one could ruin your whole day. My question is: "How many automotive oil filters do you know of that have fallen off?" I don't know of a single one. I was on a long road trip in my 1979 Camaro when I happened to look under the car during a rest stop and spotted oil dripping. My filter had backed off. Hadn't fallen away, but it sure wasn't sealing. Ron Wanttaja Interesting... I had a small oil puddle under the Blazer a while back. Since it was right after an oil change, I took it back and had it checked. Couldn't find anything wrong, but it hasn't leaked since. Richard |

Safety wiring oil filters?
The Rotax 912 series of aircraft engines use an automotive-style oil
filter, and no means of wiring. When tightened properly, they seem to grip more and more with use. My experience with automobile filters has been the same. I don't think they need wiring, but that's only my opinion. tom pettit |

Safety wiring oil filters?
I agree with Tom on this. I don't safety wire the filter because I think it
might come loose, I safety wire it because I feel better. It doesn't cost much in weight or time and it sure eliminates one possible, though not probable, problem. -- Stu Fields Experimental Helo magazine P. O.

I use an auto filter, I take a 3-or 4" radiator hose clamp (worm-gear type)and tighten it so that the back end of the screw butts up against a part of the filter bracket such that the filter can't un/screw.---This to be done just under the crimp -top- of the filter. NOTE--NOTE--NOTE-- casually inspect top of the filter for an extra rubber sealing ring---I Had it HAPPEN--the extra rubber blows out at the first appearance of oil pressure---It leaked out 4 of the 5 qts of new oil by the time I drove 9 blocks--luckily it was still leaking when I stopped and saw the trail. |

Some of the things we safety in aviation vs some of the things we don't are pretty interesting. For instance, we don't safety the AN fittings on fuel and oil lines. Why not? What makes these different from the oil filter? I've heard of it happening, although it never happened to me. Airplanes aren't like cars though, they have a prop which causes a LOT more vibration than the engine in a car experiences. That's why oil filters on airplane ARE safety wired. AN fittings are different from oil filters, they are a lot smaller and you really crank them on the threaded fittings. They don't have the same mass as an oil filter and because they are flexible, they don't experience the same vibrational frequencies. Or at least that's my take. Corky Scott |

You haven't driven much on "salt belt" highways, eh?? Washboard/frost-pocked roads are rougher than a LOT of aircraft! I live in Vermont Clare, we call that stuff "frost heaves" and what we have here is legondary. I've seen guys dent their roofs from being bumped by the frost heaves. Imagine mile after mile of close together speed bumps. But that kind of bumping is not like the frequency at which a prop vibrates. Whole different thing. Besides, folks slow down for them, or loose their suspension. Or at least that's my take. Corky Scott |
