AIR CLEANER WING NUTS

[Jim Sullivan]

I remember reading a previous thread about air cleaners and the way to secure a dual quad air cleaner without the possibility of something loosening and falling into the engine. Recently I came across these wing nuts sold under the HELP! line. They have a wide flat base with a notch to prevent loosening. They are large enough that they would not be sucked into the engine. Once they are hand tightened, that notch really does a great job at preventing them from loosening. Sorry, I didn't get the part number off of the package. I could get if needed.

I put a dab of silicone on my threads and so far so good. Maybe I shouldn't have said that because now its going to bite me in the ass.

This the wing nut used by the 61 thru 64 Fords with the 3x2 and 2x4 aluminum air cleaners. They are available thru the Ford vendors.

Another easy method that I use is a 1/2" long piece of 1/4" I D rubber hose slipped over the thread area above the wingnut.

I would be just as concerned about water getting past that wingnut or any nut that secures a air cleaner cover,
I've seen 3 cars hydrolock from water getting past that nut. Whatever you do, place a flat rubber washer under the nut which will seal and also help keep it from unthreading.

How are you getting water up there? Open highboy?

I once built a BBC for a four wheel drive truck. The owner installed it himself and used a short piece of allthread and a nut and lockwasher to attach the air cleaner. After a couple of thousand miles, the allthread broke off where it threaded into the carb. The upper piece vibrated out of the nut and was swallowed by the #7 cylinder, where it knocked a hole in the head and split the cylinder. This highlights the importance of using the factory type stud with the flange that bottoms on the carb, if it's available. But I now always use a nylock nut on top of the air cleaner on my own engines.

no the most dramatic was a 40 Ford coupe with a full hood (louvered)and water ran in and sat in the depression around the nut on a 14" aftermarket air cleaner. since there was no rubber washer under the nut all thar water ran down thru the carb. The guy didn't know it, next morning went out tried to start it and bent 2rods when it hydrolocked.
