Any Solutions to 55/56 Hood Oil Canning
I guess in 1956 these trucks didn't cruise at 70 mph, so the hood oil canning was not an issue. Wanting to reach out to this community to see if anybody has come up with a solution?
I did find this solution and maybe able to fabricate a similar brace. http://67-72chevytrucks.com/vboard/s...541132&page=21 (post 506) But, wanted to find out if there are different solutions for this issue. Thanks folks. |

That's a pretty heavy chunk of iron to hang on a hood. I had a 57 Panel with a hot 327 that I drove hard and didn't have that issue with so I haven't experinced it.
I'd agree that a brace with maybe some dense foam pads between it and the bottom side of the hood should keep the oil canning down. |

Never had any oil can with mine. Someone did something to stretch the metal with yours to have that happen.

What about Berliner or lizard skin on the underside?

Re: Any Solutions to 55/56 Hood Oil Canning
if you look under a newer vehicle's hood you will see they used a sheet metal stamped brace and took up the gap between the brace and the hood with some adhesive like seam sealer, some have a foamy looking stuff in there that foesn't stick to the hood. a dab here and there. you could use some wax paper between the hood and the adhesive so it doesn't actually stick to the hood and then there would be less chance of distortion on a hot day. even some spray foam insulation would likely work then, a little dab here and there.

Bosco, not nearly as custom and sexy as Stepside Jim's by any means, but I posted previously about my approach. I bought a 57 Bel Air hood center brace (Eckler's 57-211495-1) and modified to fit mine. I wanted it to look like Chevy should have done it. Cut to required length, fab an "L' brace for one end, and nutsert on the other. I will be adding the standard stock foam isolator strip between

Re: Any Solutions to 55/56 Hood Oil Canning
If yours has that brace going through the middle of it, (I don't know those trucks well) then just try putting a piece of cardboard or something between the brace and the skin and see if that stops it. If it does then a piece of plastic or tar paper or something like they originally had may do it. I have had hoods do this where things have just over the years changed a little so the gap is increased just a hair, one 1/16" piece of rubber and it's gone.

whatever you do bosco DONT use expanding foam behind a brace if you decide to ad one...you put a brace in there and squirt expanding foam behind it then your gonna have a big hump in your hood....they do make a non expanding foam ....but.....

The solution offered by bowt1ed is a good one. I would go one step further and use an adhesive caulk to bond the hood to the brace. A few well placed daubs of Sika-Flex on each side of the brace and you'll be good to go |

Received my brace and wanted to ask which end did you remove? There are two different levels of bends. A slight bend and larger bend. Looking at your pic it looks like the larger bend was kept and mounts to the back of the hood, but want to confirm. Second question, did you have to tweak the brace much to get it to fit? With he larger bend mounted to the rear of the hood it will push up against the hood. Thought I would ask before I go bending this brace. Thanks, Russ |
Re: Any Solutions to 55/56 Hood Oil Canning
Russ, correct. I attached the end with the deeper offset bend at the rear cross support with a nutsert. It fit like it was meant to be there. I cut the end with the shallower offset bend off and welded a 90 degree plate that slides under the front brace/bracket, drilled a couple of holes. Although, the rear is a bit closer than the front, mine doesn't press against the hood. If yours does, you might want to try the other end.
Cheers, Jim |

Re: Any Solutions to 55/56 Hood Oil Canning
apache hoods came with the brace down the center
it still flexes quite a bit anytime you get much over 80 mph :D |

Finally was able to install my fix for the hood oil canning. Appreciate everybody's help and ideas. Here's the final solution. Fits right up against the hood, used some dabs of silicon along the way to provide some vibration dampening.

Re: Any Solutions to 55/56 Hood Oil Canning
Right on, hopefully what you dabbed between them stays flexable. From the factory they use a soft foam because if what you put "glues" the two together you will end up with a "ghost line" on the top that you will be able to see.

Re: Any Solutions to 55/56 Hood Oil Canning
Thanks. It fit really well. Yes the silicon is a soft when cured. Didn't use that much, just enough to eliminate any vibration.

Cool!
