Old Gaskets:

Is there any way to rehydrate old composition gaskets? I have several gasket sets I'd bought in the 70's and don't really want to unfold them without adding some humidity first. Fel-Pro used to fold and rubber band long gaskets in the middle over a tubular piece of cardboard to fit them into a shorter box. I've used a portable steamer to soften them in the past, but my wife won't let me use her new one for the purpose.

Any ideas?

Thanks,

Rob

I've soaked cork gaskets in the bathtub. Could you soak them with oil?

The back of the can of Gaskacinch says that it rejuvenates gaskets.

Mike are you telling us you don't use the dishwasher to clean parts?

Rob,

I saw a restoration article that said soaking overnight in phosphoric acid would clean and rejuvenate cork gaskets, never had to try it though.

If you want to steam them, how about an old clothes iron ?.John

Hi John, a 5% concentration of phosphoric in a squeeze bottle lightly saturating a cork/rubber composition gasket will work wonders on it's pliability. I'm particularly interested in the paper/oilcloth type that was used on the front engine covers and oil pans that were typically a light gray, and off color red or peach that was common with all manufactures back then. These were die cut and can be remade by hand if necessary but if these can be saved/used, would save a lot of time. Steaming old gaskets such as these does work well but one needs a steady, soft, and consistent steam as it takes a little pressure to unfold the gasket as the steam spray is aimed in the area of the bend. These gaskets are can be very hard and brittle in the areas they are folded over at. I've not tried to unfold these because didn't know if there was another way someone else was familiar with. I learned the steam trick from an in-law that worked for Fel-Pro in Skokie, IL several years ago. He ran a die cut machine to punch gaskets out.

It is difficult to obtain these any longer without modifying the engine for their replacements such as scoring the heads for head gaskets. I had an oil in water and vice versa that rebuilding the oil cooler corrected, (thanks Glenn) on the B67, and would like to pull the pan to get a look at the bearings and such. I realize I could purchase a new gasket for the pan and not have a problem but these are readily available if usable.

Thanks,

Rob

Rob,

What about removing it from the box and misting with lite oil, like Marvel, then waiting to see if it springs out of the folded position on its own ?.Shouldnt effect sealing since the gasket allready is ( was? ) lightly oiled.John

I'd never really thought about that. I have a little atomizer/mister that could be used to not saturate the substrate material. I may give that a shot on some other gaskets that don't have a use any longer.

Thanks,

Rob

You may think about soaking it in some water with viagra mixed in it.

I don't know. That would prolly just make them harder for longer than they are now.

Oh your supposed to take them by throat? My DR. did not explain that no wonder they did not work and hurt so much.

I heard "take 'em too slow and you get a stiff neck" ! Was this about gaskets ?
