    As the gaskets are getting scarce, I wanted to make future searches easy for others. So I did a search on here and got 2 results. The first one was exactly what I needed (assuming Nick describes it right) - Paul's method of restoring the VC gaskets. I bought a set from him which have worked well since '12, but since I have motor open, I'm going to run this procedure on my original gaskets. I should thank luigisho too since he is the OP here . . .

    Can someone clear up the "Rislone" step. I assume Nick's referring to their standard Engine Treatment product? I see they make a high-mileage version which I may use in the crankcase once things are back together.

    Have you tried MG Chemicals Rubber Renue?

    I have also heard, but not tried 303 rubber seal protectant and conditioner.

    Not sure which Rislone product they were referring too. Since they are generic cleaners not directly related to rubber restoration. I know that agents are added to high milage oils to help keep rubber parts swollen for better seals. Laquer thinner is not good on plastic, it breaks it down.

    how come you cannot find new ones? sho source has them. If they are really bad id just rtv the head let it dry to give extra compression.

    2 reasons:
    Trying to save $$$, and
    Want to be prepared for the future when there are no longer any left.

    This cat did some work, but woulda been nice if he included the Nimz Method.
    Go straight to 13:20 for summary.

    I have seen another video before that showed using ATF vs 303 with a heat gun to restore plastic parts. I have never attempted this, so I don't know what the long term effects are. They claimed the results to be the same and long term. And like with the wintergreen, the parts became noticably closer to the original black color.

    I guess the jury is still out re: long term consistency. I'd even thought maybe the weather stripping could be restored. but haven't done those before so don't know if there would be other obstacles.
