    Rave valve belows

    I just rebuilt a motor and when I was pressure testing it the rave valve belows leaked. I don't have new ones handy so I put some 1211 on them and let them sit over night. Not sure if this is safe to do or not. I will test it again tonight when its good and dry and if it holds I guess its ok? Anyone tried this before? They are leaking on the lower end where the power valve stem sticks out.

    Well FYI they hold about 5 psi so no go. Anyone got some spares?

    You pressure test without the bellows. Make a rubber gasket, remove the RAVE and install the rubber under the housing.

    The RAVE bellows leakage is normal. No need to buy new ones.

    Well now I have another prob. I blocked the rave valves so thats good I still get a leak out of the cooling nipple on the head though. Am I supposed to block those off too? I think I am not. I have not tested the cooling system yet but I will tomorrow. And the book says I only need to do 5 psi for 3 minutes for both the engine lower end and the cooling system. If I put 10 psi in there could it have messed up the seals?

    Hopefully it is just a leaking sleeve oring between it and the head. I don't think 10 lbs could damage a seal into the water jacket area, as there are only orings and gaskets between each.
