Ridge Runner 976 Report post Posted May 8, 2022 It is common for the ends to leak if you use the cork gasket ,a bead of silicone is best there and do not use the cork . If it is pooling beside the carborator it could be leaking from a valve cover gasket ,do you have a PVC valve ,if not it will build up pressure in the crank case and blow out gaskets and front and rear seals .

Vicfreg 616 Report post Posted May 8, 2022 Like RPM suggested, make sure you have a good PCV path. The PCV hose connection on a basic Holley is under the rear float bowl. Quote Share this post Link to post Share on other sites
