Yeah the Ultra Black sealant states allow 24hrs for cure time. Just seemed a bit much. Plus with my busy schedule its hard to not have to go anywhere within 24hrs. I guess I will have to wait until I have some consecutive days off.lannvouivre wrote:You need to leave it alone the full recommended time or you might wash the silicone gasket off with oil splash and have it relocate into a critical area and plug an oil gallery. It probably doesn't take that long, but they give you that long period so you will not have problems, or worse, a catastrophic error like what I described.
