Care must be exercised not to get RTV sealant into the bolt holes when using it for application such as; at valve cover and transmission pans. If the sealer gets into a blind hole, it will form a hydrastatic lock and may prevent the bolt from clamping the cover. If the bolt is then overtightened in an effort to pull it down, damage may then be experienced, such as broken bosses on aluminum cylinder heads.
