I try to talk about all of the pros and cons to an engine build. As I said earlier when it comes to FE engines the rear main seal is always discussed. We do not have many that leak but every now and then we do. We have spend more time on
oil leaks and rear main leaks in the last couple of years than we have making HP. What I mean by that is that the HP is not a issue on these engines and the
oil leaks are. We have worked with all sorts of products and methods to try and come up with a full proof method but we still have not got one. If I put 100 engines on the dyno built the same way they will all make the HP they should but we will have a few that will leak. This is what I mean by spending more time working on
oil leaks. With the CNC equipement we use on the heads and blocks along with our years of racing FE engines the power is a non issue but that damn rear main seal is still lerking waiting to leak. It really sucks that is for sure. Keith
