Need some advice please. After putting this engine together, l have pressure checked rotory valve chamber, and the cooling system. There were no leaks. Then i pressure checked the upper and lower engine chambers together. There is a small leak from the rotory valve cover. I removed the cover. The case halves have a small step that l feel with my finger nail where they join together. Has anyone seen this before? There is no leak between the case halves. Can i just put some Threebond on the rotory valve cover oring? Or is there something seriously wrong?
