I am building a 2056 for a friend and it is mounted on my run up stand and fires right up as expected but has a serious oil leak on the 3/4 side . Not the filter ,not the oil cooler, not the pressure switch. I replaced the push rod tubes and installed Vuton O rings. Oil is coming from above the air diverter plate above the pushrod tubes . The diverter plate is filling it's pockets with oil. I removed the plate and see no Leake.I removed the spark plugs and turned over with the starter motor and got 25PSI {I have a direct reading guage installed) can see no leaks . When running I'm pumping over 50PSI . NOW I NEED SOME HELP .Can the small "freeze plug in the main oil passage be leaking? I have NEVER had a plug leak and with checking some other builders including my Son who has built many T4 s for his own race car and many others . If this is a problem can I repair with "JB" weld? Please help, I hate to have to take this apart and start over. AL

I think we found the oil leak problem . One of the cylinders is seeping oil out between the bottom (case side)two fins . Not the sealing gasket to case . Anyone ever seen this . AA cylinders. seems like the cylinder is cracked on the bottom because we removed the tin and the top and sides of that cylinder are dry.
