some of you are familiar with my 1954 235 inline 6 in my 1951 chevy 3100. for those who dont, it was recently rebuilt, about 8 months ago, and after doing way too much tuning and adjusting (the guy who rebuilt it did nothing adjustment wise) ive discovered that i have a leaking exhaust valve somewhere. i did the ol' dollar bill test on the exhaust and sure enough it was being sucked right back in. im very positive a valve isnt burnt or broken, i believe there is most likely a bad valve seat. does anyone know how to fix this, or if it involves tearing down half the engine, will it hurt anything over time?
