[JM 35 Sedan]

I had a similar situation on a '35 coupe that I bought couple years ago. Even though I already knew the engine ran good, I decided to pull the complete engine so I could check everything over internally, and thoroughly clean the engine inside and out. After taking the pan off I found out that this was an LB engine that had been rebuilt years ago (0.030" over) with little or no wear ridge at top of cylinders, all bearings and journals look good. I plan to do the cleaning and put everything back together with all new gaskets. By the time you go through the hassle of just removing the pan, you could have the complete engine out to check and clean everything. JMO
