I have an
oil leak at the rear of my 428 that was not there before. I replaced my old 71 cc heads with some new 69 cc heads canton pan windage tray and a set of roller tipped rocker arms. It appears that it is coming from the fly wheel area. I did not change any thing in there however. This is an older car built in 1993 I have had since construction about 7500 miles on it.
