Now back to the BOSS 302 block.... 331 stroker for my road racer, 12.5 to 1 engine, 7,000 rpm chip, rarely hit more than 6500 rpms......
I'm really tired of pulling the motor and replacing rear main seal.... gotta pull it for the third time now.....
Sitting and running,regardless of rpms, it leaks NOTHING, but get it on the track and after two or three laps,
oil coming out the bell housing, leaking all over the exhaust system and it looks like I got a 2-stroke motor under the hood.......2 different folks have looked at it and put in the rear main seal with the same result...
First engine was built with a factory 1969 302 block, when I took it down to freshen it up after 2 long hard seasons of racing, I decided to "upgrade" to the BOSS 302 4-bolt main block and have had nothing but headaches ever since.........never leaked a drop of
oil with the old block!!!!!!!!!!!!!!!!!!!
I used all the same components out of the other motor and they all went into this new block, that's the only difference from the first motor........the block, same heads/cam/intake/crank/rods/pistons/canton road race pan/same everything.............and I put the motor together the same way I did the first one!!!!!!!!!!!!
HELP, I'm using the standard factory 1-peice rear main seal as per Ford's directions, anyone have any ideas??????????
