rear main seal on a 351m in a 79 Ranchero is it split type or solid
Does my 79 Ford Ranchero Gt with 351m
and fmx transmission have a split type or
solid rear main seal in the motor
Should be split according to Fel-Pro and Rock Auto.....https://www.rockauto.com/en/moreinfo.php? pk=123908&cc=1136876&jsn=473
Split type, and it would likely be neoprene. The other type was the split rope seal, that would have a pin to prevent the seal from spinning. The neoprene did not have that pin. I'm certain that by 79 they were using just the neoprene type seal with knurled cap. A Ranchero forum link for you: http://forum.grantorinosport.org/ranchero-forum_forum33.html
Yup, Ken it is neopreme.
