since im swapping flexplates tomorrow, o bought an additional rear main seal just in case. Fel-Pro now makes a PTFE (teflon) rear main seal. it is supposed to last longer than the rubber. it is build different than the rubber. the rubber uses a spring to maintain tension on the crank where the teflon just uses a stiff lip to keep pressure.

if you got the 2 piece rear main in that 351, I would say its not worth it.
for a one piece the PTFE might be the way to go.2003 Town Car Signature - 3.27 RAR, Dual exhaust and J-mod - SOLD 9/2011

yup, you gotta pull the tranny, converter and the flexplate. jam a screwdriver into the old seal and pry it out.Originally posted by 1987cp View Posthttp://secondhandracing.com/Home.aspx
