F-head Engine Gaskets
 

I am reviving my new to me 64 CJ5 that has been asleep since 1976. I am
currently changing all the fluids and everything rubber.

I have rebuilt engines before, but not of this make or vintage. I am not
planning to do all that much rebuilding since the jeep has less that 9,000
original miles on it just replacing seals & gaskets.

What is the trick with the round rubber strips on either side of the rear
main bearing cap? The manuals I have been reading indicate you do not trim
them, but the amount that they protrude is critical.

Also are there any other tricks unique to the F-head that I should look out
for?

Re: F-head Engine Gaskets
 

Many older engines sported rope upper and lower rear main seal halves, which
had to be trimmed to protrude a fairly exact length. Replacements tend to
be preformed rubber, which you do not trim. I have never disassembled one
of these engines, but I assume it is the same.
