I just got my 91 xtracab back on the road after a lot of work and mods and it's still leaking a lot of oil,I replaced the front crank seal (number 2 )and still seams to be leaking from there.I know I saw a while back where there were 3 choices for front crank seals for the 22re a thin,thicker and thickest seal but can't find the numbers.I've used the one that came with the original timing kit then I used a NAPA 17758 and I think theres one more a very thin seal,the parts guys are not much help,hopefully someone hear has used it??

 

If you are constantly replacing front main seals because they keep leaking...

I would suspect a worn Crankshaft pulley/Vibration Damper.

-They sell repair kits, and some timing cover gasket kits are sold with repairs kits.

Or a replacement pulley is also available.

 

I never thought of that,I'm going to do some searching,Thanks So much Kiroshu

 

No prob.
