My front seal on my 22RE doesn't seem to be effective it is the on that is
located behind the main pully I think it is the timing chain seal, it is
round with a spring in it much like the rear end seals at the tires. Does
any one know why it is being a problem. It has gone twice already since I
repaced my motor last year and it went in my other motor also. Makes a
horable mess any hints how to make it better or prevent it from leaking.
Thanks in advance Derek Luymes.

Derek,

You have found one of the few inherent problems with these otherwise
great motors (actually a lot of Toyota motors are prone to this). I
suspect that the sealing surface (where the crank seal actually mates
with the crank)on your crankshaft is what's called "seal worn." This is
where the seal has actually worn a groove into the crank snout. This is
easily repaired with a sleeve that should be available locally at any
decent auto parts store. Most vendors call it a "Reddi-Sleeve."  A
little trick I use when installing seals like this is I smear a very
light coat of Permatex 2B (the non-hardening stuff) on the OUTER edge of
the seal. This will assure the seal does not leak around it's outside
diameter or will not pop out at a later date.

Brian I haven't had that problem. I will tell you that when I put in a
new timing chain a few months ago, The parts guy at the toyota place
gave me a new crank seal that wasn't as deep as the old one.  This means
that the new seal is not in the old groove, hence----no leak.
(Hopefully.)

hope this helps,

Repalcing the seal is a simple procedure. When you install it use grease to
make it seat evenly I usually tap it lightly with a rubber mallet. Make sure
that also you replace the pump seal. I usually help this one settle with some
sylicone so it will remain where it belongs if it doesn't it could leak too.

Hope this helps

I believe when I had mine replaced a couple years ago, the mechanic
installed a sleeve on the shaft to take care of the worn shaft area
where it mates the seal.  You might ask you local shop about this.
