Bob, you should check your crank case vent hose on the top of the engine.
It goes from the black plastic crank case vent tower that is to the left of
the alternator, over to the intake air boot. Many times these are kinked
or collapsed and that can cause high crankcase pressure that will push oil
out of the weakest place which is usually the rear main seal for some
reason. The other thing to do is to smell your oil. If it smells gassy at
all, you should have your fuel injectors cleaned and checked. If you are
experiencing high gasoline consumption or gassy smelling oil, you could
have gasoline diluting your oil which will cause it to leak past a brand
new seal. They are made to hold in oil, not gas. I would also check your
oil level. I high oil level can cause leaks. I usually keep my oil level
between the two marks on the dip stick. Don't fill it all the way up, keep
the oil in between the marks.
What weight of oil are you using? If you are using synthetic, switch to
normal. If you engine has over 50k miles on it, I would also use 20/50
weight oil even in the winter. If you do all of these things and still
have a leak, then you are going to need to pull it apart again to see what
is up. Most of the time you can fix this problem by dealing with one or
two of these issues. They are cheap and easy so it is worth a try before
ripping the tranny or engine back out.
Let me know if I can help you further.
