Thumbs up Oil pump leak....fixed I think.

Hey gang...took the timing belt off for the third time in 3 months. I got the dreaded oil leak out of the front crank seal.

Here goes.

Take it apart down to removal of the timing belt.

take the belt, and all the idler pulleys off

Wrestle with the key on the crank that keeps everything in line

Pull the oil pump, 7 bolts, pop it free, lots of oil on the floor...

inspect....here's where it gets interesting. First off I laid it face down on the table like the guys at Ann Arbor, MI Subaru said to, There are 5 counter sunk screws holding the assembly together. ONE had backed out (it was still threaded, but it was backed out) the ones to the immediate left and right of the backed out one were very loose (like no effort to loosen type loose) Cleaned the backside off, lock tited all the screws in to not have to do that again. I bought two new seals. there's a small one that goes between the block and the pump in, the second goes on the crank.

The crank seal:

When seals are installed, there's usually a little bit of press involved with the seal I was able to remove the old seal by sticking my finger in the hole and just picking it out. Seals are made as a ring of metal encased in rubber or nitrile or some kind of soft stuff. The metal on the old seal was exposed and the seal was worn down through the first sealing lip. There was also wear on the back of the timing belt drive cog (the main toothed pulley that connects to the crank) The NEW seal I bought was a different part number that ended in "030" instead of "010" I'm guessing it's a different revision. The seal material is different. So, I put the new seal in (it pressed in just like it should have, threw a little red grease on the inner lip. You don't want dry seal riding on the crank at startup. I high temp RTV'd the back of the oil pump (there's no gasket between it and the block), and reinstalled it.

I should know today if it still leaks or not.

BTW, my house looks like the fram oil filter commercial. Big greasy handprints everywhere (the refridgerator, the kool-aid pitcher, the

Plug for me:

I lost my job last friday. My wife and I are moving to Atlanta, GA because of her new job. I can move immediately if need be, so if you know of anyone who's looking for an engineer/mechanic let me know.
