Default Oil Pump o-ring Location? and Cam Swap questions?

I'm 1/2 way through the a Delta Cams swap in my 00RS. The cams are in the mail as we speak. But.. I have a couple of questions related to the swap. I'm doing the timing belst and the seals, including crank, cam and the oil pump o-ring, etc.... My questsion are...

1. Where in the heck does the Oil Pump o-ring go? I found the water pump, and I believe the toothed cog to the left is the Oil Pump cog.. so.. where does the oring go? I have not yet tried removing anything to find it.

2. Is this stuff (LINK) fine for re-sealing the camshaft-cap to the head? I'm assuming it's fine.. but I thought I'd check with the experts.

3. Do I need to put anti-seieze on the threads of the bolts that hold the camshaft-cap to the head? I know they are not torqued high, but it's still steal into aluminum.

Thanx.

The oil pump o-ring is behind the oil pump.

That sealant is fine. Don't use too much.

No anti-seize necessary.

Pay attention to the oil pump bolts, three of them have a thread sealant on them. You should use thread sealant when re-installing them.

And the oil pump is in the center. The nose of the crankshaft goes through it. (the part the front crank seal is in)

Woh.. at the crank.. I never would have figured the pump was there. I was looking around the area of the oil pan. Thanx Hawk. I assume if I pull the whole pump, I'll need a new gasket there also? Or did subaru use a liquid gasket (permatex) there also? And now that I look closer.. I think that little puppy is the culprit of my minor oil leak. There appears to be a small stream of oil running down the seam there.

Hey Tim, when you say Thread Sealant, your not talking about LocTite are you? But rather some sort of sealant for bolts?

Thanx guys.

If I recall correctly the oil pump has 3 seals which you should replace while you are in there. the O-ring on the backside, the front main seal, and the perimeter of the oil pump which is sealed with a liquid silicone RTV type stuff. Anyone of these can cause a pretty good leak if they go.

Do you guys happen to know the proper torque spec for the oil pump bolts?

IT's made by permatex. Any sort of non hardening sealant should do the trick. You'll see what I mean when you remove them. I think it's called permatex #2 non hardening sealant.

When I removed the oil pump, I found that 2 of the bolts had something on them. I assume the sealant your talking about. But not 3. Are you sure it wasn't just some gasket goop that got into the holes? Or does it specify somewhere in the subaru repair manual that 3 of them actually need sealant?
