which gaskets or o-rings could be the cause. i just rebuilt this thing and its already leaking (sigh). but i used new gaskets and o-rings so i'm stumped. i haven't taken off the bottom cover yet, prolly tomorrow. any guess's before i tear the timing side apart???

It 3sgte or 5sfe?

I'm gonna guess 3sgte
Possibilites in that area:
Cam O-rings, Oil pump gasket, oil pump itself, Valve cover gasket.
Did you use a sealant around the cam brackets behind the Cam gears?

I pulled off the top cover last night and it didnt look like it was leaking from anywhere up top. i shoved a little mirror and light in there and it looked dry for the most part. im gonna tear apart the rest today after work

i took off the bottom cover tonight and two of the interior bolts of the water pump ( the peice with the gear) came out completely cause i must have stripped the threads when putting them in. i think i found my leak.

So you are leaking coolant form the water pump? I thought you said it was an oil leak?

OH, OK, glad you found and fixed the culprit.
