thoughts on this problem im having problems with oil on the spark plugs ever since i pulled my intake off. i have brand new rings and dont think this could be the problem. is it possable to leak from the intake manifold?
How old are your valvestem seals? Also, did you reuse your gaskets for the intake and what brand?
I'd double check the torque on the intake manifold bolts. Could be leaking past the gasket into the the intake runners. If that doesn't help, you may find yourself having to pull the manifold off again to check it out. If you see oil on the valve faces or any prominent oil trails going into the runners than the gaskets need to be replaced. Granted, there could be another underlying problem (valve seals as suggested ^^^), but rule of thumb is that if a problem starts after a repair, check the last thing you touched and trace it back from there.
Oh, and I'd hope you wouldn't have reused the original gaskets.

i didnt reuse the gasket but when i built the motor i did notice the gaskets that i bought were cheap, they were like made of plastic or something. all the plugs have oil so im sure its coming from the manifold, how does it touch the plugs tho???
The lifter galley has ton's of oil splashing around and if your intake gaskets are crappy or leaking then oil will get past them into the runners and then sucked in with the air to the cylinder.
The oil galley sits right under the manifold. The gaskets (and rtv at each end between the heads) are used to contain the oil as well as prevent vacuum leaks from the runners between the manifold and heads. The fact that it is leaking on both sides and affecting all cylinders hints that the manifold is either loose or you installed both gaskets incorrectly.
I doubt all the valve seals/piston rings are likely to all fail simultaneously. Everything points towards the mani gaskets so tighten it up, let it run for a little bit to allow the residual oil to clear out. If not, your just looking at replacing both gaskets as aforementioned. If you have to tear into it again, be sure all the gasket surfaces are clean.

so this problem started sunday night when i raced a 04 gt with 135 shot, went from a 20 roll 1st gear we both side by side 2nd i get a half car on him then my car cuts back so bad it felt like a spark plug wire came off i check all the wires everything is fine i pulled 5 plugs off all fine so far but its braking up bad and i have no power all of a sudden. i thought it could be from oil in the plugs but so far it doesnt seem like its the plugs and i have a new opti. ANYONE HAVE ANY IDEAS WHAT ELSE I SHOULD CHECK?????????

the motor is shaking and **** im gonna replace all the plugs again i had 2 bolts off the intake loose. all 5 plugs were ok but 1 had a little oil but its still cutting back like if its miss firing or skipping braking up bad down low.
Did you check the Coil and ICM. Cutting out usually leads to an ignition problem. Also, triple check all ur wires as you could have a burn sp wire that is arcing or grounding on a header.

somthing else to think about (if you still have one) check your pcv system and see if the lines are coated with oil
