So I went for some light spirited driving today. MR with Stock motor, ets t3 twin scroll kit with gtx2582r, and stage 3 ssp clutch kit. While at 3/4 trottle I had a really brief boost spike (normally 17-20psi, spiked to 23psi) and the transmission acted a little strange so I let off and babied it to the nearest large parking lot. Popped the hood and checked all my vacuum lines, everything is buttoned up and undamaged. Restart the car and it was fine so I took it home.

Got home and not even 2 mins in the driveway I peek under the car to find a very thin but palm sized oil leak on the ground. Freaked out cause I am a novice at wrenching and popped the hood, top side completely clear. It appears to be around the oil pan seal just above the drain plug.

Is that a common leak? Any idea how much it will cost? Also is that a possible result of the breif overboost?

Sorry for the long question
