This would not cause your car to leak more oil than before.

A: Where is it leaking from?

B: Did you change the metal ring on the drain plug and torque it correctly?

C: Did you spill any oil on the subframe or underpan when you swapped the filter?

 

1. I haven't pinned pointed the leak. I want to say it is the valve cover. I am gonna change the oil pan gasket too.

2. I ordered a new drain plug from ecs tuning and it cam with that ring on it. Never before used Drain plug. I didn't torque it down but that can't be it because the puddle of oil is in the middle of the car. It leaks onto the front sway.

3. All oiled spilled during the oil change was cleaned. I always clean up the underbelly of the engine after every oil change.

 

That's quite a bit of work. I'd clean up the engine bay and look for where the leak is coming from before ordering gaskets.

 

Valve cover gaskets are very common on the 2.8.

 

the reason I think it is the valve cover gasket is because I have a minute amount of oil in the holes where the spark plugs go. But not enough to foul the sparks plugs

 

Any amount of oil in the plug wells can cause ignition issues. You can get a leak detection dye kit from a parts store. Clean up the engine, put the dye in the oil, and look for leaks in a few hundred miles.
