i did a tune up on my new supra last weekend and found i had liquid oil covering the threads on my fifth spark plug. oil did not look burnt or crusty and i payed more attention when i pulled out the 6th plug and found that oil was coming from the top and and leaking on to them. i was just wondering ware it could be coming from also i noticed an oil leak towards the back of the motor. doesn't look to be ware my head gasket is located what might cause this to happen. thank you for any input i can get. I'm a novice with these cars so anything will help.
