2006 XC90 big leak after Seafoam

[Cameron115]

Hey guys new to this forum still trying to figure out how it all works, but i seafoamed my xc90 2.5t today before an oil change i ran about half a bottle in the crankcase and a little less than half in the vacum lines. Let is sit then ran it about 10 minutes to change the oil. I went to change the oil and the motor was leaking bad and it was not leaking before. I recently did the pvc trap i checked all the hoses and re assembled everything, the leak has so far not shown back up exept for in the back near the timing belt.. but very slow, i can smell burning oil. Any help or input is greatly appreciated!
