Car (2006 Pontiac Pursuit, 2.2l auto with 140 000 kms)has developped a small oil leak that seems to be coming from rear main seal or oil galley plugs (as per TSB 06-06-01-013).
Been running 5w30 full synthetic oil since new and now thinking of going to high mileage oil hoping to get rid of this leak ( a few drops on the garage floor overnight ). Maybe lost 1/4 of a liter in the past two months.
Haven't heard or read anything really good about additives to stop leak
Trying to avoid engine or tranny removal...any suggestions!
