So its a 2005 v6 auto tranny with less than 125k miles.
Never had an issue, we do not live in an area with really steep terrain but are on a trip in the south with inclines of greater than 7 to 15 percent.
When we go up these steep inclines it starts smoking and smelling like engine oil burning. When I stop it appears to be coming from under the car in the back. NOTE, the exhaust does have leak so thinking it's coming out of that.
I wondering if the issue is the valve stem seals on the most rear cylinders are cracked/leaking and when going steep uphill the oil is all going to the back of the top of the heads and leaking down in??
Looking for advice on what could be causing this.
Thank you
Phil
