Having problems with your 2003 Cadillac CTS ?
Oil leaks from the passenger side on a 2003 cadillac cts 3.2 v6 already put new valve cover gaskets its still leaking oil and leaks a lot what can it be
I was told by the dealer that the 2003 CTS has plastic valve covers and they warp. To cure the leak you need to replace the valve cover.
Check front crankshaft seal from under car, see if you see oil coming out of back of pulley.
