I reset the C.E.L. Drove 190 miles and the C.E.L. came on. Check it with a code reader and P0420 came up. I understand that is the catalytic convertor code. #1 I know the valves seats are leaking. It smokes a little at start up or if I sit idling for a length of time when I take off it smokes. #2 I have 2 broken exhaust manifold bolts on the drivers side. Would this cause the P0420 code ? If the coolant is leaking where is it going?
