Hi,
A few months ago while my 2011 Cruze Eco MT was still under warranty I asked to have the cylinders pressure tested because of oil on the spark plugs. The GM service tech performed the pressure test, it failed, he said he would replace the valve cover gasket. The following day while I was picking up the vehicle he told me instead of replacing the gasket, he tightened down the valve cover because it was loose. He did not install a new gasket.
Today I decided to check the gaps on my spark plugs because I noticed a rougher idle than usual. Here is what I found.
First image firing order - 1,3,2,4
Second image firing order - 4,2,3,1
Rest of the images are firing order - 1,3,2,4
