Hi I just did a head gasket on a 2014 fusion SE,1.5 ecoboost.got everything back together and it's a crank no start.ive triple checked timing.i finatdid a compression test and #1-135psi,#2-4 I only get 75psi, so I shot a squirt of oil in each and I had 135 on all 4 cylinders...this leads me to believe I have worn piston rings? Anyone else experience this? Or any input will be greatly appreciated.
