I replaced spark plugs and coil packs. Barely drove it then it lost almost all power. Replaced crankshaft position sensor, ran better but still no power. Now all the plugs have fouled, it's burning rich on cylinder 1+2+8, and valve cover gaskets are leaking. Still cranks and I can drive it but it running rough and doesn't have enough power to really"drive" it. Has barely over 113,000 miles. 4.7 l v8. Never had a problem before this. What is wrong with it?

Good morning,

I would start with a compression test on all the cylinders to be sure nothing is wrong inside the motor. These engines have a history for burning valves.

Are there any codes set in the system? If there are, do you have them? It will help narrow the area of failure. You can have them read for free at a parts store.
