Replaced the valve cover gaskets, spark plugs and boots this past weekend. Gaskets where in bad shape. Literally petrified in the valve cover. I've never seen gaskets that bad, glad they are done. Biggest hurdle was the stupid injector harness and having no room to work with on the driver side with the dang hoses. After several cursing fits things went smoother. There was A LOT of oil in the spark plugs. Especially in cylinder 3/4, 8 was pretty bad not the level of 3/4. While it drives a little better there is still a misfire in cylinder 5. The spark plug there wasn't bad, had normal fouling. I will try to swap the coil to another cylinder and see if it follows. I can definitely here this misfire in the exhaust on the driver side when I stand behind it. Sounds like a super loppy cam. So will try to swap 1 and 5.

Another thing that is kind of weird is the acceleration. From a stop and in 2nd it pulls pretty hard, once it's past 2nd there is no power, like honda 4 banger no power. I can be at 3.5-4k RPM's mash the gas and get nothing.

I'm hoping it's just a faulty coil and can get this beast ready for summer. Only got to put 400 miles on this year so far.
