About a week ago, I hit the gas to clear an 18wheeler merging onto highway while already doing 75mph. Immediately after I felt the truck was off and the engine light popped on flashing. Knew something was up and figured misfire. Got to a spot to exit and check it out. Cylinder 8 misfired. Ran rough from idle to drive where I could physically see the hood shaking. Later on, the tick came into play. Not the hemi tick that I’ve had and been very familiar with as I’ve learned my truck and all it’s sounds. This is much louder and coming from what seems to be the passenger side near cylinder 8. Easy to tell through the wheel wells with plastics off. Also very easy to hear from under the truck near front of trans. Can’t pin point where it’s coming from but it’s louder than it’s ever been. It seems to go with rpm but sometimes it fades away for a min or two then comes back. Definitely ticks or clacks faster with rpm though. Loudest at cold start 40F-50F and low rpm’s but definitely still there at higher speeds jusy only able to hear with window down and driving past say a wall or something so it bounces off and is easily heard. One more thing I should definitely mention, I took out the spark plugs for cyl 8 and the plug closest to the firewalls gap had completely closed. Touching. Very confused on that as I know it wasn’t that way when I installed them. Yes they are the right NGKs for the truck.
High mileage truck that was used for daily hauling welding trailer and metal.
Any ideas would be appreciated. Also thinking about switching over to the redline 5w30.
First time post but I’ve been in these forums a while now always reading to learn more about the problems I’ve experienced. Thanks guys.
