Hey everyone I have two videos of my truck acting up that I have been trying to figure out the issue. it stopped when I cleaned out #1 and 2 Cyl which was filled with oil, now there's no oil and it started acting up again.. Listen in the video

 

What codes are set? I see the lights flashing on your dash. You would need to give us some codes to help you out. The 97-8 are different systems than the 99 and newer and all 5.4's. I hear an exhaust leak, but can't distinguish what the noise in the first video. Oil in cylinders is usually a valve guide or head gasket problem, but right now it is like peeing in the wind. It doesn't work. It could be internal engine or as simple as couple wires messing up. Hard to tell.

 

When I had codes ran last week it was telling me i had a Oxygen Heat sensor bad. Downstream on the pass side from the Cat.. The mis fire causes my exhaust leak to be Really Loud and hissing..

 

Pulled the plug wires, no oil blew out the CYLs and replaced and still acting up with a misfire and stuttering

 

Mine was doing something like that too, and 2 of the spark plug was ''loose''...
Does yours have been replaced recently ?

 

Yeah... They were I will have to check...

 

I also have another noise like that and its from the exhaust manifold, dont know exactly if it is the manifold itself or just the gasket but i noticed 1 missing bolt, you should chek that out too !

 

I have a bad exhaust manifold gasket as well, I'm getting it redone soon.. Or may attempt to do it myself..

 

Did you take them back out and re thread them in OR did you just crank them down to the ft torque required?

 

And by chance prior to it happening did you plug wires pop out of the Cyl?
