Unfortunately I feel like I have exhausted all diagnoses besides a bad motor on this 01 Accord.
It started as misfire on cylinder 3. I found the tube seal was leaking and the plug was wet so I cleaned it and replaced
the valve cover gasket, tube seals, bolt seals, and plugs.
I tested spark and checked wires for leaks, swapped the distributor and wires, have new plugs...
the compression on cylinder three was low and leaking until I adjusted the valve lash and it is now within spec...
the car had a clogged egr when I bought it a year or two ago so I took off the top of the intake and the
egr and cleaned everything including the passage so to make sure that isn’t the issue...

so spark good compression good fuel is ok I guess Bc it’s running and the first two cylinders no problem
but now also cylinder 4 is misfiring. I’m not sure what else to test and am thinking the motor is no good?

any ideas?
