Plug boots coming off plugs

Yeah, kind of. The valve cover gasket needs replaced. The seals around the plugs go first because of heat. If the oil mark was near the top of the plug boot, replace the valve cover gaskets/seal. If it was near the bottom, slap in the plugs and wires.

Yes. The valve covers have seals that seal around the spark plug tubes where the plug wires go down through the valve cover. A valve cover set should come with the spark plug tube seals. This is a common problem with Honda. I also recommend replacing the plug wires because the rubber boot can get saturated with oil and cause a misfire. Sometimes it may look like the boot is clean when you wipe it off, but the oil is still in the pores and can cause the boot to allow the spark to arc over to the spark plug tube. Most of the time the ceramic on the plugs gets messed up also. This can also cause a misfire. If the plugs have any brown or black discoloration that does not easily wipe off with a rag, then I also recommend replacing the plugs. The discoloration is caused by carbon. Carbon is highly electrically conductive. This will allow the spark to travel down the side of the ceramic to the metal base of the spark plug.

yes, the valve cover gasket is the only thing that can cause this, and yes, you have to remove the cover and put a new gasket in to fix. Please let me know if you have more questions.

the oil was the cause of the misfire, the oil swells the rubber on the plug boots and interferes with the electrical connection from the wire to the plug. when you replace the gasket, remover the plug wires, marking which one went where, and use a spray electrical cleaner to remove the oil. make sure the rubber on the new wires isn't already swelled. before removing the plugs or valve cover, spray brake cleaner down in the holes and use compressed air or shop rags to get the hole shiny clean before removing plugs. remove plugs and clean them too. then reinstall plugs and remove valve cover. when replacing any gasket, use a razor blade on to clean the surfaces well. you can even spray a shop rag with brake clean and wipe it to make sure its clean. clean is important. reinstall cover with new gasket in place and torque bolts... be careful not to overdo it, they are small bolts and overtightening can flatten out gasket and cause more leaks. then just reinstall plug wires and off you go

you have a bad valve cover gasket/ spark plug o-ring i assume the plug is set in the head with valve cover above it since there is oil in the cover gaskets and o rings are used to seal in oil remove and replace gaskets be sure to find the right torque spec for the cover bolts also remember to start with the center bolts and work your way evenly to the outside

When you put the new valve cover gasket in, you did place the o-rings in their proper position under the valve cover, right? Maybe I'm misreading your question, but it sounds as though you put them down in the plugs holes under the plugs. If I'm wrong, I apologize.
Hope this helps.

The spark plug change is very straight forward. Basically, you remove the plastic valve cover trim panel, unplug the harness plugs from each of the ignition coils, remove the two nuts securing each coil, pull the coil up. The rubber spark plug connector boot should come up with the coil. You can now remove the spark plugs.

The spark plugs are not gappable. Install them as they come out of the box.

Replace the rubber connector boots at the same time, these wear out and can cause miss-fire problems.

Note that if you find oil in the spark plug wells, the valve cover gaskets must be replaced. Not only does this make a mess, but it deteriorates the boots and also causes miss-fires.

after purchasing replacement spark plugs and wires and making sure to have them correctly gapped use a 5/8 spark plug socket remove one at a time and replace in that order to make sure you dont mess up firing order gently remove boot on the first plug then unscrew plug place new plug in secure wire by snapping boot onto plug if theres oil in your cylinder youll need to replace tube seals common problem with hondas seal kit comes with valve cover gasket its fairly simple.
replace all of them the same way one at a time.

you will have to put another valve cover gasket on between each cylinder there is a round gasket between valve cover and cylinder head if you buy the valve cover gasket kit they will be in the kit .please rate this answer thanks.

a new valve cover gasket and o-rings around the wells should have cured this...did you clean the old o-rings off the valve cover completely before installing new ones? this is a common problem with these models.....i would re-check my gaskets and mateing surfaces. valve cover gaskets and spark plug well o-rings are relatively low cost. the spark plug is tight, correct? write back with an update!
