Today I tried to exchange the spark plug wires. However, I almost pull out my hairs for these two donuts removal. Can someone help me that? Thanks a lot.
1. P5: How can I remove the covering plate under oil filter cap? If I don't remove the plate, is it still possible to pull out the donuts? I find the donuts are very difficult to pull it out without removing the plate.
2. P6: I tried to remove the rotor too. However, I ruined the hex screw hole because the screws are stick on the plate. Right now the hex wrench can't move them at all. Any way I can do it now?
Any suggestions are much appreciated!
Just slide it towards you, May take a small yank, use both hands, Thumbs on top.
The struggle is real.
Just pull the plate towards you. Mark the plugs for re install later cause you might mix them up.
Use locking pliers on stripped bolts.
Go slow.

Used a small short hex wrench? A long shank or t-handle hex wrench will work much better than the shorter ones. Breaking loose a ‘stuck’ bolt becomes much easier due to better leverage/torque provided by the longer handle. As stated already by dragon850, your best bet now is to use a medium size toothed locking pliers for the stripped hex bolts.

I had luck using a 1/8" hex socket attachment for my ratchet wrench.
I used a small hammer to tap the socket attachment into the stripped holes.
There are numerous threads on here that discuss the procedure involved in removing and replacing the donut (or cam position) sensors. Pay close attention to the instructions for removing and replacing the wire ends and boots.
I did it. Thanks a lot for all your help. Happy Lunar New Year!
