Cant get this screw out to change spark plugs. Tried drill bit screw extractor and it’s not working. Any suggestions?

Lots of techniques for this.

But first, get some Liquid Wrench and soak that bolt for a few days.
Really soak it good.

If drilling the bolt and inserting an Easy Out bit did not work, which to me is surprising, I would try a Dremel tool to slot the bolt head to use a flat blade screw driver in the slot to try to remove the bolt.

Take care to not damage the valve cover by placing layering of blue painters tape around the bolt.

That is at least one technique you could try first and perhaps the least destructive, so you can move to other techniques if that slot fails.

Good luck wished to you.

OP,

I've used this method a lot over the years on various things. It works well.

Remove the rest of the hardware holding the cover on, lift the cover at the free end and turn it to break the screw loose. Just be careful as to not scratch anything as you rotate the cover.

once it's removed like the other members have said. PLEASE for God's sakes brother clean that cover before installing it and the engine bay while at it LOL I'm having an anxiety attack here my man. lol 🤣

keep us posted how this turns out for you. The plugs should be easy to take out so let us know if you have any issues w/ that.

A quick note: Make sure you are using the proper bit for removal of the original screw / bolt. Wether it is a Torx / Triple Square / Hex Etc. Guys will use a hex on a Triple square, even though it technically works, its not correct. Good Luck. And as said above, PAINTERS TAPE IS YOUR FRIEND.

To add to the really good advice above: use the proper high-quality bit in a good quality hand impact driver (if it fits down there) and give it a couple of light taps using a light hammer or plastic mallet

Thanks this helped a lot. I tried everything. Sliding the metal cover broke the screw loose. Made the screw realllly easy to take out, I was able 2 cut a slit again for a flat head with a dremal and got the cover off

Im glad it worked for you.

Watch the small coolant lines on the reservoir. When I changed my plugs these had dry rotted and broke while moving the reservoir.
