Oil in the spark plug wells

Hello Sir!

   First off, LOVE your channel. You are amazing and very entertaining to watch. I have a question about an issue I am having on a friends car. She told me that it started bogging out and now it cranks but won’t start. This is a 1999 Mazda Miata L4 1.8L. Upon inspection I noticed after removing the spark plugs the electrodes were completely worn and the spark plugs were covered in oil. I replaced the valve cover gasket but it was my first time doing that and I’m not sure if I tightened the bolts properly as I didn’t want to overtighten them. But I also replaced the spark plugs and the wire set but it’s still cranking but won’t catch. I am wondering if the cylinders are full of oil I imagine this could be the issue but how can I check that and what would be the best method to cleaning the oil out of the cylinders? The valve cover gasket also has the spark plug seals attached and they must have leaked and a lot of oil got underneath the spark plug in the cylinders.

Use a torque wrench and make sure you tighten the head gasket up to par according to specs. On would also do compression test to make sure that the piston rings are fine.
