I understand your problem... yes probably someone here could give you a hand (hopefully), I d'love to help but I am a bit far
As for driving, DO NOT WORRY, as long as it has enough oil, you're fine, it might seem a bit impressive, disgusting and become very dirty under the hood but this shouldn't harm anything AS LONG AS YOU HAVE ENOUGH OIL ;-)
I can explain you the way to do the job (so that you already know) :
- remove spark plug wires from the spark plug wholes (quite easy !)
- remove the big four bolts on top of each spark plug wholes (super easy, you just need a big socket)
- remove the valve cover (which is now unbolted)
- replace the gasket (3.5 seconds)
- refitting is the reverse sequence to removal
Just let us know if you need any more info !
