Probably not the head gasket. If oil (or anything, really) were coming out of your head gasket, you'd also be smoking like crazy and running rough very shortly.

Step 1 would be to clean your motor and identify the origin of the leak. Whatever gasket the leak is coming from, replace that.

im going to clean the motor soon once i get my spark plugs replaced ill have more room to do some cleaning , now im thinking its coming from the valve cover gasket because its from the top of the motor and i have oil in the spark plugs

also a quick suspension question since your a huge help with a lot of things i have , when it comes to the traction bar whats the best method to remove the bolt that is on the chassis i got to take every other bolt off but that one i got to take the nut off but the bolt it self did not want to move at all i havent tried wd40 yet but just wanted some input on that before i try anything else

Regarding the stuck bolt, in general if a bolt is resistant to being removed, do not use excessive force to persuade it as you’ll likely end up breaking the bolt.

Use heat, preferably from a small propane torch, them let it cool, spray a little lubricant, heat again then try removing the nut.

Good luck.

If it's the passenger/lower area, guessing the power-steering pump/hoses.

With the fans running, oil will go where it wants. We had a Camry with a leak so bad (oil pump o-ring), the rear bumper had an oil-film on it. Liquid will go where gravity and wind drives it...

Yet I'd go back to, clean the engine, and see where it starts.

hmm that would make sense but how am i getting oil in my spark plugs ? i pulled the coil off and it was drenched in oil which is why my crank sensor went bad since i was having to much electricity running into the spark plugs , i mean thats what my mechanic said . once i change my spark plugs and get the oil out of there my car should start so ima start there and see whats going on once i clean the motor . but i will be checking where is my power steering pump leaking from also . Again i appreciate all the help and input your giving me brother .

There are some seals in the valve cover the goes around the spark plugs, these get hardened over time due to heat and cause oil to leak into you spark plug wells.
Part number for the Toyota seals are: 11193-70010, you will need 8 of these.
Be sure to clean as much of the oil out of the wells before you remove the plugs.
