Question about Toyota Cars & Trucks
The simple answer is, there is not much point in doing so. The HP you could add will be hardly noticable. But if you wish so than: sports air filter, one of those coney ones, they do increase airflow so add a few HP. To make full use of that extra flow you'd need to unchoke the other end- sports exhaust. If you are really commited then you can take the engine apart and give it a good clean. Essential part here is porting and polishing intake manifold- again to increase the flow.
But- is it really worth doing that to old toyota? Remember- she's grandma now ;-) I'd be enjoying the ride with the car of the age where most of it's competitors are long gone to the heaven of scrapyard and memories. You've got a masterpiece of a car. Its still on the road because Japanese engineers have created it to last. Start making modifications and you'll kill their efforts. Cheers

If Biggy1 has described it right, I think when you remove the WIRE to the spark plug ( not the plug itself ) and oil jumps out, there is a cylindrical seal that needs replacing and one does not need to even remove the cylinder head.
I have the same problem with my corolla. On the other hand if Biggy meant when removing the SPARK PLUG oil was on the contacts....

You need an aftermarket serviice manual from Haynes or Chilton.
They will have that kind of info.
I know of no car (I don't know them all) where that is needed and depending on the cover material (sheet steel or cast), could lead to warping and new leaks. I always use a thin film of silicone whether it is specified or not and there are torque specs for ALL valve covers I have ever seen.

Probably a resetting circuit breaker in the system. Some are reset when they cool off, others when keyed off. Must be something drawing too much current, or circuit breaker getting weak. Usual causes of drawing too much current in your case would be power window motors. With that said, there are some things you can try to lessen the load on the circuit such as spraying silicone down sides where felt is for easier window movement. Those areas get dried out and tend to grip glass as it's going up & down causing extra load on motor. I've also had to resort to removing door panels & spraying grease on tracks & guides inside door, to help. try silicone down sides first and see if it helps. Also make note if one window seems to cause it more than another, that gives you a good one to start on.
