when they leak, oil pressure switches can leak a lot due ti being under pressure. It can pool and shift around under acceleration/maneuvering and drip almost anywhere.

The injectors are most likely now not passing any fuel and need to be removed and cleaned. Same for the fuel filter. Engine will never start on 20 year old fuel.

No - just relax and get it properly diagnosed. It's probably one of the oil switches leaking, valve cover, or CV boot, or something else really easy. The mechanic is doing you a disservice by sending you on an anxiety ridden internet search of head gasket woes. Maybe he had a bad day when you stopped by, I'd just carry on and not worry about it. You could look underneath or pop the hood and attach any pictures of fluid you see here and we can help. If it's a CV boot - reboot the axle. The original axles will last the life of the car and are literally stupid to replace or throw away. Many shops will want to replace the axle because it's quicker and simpler for them - the cost is roughly the same. But aftermarket axles are terrible and almost never last the life of the vehicle.
