the hole was a dead end hole you drilled all the way thru and into the water jacket. depending on the model of head you just made sure you get to buy another and replace the one you drilled.
Next time go to a mechanic that knows what they are doing.
No, if there is coolant in your valve cover it'll be mixed with oil. You blew your head gasket, possibly warped or cracked your head. It may look like coolant is leaking from your valve cover but it's your intake gasket leaking.
The head gasket seals the head to the engine block. Coolant and oil flow through the head. The gasket prevents then from mixing together. The valve cover gasket only prevents oil from splashing onto the engine and exposing the valve train and moving parts to the outside of the engine. No coolant makes contact with the valve cover gasket.
They are located through the center of the valve cover.They are located through the center of the valve cover.
They are under the coils through the top of the valve cover.They are under the coils through the top of the valve cover.
its right next to the valve cover on the driver side behind the coolant sensor
No, only a blown head gasket or cracked head will cause coolant to mix with the oil. A leaking valve cover gasket will only cause oil to leak onto the engine block externally.

Sensor to the ecu is on the drivers side close to the front on the engine block right below the valve cover. The sender/switch to the gauge is on the diver side. On the valve cover close to the fire wall... Same location that the bolts holding on the valve cover r in.
The exact location of the PCV valve on a 3.8L engine depends on the year. On models 1995 through 1998 and 1999 and 2003, it is on the front valve cover. However, on 1996 through 1998 models it is on the rear valve cover.
There is not a heater valve in a WV Passat. Instead, coolant moves through the heater core at all times.
driver side valve cover between coolant jug and turbo.
NO. The valve cover gasket seals the valve cover from leaks. The valve cover covers the valve train and it's components and it bolted to the top of the head. These components sit atop the head. The head is bolted directly to the engine block with another gasket. Water and oil flow through the head.
