GS300: P0300 P0301 P0303 P0305 + Spark plugs drenched in Oil
So some basic info.. Girlfriend was driving the car in heavy socal rains this past week when CEL came on and car started to bog. I limped the car home and plugged in my OBD scanner and found out it was throwing P0300 P0301 P0303 P0305 codes.
As for the car, it's a 2000 GS300. The spark plugs were changed about 10k miles ago. Oil is changed every 5k to 7.5k with mobil 1 synthetic oil 5w30. Car currently has almost 180k miles and is my daily driver with no engine mods.
I decided to check out the spark plugs and noticed they were drenched in oil. The valley had a little bit of oil also, but I assumed it was from adding oil and spilling a little bit. After cleaning it off, I tried starting the car again and it started blowing white smoke from the engine area, not specific to a certain cylinder.
I currently also have a cam shaft seal leak or VVTi seal leak. I bought the gasket for it, and figured now is as good a time as ever to change it. I also purchased a valve cover gasket that has yet to arrive. Anyone ever have this sort of issue and if so, what was done to fix it? Any help is appreciated. Thanks guys.

Your valve covers are leaking. Change them. That will keep the valley from filling up with oil. It was blowing smoke because all that oil in the valley poured into the engine when you pulled the plugs. Oil in the valley combined with water could very well be the reason you threw those codes.
When you change your timing belt(you have right?), you should change the cam seals and the valve cover gaskets among a bunch of other things.
Where in so cal are you located?
