Got three questions I'm sure most people can answer.

Ok one I took off the upper intake the other day to adjust roller rockers again and I saw that after having new gaskets on for like one day they inside near the intake ports (lower to upper) were wet with fuel. What is causing this?
Also I only really noticed towards the rear of the engine and not in the front.

Next question, as summer is coming up and I need to do an oil change in the next few days, which grade oil should i go with? Usually I go with 10w-30, but wondering if I need something thicker for the hot weather?

Thirdly, I have pretty much fixed my oil leak, but I have noticed a very small drop and I think this is coming from my oil pan nut (where you drain it). What do you guys use on it after changing oil? A bit of thread sealer or RTV?

Thanks.
