Please Help

Do u have a pic of the seal i'm sure if they gave me the right 1 I'm stumped don't know what else to do

My camshaft is leaking cause it was missing the plug I just received the plug today.Do I have to take the valve cover and the rocker arm assembly off to install

The plug and do I need to put sealant on it

Ok im Back so I fixed the oil leak now i'm getting gas in my oil i changed the fuel pump and put all new gaskets on the carb was rebuilt a yr ago any suggestions?

there is really only one point where gas can come into the oil, and that would be at the fuel pump. The only other possibility would be that you have worn piston rings and fuel is getting into the crankcase that way, but you would have a loss of power and your truck would feel even more sluggish than usual.

I have to start it from the voltage regulator cause the ignition is bad in order to get it to start i have to hold the choke and when i let it go it stalls
