blowby tube
 
one the injection pump side of the engine on the side cover towards the rear of the engine, there is a little tube pointing at about 4:30 towards the firewall. does something connect to this tube or where does it go. i believe i have oil coming out of it im pretty sure thats where my leak is coming from. anyone know what that could mean? thanks

Its your crankcase breather its supposed to have a little tube on it that goes down below the engine they all slobber a little oil out of them (but not enough to see a drip on the ground) if you have alot oil coming out of it that means your getting excessive crankcase pressure most likely caused by worn out piston rings
