Hmmmm well this is interesting lol. I dont seem to have an oil can. My setup is different, basically the line from the rocker cover goes to the throttle bit is where that line is.
edit: Ok well mine goes straight to it like a straight line lol. from ur picturs i thought ur line went to the oil can then back to the throttle body. I dont think its blocked but i'll go try unblock it anyway. If u can go on msn please do so ive added u lol.
