Either the two screws holding the pump to the case are loose, or the main (thick) oil pipe is split. Can't think of anything else it could be.

Not sure what the RSX pump looks like but I presume it's an Autolube one. Could be the seal on the end of the drive shaft or maybe the bleed screw has been left loose.

thanks guys, i just found the bleed screw snaped off and the hole filled with some sort of glue, and oil was coming out of there. i was able to fit a very short screw that sat flush and tightend up, hopefully it will hold and stop the leak......wont be able to bleed system tho but as its been doing this all along i dont think it would need it.....what do yous think? thanks in advance

Why has it stopped you being able to bleed the pump?

If you can use a fibre washer, you won't have to tighten it up as much to get a good seal.

hi, there is whats left of the original bleed screw still in the hole, there was enough thread to screw another short screw in.....ive just had it ticking over for a while and noticed an oily residue running down the down pipe from the cylinder head end.....its not blowing tho. i had a scooter that did the same but that was over jetted.....120 main jet in at the mo

The oil from the downpipe is no big deal, it might mess up the downpipe but it'snot unusual. Might juust be a case of using a new gasket. If you do, give the mating surfaces a very good clean before sticking it back together.

It might be possible to remove the bust bit of thread in he oil pump, can you stick up a pic?

finally got the the rest of the thread out with a needle and a stanley knife blade, it was actually quite loose luckly.....i do need to know if the pump is set correctly tho... see pic, its as it is with the throttle closed and engine off....... Thumbs Up

thanks
