Outer Limits 4x4 Board

Hey i have a 80 series with a 1HZ and the diesel injection pump is leaking, it is the O ring behind the RH timer cover, just wanna know if anyone has had this problem & is there is a easy way of replacing the O-Ring it... cheer

i could attach a pic of what i mean if i knew how :-)

I fixed mine, there are two o rings in there, one behind the body and one inside the thread of the adjuster. To do the body, just undo the 2 allans and it comes off in one piece. too easy.
If it is the one inside the adjuster, you need to meaure the distance it i in from the back face and reset afterwards.
