I am doing a head gasket job on my 1994 mitsu mighty max 2wd, its all stock and in pretty good shape. I am having problems with the silent shaft so to speak. I am on the part where I take the plug out of the side of the block and stick something in to lock up the shaft. I am unable to get anything into this hole to lock it up. I have talked to several people and had a couple look at it. I have not had any luck. It looks like something has been broke off in the hole where the screwdriver goes... I have tried turning the oil cog a full rotation, still can not get anything in the whole further than about 1/4 inch.... anybody with any help please let me know....
