Hello
i picked up my super wd9 and brought it home yesterday. The motor is stuck, so my plan was to pull the spark plugs and put some PB-Blaster in the cylinders. Plugs number 1,2,and 4 came out fine and looked good, but #3(which is right behind the intake manifold) did not. I could not get the socket on there, so i looked a little closer at the plug. It turns out to be that some moron put a different smaller plug into that one. The part that the socket grips is flush with the head. So i ground down a socket to where i hoped it might work and tried it. End result, the plug is rounded off in a perfect circle in the head. Does anybody have any ideas on how to get this out? Any help is appreciated! Thanks
 
The only thing that comes easily to mind is to: - break the ceramic top right off and weld a nut on to the part left in the plug hole. The nut should be small enough to get a socket onto but of course as large as possible to take the necessary force. You might have to do it several times as the nut may well break off. The other advantage is the amount of heat generated by the welding will help shift the plug. MTF
 
Most times when those diesels are stuck the head will probably need removed. Unless you remove the valve cover and get all valves open and including a starting valve opening check, the penetrate won't make it. May want to remove injectors and if you get it unstuck without removing head worry about the plug then.
 
Good tactic with the head off, if he is trying to save the head removal (probably futile, but worth a try)I would weld a smaller cheap (Pawn Shop) socket that allows you to put weld on the rounded part. Breaking the insulator off, and out, can put ceramic chunks into the compression relief chamber. Then the head -will- come off. Jim
