Fellows: Son is changing out the plugs on his '10 4.0l v6 engine. Had 4 of the plugs out and new ones installed. He got the 5th one out, cleaned up the head threads but for the life of him he cant get the new one installed. The new one will simply not start into the head threads. Neither will the old one he removed (OEM Autolite 5143) screw in. He tried a plug thread chaser but it won't "gently" start. He's ground down the threads of one of the old plugs and get get it threaded into the plug hole but it stops and he's real leery of cranking down on it.
He's currently got a piece of hose over a new plug insulator hoping to get his alignment just right but is not having any luck.
Any ideas?
