I have my engine out for a bear tub restoration. I am reassembling everything and almost ready to put the engine back in.
As I was cleaning things up replacing the tube seals and getting ready to adjust the valves I found these threaded sleeves in my spark plug holes.   Looks like a PO was a DA? Did they strip all of the spark plug threads and use threaded inserts? I probably wouldn't have even noticed but they are loose and partially back out when I took out the plugs. They are at different depths now but do they bottom out when the plug is tight? I can't tell because the base of the plug covers the sleeve when the plugs are in place. I really don't want to take the heads off. I had no issues prior. If it ain't broke don't fix it? Or am I risking a bigger problem? |

Thanks for all the input guys.
I guess I won't be putting the motor back in this weekend. (IMG:style_emoticons/default/mad.gif) I will pull the heads and post some pictures for further advise. I will probably be calling Jeff's machinist soon. Thanks Jeff. And the resto was going so well too.   |
