Spark Plug Blew, How to Repair Hole

I have an engine with a blown spark plug. What are my options? Please advice.



Hey there Jose,

I am assuming the threads of the hole are messed up now and you can not install a new spark plug. If so, you can have your mechanic try to install a heli coil insert into the hole or if that does not work….you will have to remove the cylinder head and send it to a machine shop. shows a picture of the helicoil insert
