I was able to install a helicoil, i wasn't able to take off the head. i thought everything was ok after i installed the insert with the new spark plug. It seemed like everything fitted tight and snug without me takin the head off. so the i proceeded to let the sealant cure from a job that seemed well done.
but 2 hrs later when i went to start the car it , was shaking voilently. clould it be because the car need to rebulid compression.
why why was it shakin and stalling out so much?
I did drive it for like two minutes inially when the no#1 spark plug flew out the cylinder head could that have something to do with it.?
I also smell gas. Is that a bad sign?.
