Awhile back at 120k miles I changed my spark plugs on my 03 Vibe and I managed to strip/break practically every coil pack bolt as I misread a torque spec. In my panic I used red threadlocker to hold the stripped ones in place while I bought a new bolt for the 1 I broke.
Will those bolts ever come out if/when the car reaches 240k miles and needs new spark plugs again?
Red threadlocker needs to be heated to 550F to be removed according to their site.
If I had to guess the bolts will have to be drilled out and the holes will need to be sized up and rethreaded. Either that or a new head will have to be bought. Both of which are rather far away. Took 16 years to reach 120k miles.
