exhaust blowing at headers.....

[Disorderlypunk]

when i did my head rebuild about 5 of the studs snapped (after a week of plus gas and the wax trick)
all i could do was put the head in the pillar drill to pilot drill the snapped studs and use an extractor tool
some did need a thread repair insert as removal was not an option so had to drill out rather than remove
if you havent got the tools/confidence to do this have a look around for a local engineer shop (NOT A MECHANIC)
its pretty simple for engineers to deal with and a lot cheaper than getting a mechanic to do it.


so for the new studs - i would use loctite 222/242 as it is low/medium strength and only there to reduce galling
DO NOT USE RED as if you need to remove the studs in the future you will hate yourself
