ceramic coated headers on break in

mine did survive !!!

the problem as I think is during breaking time the timing isnt right
the exhaust gas are way hotter and the headers turn red on some engine
because of it,the fresh coating isnt hard enough to keep the heat

so moment the engine is starting get the timing as close the fastest you can
and of course that true oïl and prestone arent good for that coating

for mine they survive the new engine but didnt survive the rust
