Hi,
On my Toyota Corolla exhaust manifold there is a heat shield mounted by means of four M6 screws. Thats approx 1/4" screws.
When I need to access the oil filter this heat shield needs to be removed which happens approx 1x pr year.
I ALWAYS struggled to undo these 4 screws and I always feared that they would break.
I tried copper, aluminium and nickel anti seize to no avail. Now 1 of the screws broke off and basically I need to pull the entire manifold to drill it out again.
Is there a product that will function in this environment? I think it's crazy that even 3M Nickel Anti seize gets completely stuck after just 1 year and maybe 10000 miles.
Copper and Aluminium for sure don't work either.
Will titanium screws work?
