Or is there a way to minimize/prevent this while leaving the mainifold on the engine. Getting the exhaust mainifold is a pain in the buttocks.....
Also is there a particular spot on the mainifold I should install the probe?

Take the turbo off, use a vacuum cleaner, when drilling vacuum the chips from the outside to the point of penetration, switch the vacuum to the inside, continue with the vacuum inside until you are finished. Coat your tap with grease to aid in cutting as well to trap the chips, wipe everything with a clean rag. Install the EGT probe, hook up the turbo and you are finished.
