yes be sure to get your tap started straight and check your thread depth because pipe thread is a tapered thread that actually seals on the thread. that is why the sensor will not bottom out into your exhaust manifold

when i was finished drilling and tapping my manifold, i took my shop vac and sealed the area around it and sucked out all the shavings. when i was done, i took the top off and looked in the cart of dust and dirt out of curiousity, and it had a fine layer of soot on the top. along with the shavings, it sucked some of the carbon out too.

i agree i just drilled mine dry and straight up so all the shavings fell down and then i stuck a telescoping magnet into the pipe and got the rest of them then i took a shop vac to the hole. i know its a little paranoid and the shavings that are left will just blow right by the turbo but i diddnt want to take a chance
