thanks for all the advice. this is a great forum.

i didn't take the head off. i tapped the hole already. i used a shop vac connected to a smaller hose to suck up as much of the shavings as i coud. i then disconnected the other spark plug wires and i cranked the engine a few times to blow out any residual shavings. i didn't see anything come out though.

right now, i'm just waiting for the rtv silicone that i applied on the insert to dry before i put in a spark plug and start her up. the dry time says 24 hours on the package so i'll let you all know what happens then.

if something goes kabloom...i'll be reading up on the 3.4 5vz-fe swap. <img src="/forums/images/graemlins/lol.gif" alt="" />
