Red - Should be fine. Make sure you clean out the metal shavings really well...don't want them getting to your bearings. Use tapping fluid or oil to lube the NPT tap...take your time, the block is fairly hard.

Ok thanks man!

It would be a lot easier to use the adapter Slow posted above though



LOL...yeah, this thread went off on a couple different tangents!

I use wheel bearing grease on the tap to help catch the chips and I plug the compressor into one of the other port and supply it with 4psi to keep them out of the main gallery.

Done a bunch of blocks this way with no issues ever.

most senders are roughly the same size as the current hole. You can't just re-tap, as you will be cross-cutting the threads that are currently in there (no chance in hell of sealing these threads). What you would need to do is get a thread adapter that has a minor thread diameter bigger than the max thread diameter of the female threads, and drill/tap a new hole based upon the new threads.

Thanks for the clarification.

Awesome! when i used aaron's exhaust stud kit, i had some cutting fluid left over, but grease sounds better...im just glad this happened with the motor on the stand and not in the car.

Even better!

Start the tap square to the hole then tilt the stand so the Tap is down and let gravity help
