Setting Your Expanding Pilot

1. Select an expanding pilot that is the same diameter as the valve guide ID.
2. Insert the pilot into the valve guide, making sure the expanding section of the pilot (collet) is completely within the valve guide. The pilot will not center properly and may be damaged if the collet extends outside of the valve guide.
3. Pilot shoulder should be about 1/8" above the valve guide.
4. Turn the pilot while holding the nut at the opposite end. This will expand the collet and secure the pilot into position.

NOTE: DO NOT use Expanding Pilots with multi-angle valve seat cutting systems such as 3-D Fast Cut.

Engine Professional Thread Repair Update

The January-March 2018 issue of Engine Professional Magazine from AERA included an excellent article about Thread Repair. If you haven't read it, take some time to do so. 

The article includes a section on the Full-Torque spark plug thread repair system, specifically referencing P/N FT-514LTK. Unfortunately, Goodson doesn't carry this product any longer, but it is still available directly from Full-Torque.

It's always great to be mentioned in an Engine Professional but we want you to be able to find the parts you're looking for so head on over to Full Torque and tell 'em Goodson sent you.

Getting a Grip on Dowel Pin Pullers

I have a confession to make. I’m addicted to social media. That means I watch a lot of how-to videos on YouTube. Some of them are great, but some of them … not so much. I was watching one the other night when the guy used a pair of vise-grips to pull a dowel pin. I wanted to reach through the screen and rip those pliers out of his hands. Yes, he got the dowel out. But he also crushed it (and not in a good way). Let me be clear, you don’t use vise-grips to pull dowels. You use a dowel puller.
