Yes , thanks. I have extracted 4. Blown out the holes. I think one small piece of porcelain is in one cylinder and maybe a little material from the ground strap. Other than that I have plugs out as expected. Just not sure how critical it is to get every bit out from piston tops. I’ve seen posts that say it will blow out. I’m not sure I like hoping for that to do the trick. About to tackle the other fourExtract what is left of the plug first, did you see my link?
The NAPA version uses a threaded puller, I think it's more reliable than the Lisle which is self tapping. That also, is covered in my link and might give you some options. My Lisle only lasted 4 plugs, so you're ahead of my game. Just make sure you replace those plugs with 1 piece units.Please stand buy as I wait for another extraction tool. The threads on the pusher body failed on plug 5. I ordered a second tool. One for me and one to replace the broken one I borrowed. Why did I think I could slap a car together in a reasonable amount of time
