Johnny S Posted April 10, 2007 Report Posted April 10, 2007 Well, four of the six spark plugs came out the "normal" way after soaking in a bath of PB Blaster for about 2-3 weeks. A little soaking...a little tapping....a little soaking....a little tapping....repeat. However, the time finally came to give them a little more solid nudging. The good news is that four came out just right. But I only got the top half on the other two. So, the base is still stuck (and still soaking) in the head. It looks like the best technique to get these out will be to weld a bolt into the base of the old spark plug and try again after adding a little heat. Any other ideas that might work? Quote
Don Coatney Posted April 10, 2007 Report Posted April 10, 2007 I had the broken spark plug problem with the Spitfire head I hope to install some day. I used a MAPP gas torch to heat the broken plugs cherry red. I then hit them with candle wax borrowed from my wife (without my wifes knowledge). Let things cool down and they all almost screwed themselves out. Quote
Johnny S Posted April 10, 2007 Author Report Posted April 10, 2007 Don, thanks....did you let the plugs cool a little before applying the wax or did the room fill with smoke and a little fire? Also, was that the wife's special halloween candle? Quote

captden29 Posted April 10, 2007 Report Posted April 10, 2007 i never heard of the candlewax thing. what is that all about? dennis Quote
BobT-47P15 Posted April 10, 2007 Report Posted April 10, 2007 I think it sucks right down into the threads and lubricates things. Quote
Lou Earle Posted April 10, 2007 Report Posted April 10, 2007 Another way- - I had the head off but will work with it on- keep soaking the plugs then wire brush off all rust and crud. Then vacuum it out of area or blow it way with air. then bust off the ceramic and insert a large easy out and drive it in- then twist them out. Then crank engine with plugs out to blow out any debris. I have blown out bolts wshers and my nephews bb's that way Lou Quote
vitamindart Posted April 10, 2007 Report Posted April 10, 2007 i would think welding the bolt should cause enough heat to unscrew them but the candle wax trick is pretty cool Quote
JohnS48plm Posted April 11, 2007 Report Posted April 11, 2007 We always used beeswax in the shop at work. John Quote
