SPARK PLUG TUBE-ECTOMY
When removing spark plug tubes from heads like the Chrysler Magnum’s, it is important to not damage the tube if you want to reuse them and have a secure fit. These heads have usually been in service for a while and will have a rusty bond to the cylinder head. I usually soak them in penetrating oil and give them some light taps to help the oil do it’s job. Then I find something like a large socket or piece of dowel that will fit snugly inside the I.D. of the tube to help prevent crushing the tube when I grab them with a large pair of pliers or channel locks. If the penetrate has done it’s job, a gentle twist is all it will take to pull them out. Undamaged tubes will easily tap right back in after the head and tubes have been cleaned.
