When working with dissimilar metals like aluminum head and steel spark plug body - heat is your best friend.
Do the penetrating oil - pump juice thing 1st. If that fails . . . Then use heat (lots of it). Because the aluminum head is finned and because aluminum conducts heat so well you will need flame - like MAPP gas. A heat gun isn’t going to be enough. Heating the aluminum around the plug causes the hole to expand, breaking corrosion, and reduces the tendency to have the threads binding and galling. Going to be a tough gig with engine tin in place / installed. But if the penetrating lube solutions don’t do it alone, heat will. Way easier to do with the head sitting on the bench. |
