Huh?
Anybody have any ideas for me about how to remove siezed up spark plugs from aluminum heads?
This is on the Harley which has sat for 20 years.
For 10 days now I've been squirting a bit of PB Blaster on the plugs 2 or 3 times a day. A few days ago I tried to remove them, one felt scary but reasonable but the other feels like it is rending metal rather than unscrewing. I have continued soaking them, but it still doesn't feel right. I have only turned them maybe a 16th of a turn. I have no idea if they have heli-coils, that is not uncommon on old short plug Harley heads.
You think heating them with a torch & then letting them cool a bit might help? Or heating the head around them?
I can pull the heads with them in, but I'd like to get them out so I can fill the cylinder with solvent first.
