Hello, are there any good tricks to getting spark plugs unstuck? I estimate these have been in place for 17-18 years and the engine has not run for over 10.
I tried PB Blaster overnight with no luck on the three on the right side. I've got a long breaker bar but am afraid to put too much torque behind it and break it. I also have an 18V impact wrench but wanted to use that as a last resort. I am not sure how cautious to be.
I read here that someone soaked their plugs with diesel fuel but was curious if there are any other tricks.
Thanks
Bill
