Interesting DIY test on penetrating oil. Guy has some other neat videos, something to watch when its too cold to wrench! Part 1 Part 2 Note the neat torque meter!
Informative; I like "any penetrant better than nothing"..... Heat seems also to be a good friend. Info all of us can use; thanks for sharing!
I PB blasted the hell out of the three bolts that hold the battery tray to the core support, yesterday and will give it a week to soak. I'm hoping the extraction sockets Dave Johnson let me borrow prove as fruitful as the dozen or so videos I've watched with guys using the same ones. This video is encouraging:
I thought the project farm guy was funny when he said "who would wait 3 hours for the oil to work?" - we wait days!!!
Brett, those extractor sockets work great. I only wish they had ones you can tighten worn out bolts with!
