Hey Guys,
I'm considering buying a car that's been sitting a while. It's been garaged and off the road since the 90s, the motor's all intact and complete, but it's locked up from sitting. It's the original motor so I'd like to try and save it. What's the best way to go about doing this? Tear it down to get access to the rings, or should I just keep it together, pull the plugs and fill each cylinder with PB Blaster and let it sit? I've heard people using that, ATF fluid, or diesel fuel, as well. How would you guys go about saving this engine? Thanks!

Cheers

Dave
