In my neck of the woods MMO is everywhere even engine oil is better than nothing i would soak it for a few hours or overnight. I would remove the valve cover and check valve clearance if rockers look dry and crusty pour a lil bit of diesel fuel over it and hand crank the engine making sure all rockers are free.Don't worry, I haven't started on anything mechanical yet. I've messed around with old cars for a while and definitely have made some silly mistakes in the past. Do you prefer MMO over Kano Kroil?
I plan on getting started this weekend. I still have to get one of my other projects out of the driveway.
