    due to extreme humidity, in the time that i have had the head off to get shaved etc, the bores/ cylinders/ combustion chamber (which should i call it? ::) ) have noticible minor surface rust, now i can wipe it off with a fingertip (so it's not set in) what's the best way of cleaning it off. clean soft rag???

    If you can remove it with your finger, do not sweat it. Wip it off with a rag, and if anything is still there, lightly use a green scotchbrite pad, scuff it clean, and then wipe the bore clean. I would then coat the cylinders and the top of the block with LPS 3, and cover with towel or light shop blanket.


    Good luck!

    Scotchbrite works awesome or any similar product available in your area, you are not going to do any damage by hand, these can be had in the household cleaning stuff or at a paint store. They also make ones that go on an angle grinder or die grinder in different grits. If its gonna sit for a while lather it up with some heavy grease.

    Funny you would say ATF. Makes a lot of sense. it has detergent in it so it should help clean it out. I run ATF in place of oil to clean out motors that are very gunked up. Usually I will run 4-6 series of ATF fillings changing the filter (a cheap one) each time. I run it up to temp then let it idle for a while; around .5 hours then drain and replace. It cleans the crap out of the valve train and seems to help the oil pressure overall.
