Ok, it happens for various reasons, water can get into engines and water on unprotected steel = rust.
I recently pulled my old Stealth SOHC engine apart that Jordan still owned, he had left it sitting in the dirt uncovered and rain could go right into the lower intake manifold.
Rust was BAD. Some work to scrape cyl walls and get pistons out the top, my goal was to salvage possibly pistons but mainly rods and crankshaft.
I recently also pulled the head off my Talon to fix, it overheated bad warping the head a few months ago and has just been sitting that way.
Well, I guess from driving the car just a few more times at the end, and from topping off plain water in cooling system to keep it going for a few more miles.... coolant in engine was mostly water alone and of course some of it pooled on top of pistons as car just sat... THIS caused rust.
Not to the point of having to dis-assemble the bottom end again I believe, but requires some good cleanup now and requires oil/filter changed quickly a couple times after I get it running again.
My question, after I carefully scrape surface rust from cyl walls, what is the best sandpaper to hit those rust spots with lightly?
1,000 grit or 1,500 grit or emery cloth?
