I have my engine (14000 miles) apart and reground the valves by hand today. The valves/guides/springs are in specification. I noticed one cylinder has a light rust coating about 3 cm from the top, presumably where the pistons were left during their many years of storage. The rust layer is very thin without any pitting or flaking. Like the fine rust layer you see on old tools and drill chucks.
My Question: Could I use a rust removal treatment followed by a very light and quick hone (approximately 10 seconds) to break the glaze and then put the original pistons and rings back in? What are your feelings regarding this?
Thank you for your comments.
Note: I do not really want to rebore and go to the 1st over.
