Timing cover advice needed
Getting started on my 400 rebuild finally. After pulling the timing cover off, it appears that there is a fairly significant? amount of corrosion on the engine side around the water ports. My question is, is it bad enough that I need to go ahead and replace the cover? How common is this issue? Also, I noticed a groove being worn on the inside of the cover by what I am guessing is the cam bolt and eccentric. Thoughts on this as well would be appreciated. Thanks for the help!
