A gentle reminder of why regular oil changes are important.......

That's really not too terrible all things considered. I cleaned out an Olds 350 years ago that was so bad, the intake valley was slam full up to the top. When I removed the intake and valley pan, you would have sworn the valley pan was still there. I cleaned it all out, put a new set of lifters in it, new rocker hold downs, changed the oil and filter, added a can of Engine Restore and it ran better than it had since it was new. That was the worst one I have still ever seen. We put it all on a bathroom scale and it was a tick over 3 pounds of sludge.
