I have a 1983 Cat 30 with a Universal 5411 deisel engine. For several years, it wan't used, and I was told that the rings aren't sealing properly and that compression is down on the No. 2 cylinder is down. I know that there are oil additaves for cars that help to in situations like this. Are there any ones for diesels? Will they work on a boa diesel? I know the long tern solution is repower or rebuild, but I'd like to hold off as long as possible. The engine "sounds" OK, but the power just ins't as good as it used to be. Any helpful hints would be appriciated...
