I'm a newbie to the site, but I'm glad to be here. I have a quick question. I am thinking of getting a rebuild kit for my 85 K5 Blazer, but I can't decide whether the knock i'm getting from my engine is worth the effort. It doesn't seem to knock when it first starts up, but as it gets warmer, it gets louder. By loud, I don't mean extremely loud, but loud enough to where you know it's there. My engine doesn't run any different since it started knocking, I can still fully accelerate and I don't seem to notice a loss of power...it just knocks. Any suggestions as to the type of knock that could be categorized? Thanks!
