I'm new here, so forgive me if this has been talked about in the past. I have a relatively well running A4 which I really don't want to part with, but I seem to have developed a small crack in the lower part of the block. I have no signs of water intrusion in the upper part, in the cylinders and have great compression, so I hate to just "chuck it". My question and last gasp effort is to see if anyone has had any luck with engine block sealers for small cracks. In reading on the web, there seem to be some good products. So, anyone "been there-done that" with any success. Otherwise, how much am I looking at to buy a used block and just use everything else off my existing engine? Thanks for your time!!!
