bobgil 34 Posted March 13, 2015 Help I bought this 2001 cx613 E7 427 last August. I noticed a small what I though was an oil leak making the top of the air compressor wet over time. I can wash it and it takes about 3000 miles and it has the compressor wet again. I have run over 50000 miles it runs and pulls good and is doing over 6.75 mpg but it pulls with the 2012 Cummins 485 that the other drivers are running with the same basic gearing.I decided I would check out the leak a little closer and see if I could tighten a line or something to stop it when I found the fuel was leaking from between the head at the number 4 Cylinder and running down the side of the block and onto the air compressor. A body got any idea what I might be up against and what it might take to fix it? Should I keep running it or park it until I can get it into a shop.Bob Quote Share this post Link to post Share on other sites
