ASHLEY G 0 Posted April 9, 2011 Afternoon all! I've just started up my newly rebuilt engine for the 1st time ever, and on running it up to temp, I've noticed there's a colant leak from the front right head nut. (using ARP head bolts) Does anyone have any idea why I'd have a coolant leak from here? It's seeping out from the nut between the nut and the head! The engine was already built up when I bought it so I have no idea what torque the head was bolted on at. I'm hoping this can be easily resolved Ash Quote Share this post Link to post Share on other sites
