[QUOTE="ford141, post: 998301, member: 7112"] The EGR was only turned off with the H&S but was still there up until about a month ago when I did the No Limit CAC pipe since I had the truck apart for accident repairs. But the gaskets were already leaking and I only drove it about 20 miles with the EGR deleted fully before I tore it down to this point. Didn't tow with it or run it hard during that 20 miles, only drove it home and back to the shop. Unfortunately I did not monitor ebp when it threw the code. That was my dumb fault. So this is what I'm looking at right now to remedy this problem: 1. Replace cracked piston with factory stocker. 2. Valve spring/pushrod upgrade. 3. Wastegate I'd really like to upgrade the pistons while I'm in there, but I honestly don't plan to run this motor hard. I'm 100% sure that my cracked piston is due to valve contact. If I remedy the valve contact with springs and a wg, I'm thinking it will live a very happy life for a long time while I have it. Morgan, I will be in touch, but I have to save some money first. I didn't budget this much into my head gasket repair job. [/QUOTE]
