[QUOTE="Catmonkey, post: 13424567, member: 124025"] I'm in the process of changing out my short block from what ended up being a blown head gasket. After a loss in compression in the 7 and 8 cylinders, I knew the engine had to come out and it was going to go back together with better components. When FRPP announced the part number for the '13 5.8 aluminum block, I opted to go that route. Here's a pic of the head gasket on the engine. The top part of the gasket is what gave way and left a nasty looking spot on the head at the break. [ATTACH=full]500596[/ATTACH] While I was in the process of stripping down the heads so I could have them resurfaced, I spotted this little faux pas. [ATTACH=full]500597[/ATTACH] For those of you that might not be familiar with engines, there is only one keeper on the valve retainer on the exhaust valve in the center of the photo. There should be two. I managed to find the other keeper in the pan. While it may be possible for this to have happened while running, it would be pretty rare. This engine only has 4,000 miles on it and hasn't been over-revved. Not something you want to see in these high-dollar engines. Once the cam followers are in place you'd never see this. Lucky I didn't drop a valve. [/QUOTE]
