Hey guys, a couple years ago, I bought an 04 F150 5.4 3V for super cheap. Customer didn't want to repair it, so I bought it. Needed the usual 3v stuff, plus some odds and ends.. But, it was a good, clean and relatively rust free truck. Anyway, got it running but had a knock.. Isolated it to #2. Pulled the pan and 2's rod bearing was bad, so put a set of bearings in (crank looked good yet). Drove it but it still had a dull knock to it. Didn't really change with temp and was gone by 1800 rpm. Said screw it and drove it any way. Well it ended up annoying me and it was still making some metal in the oil, so I built another 3v to replace it.
As things go, there was always something more pressing and the new motor sat patiently on its stand for quite some time.. Ended up driving the truck for a couple years/15k miles. Several out of town trips and even an out of state trip or two. Finally pulled it a month or 2 ago now and got the fresh bullet installed. Well the other day I decided to pull the pan and investigate the noise, hoping I could sell the long block. A quick visual showed nothing obvious, but a closer look showed something askew on #1 main. Could see some bearing poking out from the cap. Turing the crank showed bigger problems - the shell was Turing with the crank! Well, guess I'm not selling it as a running engine any more
Pulling the main, I was rewarded with carnage..
