Mackken

It had a broken valve and crack in the liner. Replaced the whole engine and gonna rebuild this one for spare since we have more then 1 of these trucks

2014 truck was running great then started missing and low coolant light came on. Oil is way over full with coolant. Towed it home and there’s coolant coming from turbo exhaust output but don’t think it’s the turbo. Tried pressure testing and won’t hold any pressure and have pulled egr cooler inlet and outlet they are dry. Injector cups? What’s most common with these?
