I was driving down the road late at night and the engine seized. I wasn't able to turn it over, but came out the next day and was able to turn it over. I had it towed to my house after I did a quick walk around and found oil everywhere on the underside of the truck. It sounded like crap when I started it for a couple of seconds. The dipstick was absolutely empty and I noticed the turbo fins are hitting the side of the housing. I disconnected the intake pipe from the turbo and added oil. I didn't see any oil in the turbo's charge pipes. I started it for a second then I heard a clunk on startup, but it sounded OK. I shut it off quickly, but I noticed when I walked around that it dumped all the oil of the engine. It looks like it's coming from the oil filter/cooler side of the engine, but I can't see at this point. It's not coming from the oil intake on the turbo. I'm guessing the engine is toast even though it sounded OK on startup? I hate to dump money in a new hx30 if the engine is junk. I might just go find a 6bt and slap it in. 4bts are very hard to find around here. I hope you guys are having a better weekend than me!
