Cracked Head..Need advice

I have a 2005 F250 6.0L and recently found out that the passenger side head was cracked. I am trying to figure out the cheapest way to go on it. My options are replacing the head but the mechanic that looked at it said there's a really good chance of more parts being damaged, replacing the engine, or selling the truck as is. I have no idea what it is worth with a cracked head if someone could give me an idea that would help me out a lot. Just looking for any advice anyone can give me on this. Thanks.

So why are the heads off? If the head is cracked most of the time they can be repaired. If the cracks in the head are just the exhaust valve seats then the seats can be replaced. What other damage could be done??

The heads arent off. It was leaking a lot of oil when I woke up one morning and wasn't starting so had it towed to a mechanic to take a look at it and he call and said it was cracked and wouldn't know if anything else was damaged or not until he got in and took the heads off.

Was it cranking ok? Sounds like a mechanic may be trying to take advantage of you. I would first suspect high pressure oil leak, whether internal, or external. If injectors can't get high pres oil, your truck will never start.

Do you have a way to monitor icp duty cycles and pressures?

yea it sounded like it was cranking fine just not starting up. at first when i talked to him over the phone he thought it might be the IPR valve. My first thought was High Pressure Oil Pump. This is the first time I've taken it to this mechanic I usually use a different guy but he was one of my buddies friends and closer so I thought I'd save money on the tow.

Not all mechanics are the same, you should really take it to someone who knows how to work on powerstrokes/diesels.

K well a cracked head is not going to cause a no start. So what sounds like may have happened is that the STC fitting on the HPOP has failed and blown apart. When this happens it can cause a no start as well as an oil leak. The reason it causes a oil leak is because it blows apart with such force that it blows a hole in the rear cover.

Yea it could be that I was just told that a head was cracked so I thought I would see others opinions since it kind of put me in a tight spot.

Well like I said a "cracked head" is not going to cause a no start. So sounds to me like you need to have the truck taken somewhere else.
