I just bought a 2008 6.4 95k miles. W/cheap EGR delete(cap at second cooler only)
Drove it home and noticed low coolant level and no heat in the cabin, when I added fluid and took it for a drive I found that the radiator was leaking. I replaced the radiator and two drives later the water pump went out.
I replaced the water pump and thermostats and drove it. Then found the degas bottle over flowing.
I also noticed white smoke out the exhaust once engine heated up.
I installed a pressure gauge on the 3/8 coolant line and drove around. I was at 5psi until I brought my boost over 20psi and I saw the pressure in the coolant system go to the same boost pressure.(20psi) and then drop to 15-16(cap pressure)
I figure it was my HG. Is there any way that it could be the ****ting EGR delete? Both coolers are still there and coolant is still going through them, there is just a welded cap at the end of the lower cooler. I thought maybe the boost pressure was entering the coolant system from the EGR coolers?
Moving forward, I took the truck to the shop and had the head gaskets check. They found no issues with the head gaskets. While the truck was at the shop they where running it on a hill for an hour(not sure why) and oil started leaking out the exhaust. They let it run longer and it created a puddle of oil out the exhaust.
I was going to have him do the turbos but was scared that it could be a piston after readying forums. I had him remove the oil cap the next day. He said engine cold the cap would stay but once the engine warmed up there was a lot of blowby.(cap would not stay)
Am I to drive this truck off a cliff or what?
Im now looking for a motor, is this the right route to go or should I get another opinion?
Sorry guys that was a lot to digest!
