New Turbo & Actuator, 3 miles down , new camshaft??

[Chamberpains]

That oil almost looks burnt. That is a serious shade of black. What were the oil and coolant temps running at. Any idea what the oil change intervals were on it.

No doubt that cam is shot. That's from no changing the oil enough. Grime grinds away at the cam lobes.

This engine was neglected bad. Someone didn't change the oil in it. What a shame.

Just to ease your mind for a minute (and only a minute) there's still nothing definitive that warrants an overhaul. BUT... you need to absolutely do some tests before you just throw a cam in it and button it back up. You need to make damn sure your not wasting your time just replacing the cam only to have to pull it all back apart because there is a major underlying problem in or under the head.

The oil pan needs do be dropped and the bottom end needs to be looked at. Carbon packing is gonna be an issue. You need to see how bad it is. You also need to see what you can see on all the cylinders. Make sure nothing stands out with any of them as far as scars and scrubbing. Make sure you don't have any scary pieces of metal in the pan. Take good clear pictures of the cylinders and the bottom end and post them. Then you'll NEED to pressurize the cooling system to 20 psi and leave it sit overnight. You'll be checking for a dropped liner or problems with the head or head gasket. Rawze shows a good bit of what to look for as far as searching for coolant down there in this video of his overhaul. https://youtu.be/yzQH_Utawis
