6.4L Idles fine, no throttle response and dies when put in gear

Bought a 2008 6.4 with 141k from auction that is a repo. Batteries were pulled and a terminal broke, so when we put new ones in it was locked out and needed a reprogram to turn over. Took the truck to the ford house to get a new key cut and key program.

Truck fired right up and sounded great, no missing not ticking/knocking. Went to put it in gear and the truck died. Started right back up, still sounded great, absolutely no throttle response; pedal did nothing. Put into gear, dies. Fired it once again, sounded great still, checked gauges this time, no oil pressure. No engine lights. Checked the oil again for metal shavings, clean oil.

Not knowing much about the 6.4L, I let ford diagnose the issue for me. Symptoms came back with no oil pressure, 4, 6, 7, 8 cylinders relatively low compression(they called them dead cylinders), #8 glow plug bad, oil or fuel in exhaust(how can you not tell the difference?). Diagnosis: "more than likely a lifter is bad and needs a new engine."

You mean to tell me my motor sounds perfect when its idling and you want to replace it for $11,000? Shouldnt there be a throttle response? shouldnt the motor sound like someone threw a wrench in there? shouldnt there be metal shavings in the oil?

We had a yukon that did the similar and it needed to be reprogrammed at the dealership, they told me thats not the problem. I could also see it being an oil pump gone bad.

I searches a few different forums for someone with this issue and found nothing. Anyone seen this before? Any ideas on the problem?? Thanks yall

My truck had those symptoms when the lower intercooler hose blew off. As for the lifter, when mine died there were shavings in the oil and it sounded like someone was playing a tiny drum through the air filter..

The intercooler hose sounds interesting, but I would still think there would be throttle response if that was it. It should atleast pick up rpms a little instead of idling, right? The truck is at another diesel mechanic so I cant check that right now.

I know nothing about 6.4's but when my 6.0 did that it was a struck open EGR valve.

Mine acted like the throttle was disconnected. Nothing at all when the pedal was pushed.
