99 expedition with 5.4L ~205,000 miles. Drive everyday. Sudden loud engine noise sounds like steel bouncing around. I noted metal in a fresh oil change, none in past changes. Oil looks like it has glitter in it. The coolant is brown and smells of oil, oil is somewhat milky. At the same ~time the radiator has started to leak on top near hose. Oil consumsion has increased. The engine noise is on both idle in hot and cold engine and on acceleration, decceleration. I think I may have a beent rod that is getting chewed up. I am torn the remanufactured engine and labor is 5800$. Has anyone used a promar engine they are here in NJ. 2200$ for their remanufactured engine. Is this engine repairable? Thank you much for your help.

 

Sounds like a headgasket leak has caused a cylinder to Hydaulic (coolant can't compress so the rod gives and bends) . I can probably be rebuilt, but buying a reman engine gives you a warranty.
