Hey Scotty please help. my 99 Ford explorer 4.0 v6 sohc engine is in trouble. I managed to tear apart the top of the engine and remove the valve cover. Underneath was littered with metal shavings from the timing chain and crank spocket. The guide and casset are both shredded.
It looks as if the 4.0 is non interference, which means the valves are ok. I tried hand cranking the engine and it seemed to turn rather smoothly and freely. Also as a note it seems the previous owner didn't change the oil very much. There wasn't a whole lot of sludge, but the old oil most likely caused this problem.
What should I do? Buy timing kit for 100 bucks or swap it out for a used or reman engine?
I'm also trying to sell the vehicle for around 1500 after it's fixed. I got 700 in it now, so a new engine doesn't fit well here. But if you tell me that's exactly what it needs, I'll absolutely believe it.
