looking at starting some engine repairs to my 2001 Ranger. About two weeks ago, driving on the highway, out of nowhere I get a clicking/ticking noise coming from the drivers side of the engine, power loss, and extremely poor idle once stopped at a red light. By the time I got it home, pulled into the driveway, idled erratically and shut off.
The next day, checked spark plugs (good), cables (good), coil pack (old but good), air filter (good), IAC valve (good), throttle body (dirty, but wasn't issue), checked for vacuum leak (none found), and fuel pressure was good. Being dumb I disconnected battery and got rid of the hard codes it was showing with a flashing check engine light the night before.
Took it to Ford dealership, they checked it out, did a relative compression test and found cylinder #6 was showing a 38% difference compared to the other 5 cylinders. They believe most likely a burnt exhaust valve and are suggesting an engine replacement due to mileage on engine (220,000).
I've always taken good care of the truck, kept oil/filter changed, never has run hot, and just want to check all avenues before giving up and getting rid of it or getting a new engine.
Am looking at checking/changing the lifters, maybe checking for a broken valve spring, also looking at maybe replacing the top heads/gaskets, and hoping the bottom is strong enough to take it. Really just trying to get this truck to last another 2 years while I finish up school and I would be a happy man.
Thought I would check with the fine experts here to see other opinions, and thoughts on what I am considering.
Posted videos of the truck driving, and in park to get some idea of what it's doing.
Appreciate all advise.
