Timeline of what happened:
- Bought 1991 Ford Explorer 4.0 ohv / 5spd in January 2021 in good condition.
- Starter gives out a couple months later, seemingly just due to age. Replaced it with a napa reman. All is fine for a few months.
- Engine starts having a pinging issue under load, Replaced every potential cause, maf sensor, intake gaskets, decarbon treatment, etc etc. none of which solved the issue.
- Replaced spark plugs (autolite) with Motorcrafts, engine immediately stops pinging, but on the first start with new plugs something sounds like its not meshing right. A couple days later, flywheel teeth have broken off. I checked the firing order/wires many many times.
- Replaced flywheel, replaced starter, all is fine for a couple days then it starts making bad noises again. A month later, the flywheel teeth are broken off again. Thats where we are now.
What I think may be the problem and why — this is why I’m posting, please tell me what you think about this:
I’m suspect of the timing chain. I think it may have jumped, causing the pinging/detonation problem.
I think the advanced timing may have caused the engine to kick back onto the starter, breaking and grinding flywheel teeth. Another symptom that leads me to the timing chain is excessive oil usage, with no obvious leaks or smoke from the exhaust.
I’m basically waiting and deciding whether I truly want to keep dumping money into thsi truck. Not much else is wrong with it aside from the repeated flywheel destruction.
Tell me what you think, I’m looking for any possible ideas.
