Getting knocking/ticking at engine 2000 Ford Ranger 4.0L V6 OHV. The truck doesn't overheat or throw codes..just constant ticking.

Oil gauge show pressure....Is there a procedure to remove the timing chain covers [without removing engine] for inspection?

I'm thinking these need to be replaced.

Thanks,

Mike

 

You can see a decent amount of the guides by pulling the valve covers. I pulled my passenger side valve cover to inspect a rattle and found the guide snapped off inside the head. Still gotta pull the engine to replace them, but at least you can see the issue first.

 

You have a 4.0l OHV engine NOT a 4.0l SOHC
So timing chain(only 1) was not an issue on these engines

A "tick" noise is from valve train and usually a collapsed lifter, annoying but not a major issue, on the 4.0l OHV you have to pull the heads but not the engine, to replace lifters

A "knock" is different, lower tone and can be felt in the engine block, get a wooden stick like a short broom handle, start engine, place wood end against block or head and listen at the other end, you WILL hear a Rod or Crank bearing knock plain as day
"ticks" from valve train are way different, and wouldn't be heard thru block

 

Thanks for the advice. I’ll take a loo.
