My truck was quite, ran hard a couple of times "WOT Runs" now I can hear a knocking sound that is constant at all rpms, loud at idle & louder under throttle.
Sounds slightly louder on drivers side.
When I let off the gas the injectors kill & you can still hear it, but it is muted somewhat untill idle then it gets louder.
Have not ran codes but no CEL.
Don't the injectors click off completely after you let off throttle? Or could an injector cause this kind of sound.
How loud is a rod or wrist pin?
I was running it hard to find weak links since this truck is gonna pull a lot of weight cross country. Guess I found one.
Truck history 1st owner towed a horse trailer fifth wheel with a jakebrake or ebpv brake setup , a chip & downpipe.
2nd owner would pull a utility trailer around.
230K miles & tranny finally going out.
So to me even though it was a work truck seems too me like they took care of it. To the best of my knowlage these trannys don't usualy go past 200K when towing so if tranny lasted this long, can it be possible the engine was abused?? Stupid question I know but I'm trying to figure if I'll be able to get another 200K outta this thing.
Here are some vids of the sound:
