Sudden loud rattle from engine while driving

Postby Bruce » Mon Jul 01, 2019 11:30 am

I was coming home from a camp yesterday, on highway approx 100km/h and car performing normally.. no odd sounds, no indicators, no overheating when suddenly while under acceleration I hear a loud high pitched rattle from the engine. I pull over immediately and as the cars slows to idle I hear it rattling like crazy. Turned off engine, opened bonnet to have a look underneath.. Nothing unusual to see so start it up and there again is that awful loud rattle that seems to be coming from the front of the engine. No good can come from running it like that so I turned it off and called for a tow.
It's being brought back to Canberra from Bega today,. directly to my usual mechanic. Very annoyed as I just got the car back after spending $2000 on full service, manifold gasket replacement (required re-machining surfaces), and fuel filter. Not that I think it's related but was hoping not to be spending more $$$ on it again so soon.

I've no idea what the problem is. Timing chain was upgraded at 150,000km (it's now 250,000) and been well maintained all its life. Engine starts easy and runs but with that sound I doubt it would run for long. I will find out soon enough but wondering if anyone has an idea what it might be.

Big end material found in oil. Engine a write off!

Has anyone replaced thier Pathfinder engine? What did it cost and would you recommend it?

or should I be looking at a new car?

I'm advised it's not worth it because a) it's a big job, b) there might be an underlying issue and c) metal in the oil may have caused other damage. I'm getting engine swapped with a used one that's done 100,000km. Car not worth much more than the cost of this but I can't afford to scrap it and replace. This way I can drive it a few more years then trade it on something new.
