Yesterday my trusty pathfinder suffered a pretty bad engine failure. Blew the dipstick out along with a bunch of oil, along with a pretty significant loss in power.
Ive dropped the remainder of the oil (3.5l) and replaced it.
Engine then started and seemed to be running on 3 cylinders. the engine did idle but shaking about. When it was running I removed the dipstick and there was pulsatile gas coming out - presumably blow by?
Ive been told that a failed injector can cut a hole in the piston and cause this. Do you think this is what has happened? Any other ideas?
At this stage im looking to buy a wrecked vehicle for a donor engine.
Some videos of it running
Thanks for any assistance!
