Is anyone familiar with the common failure modes of the Lambda II GDI v6 engine from kia?
I have a 2016 Sedona which has received regular premium oil changes for the last 40,000 or so miles. It appeared decently maintained before I got it. I have been picking up metal flakes on the drain plug magnet I put in a few oil changes ago, every oil change. I would love to know what is shedding ferrous particles. (so I can replace it before it dies)
I see used engines are in high demand and there is a lot of internet talk of them blowing up.
I found an extended warranty program, but it is for head bolts/blown head gaskets Kia bulletin I have no indication of head gasket/head bolt problems.
Most stories I see people blame on poor maintenance as the failures can be catastrophic. It seems like they throw rod bearings and keep running until they self destruct? blown bottom end
Does anyone have any insight on the common failure points? I would like to catch it before it grenades. It runs great, its a DOHC variable valve GDI timing chain motor. I have not caught any metal in the filter media. I recently walnut blasted the valves and got the carbon off (however the metal on the drain plug magnet pre-dates this).
If it was a vw: I would replace the high pressure fuel pump/cam parts, if it was a bmw I would replace the rod bearings, my honda benefited from a cam phaser and timing chain change... I can do the work, I just don't want to parts cannon the engine piece by piece. I should have never put in the magnet drain plug I had on the shelf...
