July 1, 201015 yr Sorry about your loss! Inquiring minds want to know details -- I'm not exactly sure how to interpret your thread title. How did you determine a rod bearing has failed? Did the failure occur after an oil change, or did you find metal while draining the oil? Had you used any Sea Foam, MMO, etc., in the oil? How long ago was the last oil change? What brand and grade of oil was used? What brand and part number of oil filter?

What brand and grade of oil was used? What brand and part number of oil filter? It occured after oil change, drained oil (pretty black) and filled it up w/ 5 quarts. DEADED! IT SPUN! No metal found in oil. Nothing obvious anyway. No seafoam/mmo in it. Bout an year ago (not many miles on it btw.) 10W-40 was oil put in. Previous was 5W-20. Brand was the advanced autoparts special.
July 1, 201015 yr So this car got once a year oil changes? When owining a car you go by mileage or the calander, whichever is shorter. How many miles on this car?
July 2, 201015 yr Author So this car got once a year oil changes? When owining a car you go by mileage or the calander, whichever is shorter. How many miles on this car? Less then 1500 miles/year. And a bit shy of 140K. Startup is what kills most engines; and it killed mine.
July 2, 201015 yr thats an oil chnage ever 7.5 months, and for cars that spent a lot of time sitting i would suggest every 5 months. Low mileage can kill a cars as fast if not faster then high mileage if not properly taken care of. This doesnt happne just because you started the car, this had been developing for some time.

July 2, 201015 yr I would pull the engine - I'm not convinced that's a bearing. Rod bearings typically don't come and go like that - broken flex-plate maybe? Timing belt components...... And for the reccord - rod bearings don't typically "spin". They just wear to the point of being sloppy and eventually they fly apart. That's not something that happens overnight or immediately following an oil change. GD
July 2, 201015 yr Agree with GD. That doesn't sound like any bearing I've ever heard. Sounds more like a socket dropped down the access hole for the flex plate.

I didn't. By fine, I mean it runs and doesn't overheat; my reasoning was: never happened to me before wanted to test engine failure complete. AND IT WOULDNT DIE LOL SUBARU!
July 2, 201015 yr If you took it up to 60 with that loud of a noise it's not a rod bearing. It would have thrown it out the top of the block. I've seen it several times and done it once myself. GD

I've seen it several times and done it once myself. GD This is true, took it up to 70 or so and nothing. I TRIED TO SEE IF I COULD KILL IT and make the engine ASPLODE AND NOTHING. but going to switch over a different shortblock!
July 5, 201015 yr Won't a bad rod bearing become louder under load? Idling is the least stressful on it. When this thing was dropped in gear the clattering did not become louder. My daughter's recently purchased 2004 Impreza lost a rod bearing. I tore it apart Saturday night just to make sure of the diagnosis. #3 cylinder. 110k miles. 2.5 L Oil change history is unknown. Subaru bottom ends are about bullet proof I told her when she first described her problem. I'd sure like to find a fleet of low mileage Gen 1s somewhere.
