OB99W Posted July 1, 2010 Share Posted July 1, 2010 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? Quote Link to comment Share on other sites More sharing options...

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. Quote Link to comment Share on other sites More sharing options...
nipper Posted July 1, 2010 Share Posted July 1, 2010 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? Quote Link to comment Share on other sites More sharing options...
kirbykirb Posted July 2, 2010 Author Share Posted July 2, 2010 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.

nipper Posted July 2, 2010 Share Posted July 2, 2010 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.

GeneralDisorder Posted July 2, 2010 Share Posted July 2, 2010 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.

Fairtax4me Posted July 2, 2010 Share Posted July 2, 2010 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. Quote Link to comment Share on other sites More sharing options...

The car drives fine ironically, I took it up to 60 to see if I'll get stranded. 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!

GeneralDisorder Posted July 2, 2010 Share Posted July 2, 2010 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 Quote Link to comment Share on other sites More sharing options...

I TRIED TO SEE IF I COULD KILL IT and make the engine ASPLODE AND NOTHING. but going to switch over a different shortblock! Quote Link to comment Share on other sites More sharing options...
aa8jzdial Posted July 5, 2010 Share Posted July 5, 2010 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.
