Knock on Bottom End Hey so recently I have been noticing some type of knocking/tick coming from the bottom end. I got it up in the air yesterday at work & confirmed the knocking with two of the techs. They recommended a couple of things but they are Subaru techs so I figure I'd get an opinion from you guys too.

Cut your oil filter open. If you see little gold flakes, then you have spun a bearing. It could be a rod knock too. Either way, bottom end knock=not a good thing.

Yeahh I mean I still have oil pressure for the time being. I was going to probably put a magnet on the bottom of my oil pan hopefully getting some metal flakes (hopefully not but if it is the problem hopefully it will help). If it was a rod knock what would be needed to be replaced? If it's big would I be better off to buy a new engine from GM? I can get a good deal on them.

You really should be able to get your answer if it's a spun bearing by just cutting the oil filter open. If it's rod knock or a spun bearing, it will take some work to get it fixed. I guess it's up to you if you want to put the money/work into a rebuild, or if you just want to buy a new motor. Just make sure that's what it is before you make any decisions.
