Default symptoms of spun bearings

searched to no avail

I wrecked my car a year ago, finally finished getting her road worthy, I changed the oil and noticed about five pieces of copper shavings in the old oil. I know that this is a symptom of a spun bearing but I was wonding if there was anything else that the motor would do. Since I have been driving it, I have noticed that the engine Idles really rough, somtimes revs over 1K then just dies. There is also a tick coming for the motor. Not valves, not injectors, I have no idea what it is. I was wondering if there is a spun bearing would that cause this loud engine tick? any input is appreciated. Thanks

Yes, bearing damange produces a tick or knocking sound that increases with RPM.

This can only happen if the motor is ran with low/no oil correct? I never ran the car with low oil...I am confused as to why this happened? The car did sit for a year before I drove it. But I primed the motor to get it lubricated....can bearing damage be caused if the timing belt skips?

It can happen under a variety of reasons. low oil is only one way. Even if the car did sit for a year, it generally doesnt do it. Oil is quite filmy, it will give protection (albiet marginal) to the bearings during startup until oil pressure is returned.

I would switch to something else immediately, just too many spun bearing threads running this oil.

Really? Does the oil really matter that much? I read the OIL FAQ Thread which says oil is basically just preference, Mobil was rated according to the FAQ for 2006+ wrx. Motul and Royal Purple are not. What oil would you reccommend I run?

Yes because they all add different additives from different brands.

Speaking from experience. When I used mobile 1, by the time an oil change would come around I found I was missing some oil. Usually 1/2 - 3/4 quart would disappear.

Switched to castrol syntech, saved some money, and what I put in is what I get out.

So it does make a difference. Mobile 1 is too thin, which is why it was disappearing

Yup, I had the exact same symptoms. Been using Syntec for 40k miles now.
