Default Re: New m3 and rod bearings

It depends on the severity of the failure. In a catastrophic failure your engine will seize, a rod may get thrown, block may get damaged, lots of oil may dump. If not catastrophic, it will sound terrible and have chewed itself up inside to the extent that it will likely eventually throw a rod. In either case, if it has come this far it could probably mean your engine is beyond repair. The hope is to catch the worn bearings before they reach this point.

How much does it cost you (ballpark number) to get it checked if you don't do it yourself?

There is no way to check other than inspection and the labor is the same as to replace the bearings. Since labor is most of the cost of a rod bearing change, you might as well just change the bearings. The cost for that is typically in the $2-3k range for parts and labor depending on the bearings and bolts used.
