My 97 S-10 Blazer started tapping one day and now there is no oil pressure. I paid someone to change the oil pump and it's still doing it... now it sounds like a rod is knocking. What else could the problem be? The Main bearings????????? How hard is that to fix if so?
It sounds like you spun a bearing and it is eroding your crankshaft. It's only a matter of time before you throw a rod.
You have to have your crankshaft and bearings replaced. It's not cheap!
