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?No Oil Pressure.....Is it the Main Bearings ?
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!No Oil Pressure.....Is it the Main Bearings ?
if the oil pump is driven by the distributor gear the shaft that connects them or the gear itself may be damaged. shouldn' t be the bearings thoughNo Oil Pressure.....Is it the Main Bearings ?
Sounds like the oil pump or the cam gear that runs the oil pump failed. Either way, running an engine without adequate oil pressure can ruin both the rod bearings and the main bearings and ruin the crankshaft. Very expensive to fix since the engine needs a complete overhaul.No Oil Pressure.....Is it the Main Bearings ?
pistons are wore out, rings are old maybe or brokeNo Oil Pressure.....Is it the Main Bearings ?
Oil pressure system in any vehicle is not only the oil pump is also the seals on your pistons, you head, etc... Have a compression test done on the engine, and take it from there.
