Question about 2007 Cadillac Escalade Two-Wheel Drive
Could be the oil pump has failed grinding sound then knocking sound could also be the timing is out or failing that something forren has got into the engine. check all these out and don't run the engine you are making the engine worse. if pump for the oil has gone and the engine has been run can mean a new engine. if timing belt has moved could be a new head will be needed. and pistons. failed oil pump does more damage in the long run as the hole engine needs oil.

Sometimes collapsed lifters or loose rocker arms can cause knocking sounds in an engine. However, the fact that there was a possible loss of oil pressure and that the knocking gets louder as the rpm's increase, would indicate that there is damage to a connecting rod bearing and possibly the crankshaft. If the latter is the case you are looking at a fairly substantial repair bill.
