Default Re: Causes of 2100 RPM engine vibration.

Already found out I loose oil pressure ( 0 PSI) on right hand sweeping turns at 45 MPH if the oil level is down one quart. The oil pump becomes uncovered when the oil in the pan moves to the left side on a right hand turn. So lowering the oil level is not an option to lessen my rear main seal oil leak. The pressure recovers when you exit the turn. I have been thinking of adding a front-to-back baffle to the bottom of the dipper tray to prevent this. Not a good feeling to see the oil pressure drop from 35 PSI to 0. I did use the "rear main janitor" on my trip to Maine and I lost/collected about 6 ozs. of oil in 10 hours of driving. The leak wasn't as bad as I first thought. Myself and my driving partner split a quart of oil after two days of driving. I'm still thinking of adding the chevy rear seal to eliminate the leak!!!!
