Re: Oil Pressure went to almost zeroPosted by Bob on February 07, 2005 at 08:19:21 from (66.163.134.177): In Reply to: Oil Pressure went to almost zero posted by ed1 on February 07, 2005 at 08:02:08: It is POSSIBLE, if a rocker arm breaks or a pushrod bends, etc., for one of the hydraulic lifters to pop out of it's bore, causing a big internal oil leak in the engine. You need to start by taking the valve cover(s) off (the one on the side of the engine that was first making the noise, if possible), or both of them and check out the valve action. Of course, it is also possible there is a bearing failure, or oil pump failure (could be a broken oil pickup tube) causing very low oil pressure, and the lifters have collapsed, causing the poor running and valve noise.
