Good Morning Group, I managed to get the push rod out last night without much difficulty. I used a wood chisel to pry it out. After a small burr cleared the hole, it came right out. It was worn down by about 1/4 inch from the top of the rod. I pulled a valve cover and found out why the rod was worn. There was no oil on top of the engine. This explains the lifter chatter, too. I pulled the rods and lifters and there is no visible signs of excessive wear, as a matter of fact, there are no signs of any wear except on that push rod. So in addition to needing a pump push rod, looks like I'm gonna need a new oil pump too. I'm going to check the Rockwell on the push rod, does anyone know what the spec is for hardness of the rod? Thanks for all the advice and tips, Mark Souders > -----Original Message----- > From: elmer tuuri [SMTP:eltuuri@xxxx] > Sent: Tuesday, May 20, 2003 10:20 PM > To: crossram@xxxx; Chrysler300@xxxxxxxxxxxxxxx > Subject: Re: [Chrysler300] 300H Fuel problem - answer > > Does a worn pushrod make noise [knock]?
