mrsmackpaul Posted November 26, 2018 Share Posted November 26, 2018 I was helping a mate pull one of these motors out of his Toyota Landcruiser yesterday Anyway we pulled the motor right apart and his son who is engine machinist is going rebuild it After we had it all apart I was watching a YouTube video on these motors and it says that the push rods are harder one end than the other and to mark the push rods as they come out Well we never did oop's Does anyone on here know of a way pf checking push rods to find which end is the hard end ?? And if not , how critical is it with push rods ???? The You tube video that mentions about the push rods Any advise or help appricated Paul Quote Link to comment Share on other sites More sharing options...
h67st Posted November 26, 2018 Share Posted November 26, 2018 If they really are different, GM should have marked the harder end. I don't know a thing about the 6.2. Quote Link to comment Share on other sites More sharing options...
Quickfarms Posted November 27, 2018 Share Posted November 27, 2018 I found this description for the pushrods This pushrod has an actual length of 8.845 inches. It is made of .375 diameter steel tube. It is tipped with one welded .375 diameter M-4 tungsten steel ball (copper flashed with hole) and one welded .375 diameter steel ball (with hole).According to this description the copper flashed end is the hard end. How long the copper will last is anyone's guess but they are probably really just worried about the assembly line 2 Quote Link to comment Share on other sites More sharing options...
kevink1955 Posted November 30, 2018 Share Posted November 30, 2018 If it's anything like the other GM push rods it has either guide plates or a precision hole in the head as a pushrod guide. There should be a clean spot where it rubs the guide, that would be the top 2 Quote Link to comment Share on other sites More sharing options...

How long the copper will last is anyone's guess but they are probably really just worried about the assembly line The copper lasts long enough to set a matched wear pattern to each rocker arm point. GM suggests that you keep them in assembled order to the rocker and the lifter. Don't know many who do that, even GM techs. The hardened ball is supposed to save them both from damage/ excess wear of the push rod and rocker from miss adjusted valve lash. GM learned that with the first gen Olds and Caddy diesels.
