Is all I can think of at the moment! Quote Link to comment https://www.bigmacktrucks.com/topic/76341-e-tech-300-eup/#findComment-589591 Share on other sites More sharing options...

Joey Mack Posted Wednesday at 06:35 PM Share Posted Wednesday at 06:35 PM Yes sir, i am thinking the guide pin is jamming the lifter in the bore, and may need to be drilled out with an 1/8" left hand drill bit to use an easy out to rotate and pull the guide pin 1 Quote Link to comment https://www.bigmacktrucks.com/topic/76341-e-tech-300-eup/#findComment-589595 Share on other sites More sharing options...

TurdFerguson Posted 10 hours ago Author Share Posted 10 hours ago It is on cylinder 2. Trying to drill out now. The lifter is wedged up, not down. Doesn't seem to have contacted the cam.

TurdFerguson Posted 4 hours ago Author Share Posted 4 hours ago Cam was trash. Pulled the Cam out, then beat the plunger down through with a hammer and punch. Lifters are shot, too. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/76341-e-tech-300-eup/#findComment-589660 Share on other sites More sharing options...

Joey Mack Posted 5 minutes ago Share Posted 5 minutes ago Hopefully his shop has vast knowledge on E-Techs.... honestly, if there not a crack on the outside of the block at the bore area, i bet its fine. I beleive the cam pushed it up out of the way, and it got jammed by the guide pin and the the hammering stopped. The EUP spring was not strong enough to push it down for more hammering..
