laweirich Posted July 25, 2006 Share Posted July 25, 2006 Hi I am new here. I want to take my hydraulic lifters out of my ea81 to inspect them. Can I take them out without pulling the the head? I goofed when trying to adjust them. I turned them in too far and now I can't get any play with the adjustment. Quote Link to comment Share on other sites More sharing options...
GLCraig Posted July 25, 2006 Share Posted July 25, 2006 It is possible to get them out without removing the head. I've seen it done a couple of times. My question is why were you adjusting them? You should not need to do any kind of valve adjustment to an EA81 with hydraulic lifters unless you have taken off the rocker arm assembly. Are you sure that you have hydraulic lifters? Most EA81s have solid lifters that do need to have the valves adjusted every once in a while. Quote Link to comment Share on other sites More sharing options...

That engine is supposed to be a hydraulic lifter engine. The reason I was trying to adjust them was on the 2 and 4 side it was making a terrific amount of noise.

Jerry DeMoss Posted July 25, 2006 Share Posted July 25, 2006 I don't think you need to adjust them at all.I would just run some sea foam in the oil before your next oil change.Should take care of it. Quote Link to comment Share on other sites More sharing options...
laweirich Posted July 26, 2006 Author Share Posted July 26, 2006 I Think I Screwed somthing up because now I can't get any play. What could have happened to the lifters? Quote Link to comment Share on other sites More sharing options...
GLCraig Posted July 26, 2006 Share Posted July 26, 2006 By chance did you follow the procedure to adjust the valve lash for solid lifter engines by mistake? The procedure for adjusting Hydro lifters is completely different. Quote Link to comment Share on other sites More sharing options...
laweirich Posted July 26, 2006 Author Share Posted July 26, 2006 The procedure for adjusting hydraulic lifters that was posted on here is to turn them in four turns and wait 15 minutes before you turn them back out. I didn't pay attention to what it said and I was thinking it said turn them in all the way until they stop turning which is what I did and now I can't get any lash.

GLCraig Posted July 26, 2006 Share Posted July 26, 2006 Did you remember to turn the adjuster 1-1/2 turns CCW beyond the point of where the valve closes? The method I've seen to pull them out is to take the rocker assembly out along with the pushrods and use a magnet on a telescoping handle to pull the lifter out. Then to put them back in, use a piece of welding rod that's just bearly small enough to fit into the oil hole in top of the lifter. You may need to jack the engine off of the cross member.

GeneralDisorder Posted July 27, 2006 Share Posted July 27, 2006 On the hydro engines, the lifters are meant to be removed with the oil pan off - the crankcase is cast differently to allow their removal if you loosen up the push rod adjuster and pull the rod out a bit. I think you can also fish them out as craig mentioned, but you risk dropping them into the oil pan anyway, and putting them back is a royal pain (again with the risk of dropping them into the pan). Best to just remove the pan, and replace it's gasket (OEM only) - you'll have an easier time, and getting the pan sealed up with a new gasket is always nice....

GeneralDisorder Posted May 28, 2017 Share Posted May 28, 2017 Search the forum. It's been posted (by me I'm pretty sure). Mind you, they are not supposed to require adjustment. GD Quote Link to comment Share on other sites More sharing options...
