ihscout54 Posted March 8, 2015 Share Posted March 8, 2015 Im sealing up a "low mile" motor ive had sitting for a few years. Its very clean. I now realize its so clean because its been tampered with. The rocker arms are swapped LH an RH. They are on the wrong sides. I also noticed one of them is missing the spring washers. It looks as tho it really doesnt matter which side the rocker arm assembly is bolted. Is there a difference? Ive never mixed them up befor. Also its been ran without the spring washers, is this really a big deal? I do have another rocker arm assy if needed but I dont want to waiste any more time here if I dont have too. This engine seems to have some crank shaft thrust play as well (crank moves a bit from front to back of engine). Ive seen this befor and im not too concerned about it but wondering what the experts say? Link to comment Share on other sites More sharing options...
Crazyeights Posted March 8, 2015 Share Posted March 8, 2015 (edited) I have seen them installed both ways many times. I am sure it isn't correct but it does seem to work. Perhaps someone knows the exact difference? Crankshaft end-play is common on the older engines that were used with a manual transmission due to the repeated pressure from using the clutch.

ihscout54 Posted March 9, 2015 Author Share Posted March 9, 2015 It would have been less confusing to lable front instead of left/right. Its a mistake ide not have made but ITs an easy one to make. There is a defference in assembly on the rocker arms front to back, the alignment could only be off slightly if at all. I wonder if it throws of the pushrods or maybe had more to do with oiling? Theres a reason they labeled them im sure. Im probably gunna pull them replace the missing spring washers and reassemble them on the correct sides. I think the head gasket will survive the 2 bolts being out for 20 mins. Link to comment Share on other sites More sharing options...
Crazyeights Posted March 9, 2015 Share Posted March 9, 2015 I have some extra parts for these if you need some rocker arm bits Link to comment Share on other sites More sharing options...
ihscout54 Posted March 9, 2015 Author Share Posted March 9, 2015 Kinda funny, as im looking in the manual for the head bolt torque spec i see the diagram for for the rocker assembly. Of corse it was different than what I had just done. Just starting to think man im losing it, then i noticed that it was for the ea71. So to further add confusion the ea71 and ea81 share a diagram and they are not the same. Link to comment Share on other sites More sharing options...
