rnettleship Posted October 29, 2013 Share Posted October 29, 2013 I have noticed over the last few months that the rocker/lifter noise has been getting louder and now it sounds like I have at least one lifter that won't pump up. I understand that the top ends of these motors were not the best and some ticking is to be expected even though they have hydraulic lifters.I pulled the valve cover and intake manifold over the weekend and saw 3 completely dry rockers and the related push rods were ground to a point. On the positive side, the cam looks good and it is getting plenty of oil. I noticed that all of the rocker arms have wear on the valve side as well. (recess ground into the rocker where it presses down on the valve)I can replace the pushrods and lifters easy enough but rocker arms seem to be scarce. I really need to keep the costs under control as well so I'm looking for some advice. Does anyone make adjustable pushrods to fit these motors so I have some ability to make up for the wear on the rockers? Are there any shims that can be used on the rockers to accomplish the same?I know the right thing to do would be to replace everything but I just can't shell out $700+. Fusicks only has replacement rockers for 52'-58' which I think will fit my 50' but I would need to replace all 16. Replacement push rods, lifters and gaskets will be around $300. I'm ok with a little ticking and I believe ensuring that all of the rocker oil passages are clear and damaged pushrods are replaced should put me in a good place but I really don't want to do this job again either.Any "tricks of trade" out there I should be considering?
