So I now have a small horde (OK 32, but it certainly FEELS like a horde...) of roller lifters and pushrods from my salvage yard hunting today. They're obviously used but look to be in good shape, but are kind of dirty and got rained on solidly today.
What's the best way to clean them up and store them for when they actually get used? Carb cleaning dip? Brake cleaner?
Clean them up with pretty much any solvent you would normally use. Carb dip is great. Do you have a parts washer? Stick the nozzle down in the pushrod cup of each lifter and backflush them. Same goes for the pushrods. If you don't have a parts washer, a big bucket of soapy water works great too.
Blow everything off thoroughly with an air gun and coat with WD40, engine oil, PBblaster, anything that will coat it and keep it from rusting. I've stored crankshafts, cams, lifters, connecting rods, and blocks like that for years and never had an issue.
With metal preservatives, the thicker the better, cosmoline is the best. I have heard good things about brushing on STP oil treatment and wrapping in newspaper.
