I had a back and forth with the seller that asked, “you say you would not use the lifters, why? Are they rusty? Seller’s reply is,”..that they are not rusted, just a couple seemed like the plunger was tight and would not go down.” I am thinking to myself, I’ll disassemble each lifter and soak it in solvent.
At this point, I am still under the impression that they are “new” as advertised. Seller boasted that paper work was still with item. I don’t mind taking a chance on old, but new, lifters. I will not put used lifters into service. In fact, I believe the lifters in the box are not even the brand claimed, but old OEM put back in box when the Isky were taken out.
