A recent post to this website regarding T.C.M. lifter problems contains a statement that I did not make. I did not state that we regularly send back well over a third of the lifters that we receive from T.C.M. This simply is not true. We haven’t returned any lifters unless a warranty claim has been submitted for consideration. I would also not suggest the disassembly of a unit without justification. Oil analysis and oil filter inspections are adequate, however, rust can be a problem. If you have any questions or comments please contact me at dallen@poplargroveairmotive.com
