Did you know......that you can actually partially strip hydraulic lifters and clean them? At least on 10 valvers anyway.
If you turn them upside down theres a protruding valve that contacts the valve stem.
If you carefully grip this with pliers and lightly twist it as you pull, that valve will come out so you can soak it in paraffin overnight to remove the deposits.
This has been a public service announcement on behalf of the Audi Party.
