For running in a new cam and followers. About to build the engine back up but need advice on ‘running in’ pastes for the new cam and followers please. Also, been advised in the rebuild to cover everything in a high zinc oil then fill with the same oil for its first ‘burn’. Then drop the oil for what I would normally use. Break in for 500 miles with no overloading the revs. Then reset valve gaps and drive as normal. Any recommendations or advice, helpful. Thanks in advance.
