Reply to "MME ENGINE FAILURE UPDATE"

Doug - Let explain why the retainer mismatch matters. It was not a mismacth simply of material.

The tool steel retainer was wrong based on FIT, not just material. The retainer found on the spring did not fit snugly inside the diameter of the spring set. This then permits the spring and valve a greater a range of movement contributing to the lack of control exhibited in the valve train.

When checked with Manley it turns out that the only Manley part that fits that spring set correctly is a titanium retainer.

So again this demonstrates another instance where parts selected were not the correct ones.

None of the valve train parts inclusive of the cam were chosen or specified by me. I left it up to the engine builder.
