The valve lash increased so to find out why I removed the cylinder head to
Inspect. The combustion chamber is pressurized and find that the valve To seat seal is now at 88%. The valve and seat are lapped to restore seal. The valve spring is removed and placed in a Rimac spring tester to test the Tension at installed height and at full lift. So the valve spring had lost Tension and had collapsed. If left un-checked, coupled with the funky Timing of the 163/86b with both valves opened at the same time, Jake Made mention of the possibility for the valve heads coming into Contact with each other. My version of the LE200 has the old syle Standard dual springs. The new springs in the latest verision of the LE200 uses the bee hive springs which keep better control of the valve And eliminate spring harmonics. The new LE200 heads also have Larger 46mm intake valves, don’t recall what the exhaust valve size is. |
