....Welcome to R/C Universe tubetype1....[sm=thumbup.gif]

While it is clear that all the real mechanics agree that the the valves must be sealed 100%
to avoid problems later....it should be noted that real mechanics take the extra step necessary to
avoid any valve leakage, and the possibility of premature valve burning and failure, due to a
leaking valve. While it is rare....even an intake valve can burn if it should leak.

It seems like only the guys that are not really familiar with valve servicing would argue about
valve lapping....using only unfounded Internet arguements to serve their case, not actual experience.

This happens alot on the Internet....but it makes for interesting discussion.
