Oil on spark plug electrodes

[red98]

Done it once.......fed some rope into the cylinder via the plug hole untill its full this holds the valve shut while you press down on the top of the valve spring, remove the collets and then release the presure on the spring.......this method does work but take extereme care......wouldn't want to do all  sixteen this way....if you on a really tight budget its doable.....me...new gasket every time and a great time to increase compression by regrinding the valve seats
