There a hole under each exhaust pipe on my engine (02). It seems to leak e some oil when I drive, its probably the sylinderhead gasket. Do anyone know anything about this. What is the hole for???:head meets wall:

I performed a compression test on my busa and found one cylinder with low compression. I poured a capfull of oil into that cylinder and did the test again to see what the results would be but noticed the oil dripping onto the garage floor. There is a small "weep hole" of some sort located just under the exhaust ports on the cylinder head. This is wear the oil was coming out of so I am 100% sure the air in the combustion chamber also is leaking out here causing a drop in compression. Does anyone know what the purpose of those holes are what type of repairs will be necessary? PLEASE HELP ASAP I AM ALSO ATTEMPTING TO REMOVE THE HEAD MYSELF. ANYHELP ON REMOVING THE CAMS WILL BE GREAT THANKS

After pulling the head I was able to get a better idea of which direction the hole was going and found that it is actually a "weep hole" located in the spark plug hole. I am assuming that this is for any moisture that may accumulate or accidentally get spilled into the spark plug hole and will allow it escape outside of the cylinder head. Note that this will only prove useful if the spark plug is still installed. If the plug is removed, any liquids spilled will go directly into the combustion chamber.

The holes are doing there job and preventing the spark plug holes from getting buried in oil. It's either the valve cover gasket or the round gaskets around the spark plug holes in the valve cover.
