if one hole is low on compression and all the rest are fine wat do u think the cause would be?
if it was head gasket would they all be low on compression?

Could be still be the head gasket even if its only one one cylinder. Take the head off and investigate, you'll need to replace the head gasket anyway.
have you tried a wet compression test?

is it seriously down ? get someone to do a leakdown test will reveal any fooked rings, basically a few drops of oil down the bore would cause higher compression than before

take the header tank cap off and put your hand over the hole... if it tries to blow your hand off the top i'd say head gasket is fooked (engine running btw)
