Ha try and figure this one out!
So i am losing coolant somehow, yet i dont have a leak. The car runs like **** and wont stay in tune for nothing. I think i have a blown head gasket.
I drain the oil. All looks good.
I do a comression test and it reads starting from left to right 232 235 220 235
(keep in mind plugs 1 and 3 were wet)
I do a leak down test and precentage lost is 9 6 9 4
So i figure it isnt the head gasket.
well i drive it, come home, and do another leak down test with the motor hot.
i unplug the injectors and put the tester in hole #1 crank 4 times and then steam starts shooting out #3. i take the tester off one and it starts steaming too. and you can hear drips hitting #1 and then sizzling.
If the tests came out fine then how is fluid getting in my cylinders?

Sounds like you have a headgasket leak in #3. The HG leak might be very minor which is causing you to consume coolant. It's not showing up on compression test b/c the coolant in the engine is making up for the leak. When you crank the engine for the compression test, the coolant in the engine is resisting compression and giving you a false reading.
Try draining the block of coolant and then trying the comp test once again. (remove the coolant plug on the front of the engine) Let the pressure sit for a short while and see how much it drops. Your engine should be able to hold pressure for sometime.
