What happened to your floorboard getting wet? A compression test won't tell you anything about the cooling system unless your head gasket is leaking (or you have major damage to components such as cracked head, block, etc.). I doubt you have any of this, as I'd think you would definitely notice after flogging the car on the expressway.
What exactly are you talking about when you talk about seeing bubbling? Like removing the radiator cap and checking for bubbles? If so, that's not going to tell you much since the system will produce small bubbles as a result of normal operation. Now, if you are referring to coolant boiling, that's different. Like we told you before, boiling coolant is typically caused by a leak in the system. The only way to correct this is to fix the leak.
Either the system leaks, or it doesn't. You can check this 2 ways: With a cooling system pressure tester, or by running the car and looking for coolant shitting out of the system somewhere. Anything else is a waste of time until you determine whether there is a leak or not. Once you determine if there is a leak, then do a compression test or whatever you need to in order to try and pinpoint the leak. If you troubleshoot in a logical sequence and understand why you are doing tests (and when to do them), it will save you a lot of time and decrease the chances of incorrect diagnoses.
