I did a radiator drain and fill, oil change, and lower control arm on my 93 civic hatch today. It has an LS/Vtec b18b1 block and GSR head with OEM honda head gasket (12251-P30-014). Entire parts list can be found in my build thread in sig. Broke it in, has roughly 1500 miles on it now. Never overheats, no smoke from exhaust, no oil contamination.

I was letting the thermostat open up when the radiator spitting out coolant like there was exhaust pressure pushing it out, however it didn't do that while the engine was still warming up. It seems to be a little excessive, I'm used to just a few bubbles popping and the level going down a bit. Am I being paranoid, or does this look like a head gasket issue?

Also should note I have solid motor mounts, could it maybe just be vibration?

What oem head gasket?
plug in head to block off oil port?

Buy one of those to monitor bubbling and not create big mess.

Tested the cooling system at work, no exhaust gas present. Held down the radiator and it stopped. Basically the solid mounts causing vibration. Haha, who woulda thunk it!

What coolant you running? looks horrible, thought that's what your concern was lol

It's actually two brands, I'm going to buy OEM stuff and do a complete flush soon, gotta grab that, a honda OEM radiator cap, and get some honda MTF for my trans. The reason it looks like crap is its a red and a green that's mixing. I broke the motor in with the red, and did a drain and fill with the green. They're both the same type though, no gel for me haha.

The lisle funnel sirtef9 showed will help, bubbling is normal, it is just air being relieved by the system.
