Hi all, yeah the cars ben running rough when idling the last couple of days, I checked the water levels in the radiator and it was fine. reservoir was empty tho, I started the engine with out the radiator cap on and there were tiny little bubbles coming to the surface, maybe 1 or 2mm in diameter. I have a feeling its the head cracked because I snapped the top off one of my bleeder bolts a while ago.

What do you guys reckon? I have a spare head in the Garage, am gonna send it off to get crack tested and mildly ported on the exhaust side.

will look into that tomorrow. The tiny air bubbles rising to the surface of the radiator is an indication of a leak in the cooling system? What damage will I do to the car if I drive it for another week on very short journeys not letting it get too hot?

Can they be fixed before it becomes bad...There is a proper device thats will screw into the radiator cap hole like a radiator cap, that does the job of bleeding.

Once the head cracks they're still pretty drivable, i drove for months with a cracked head and my mate another 5 months on me. We both needed new radiators.

If you gonnna drive it, drive it like a grandma; probably advise not to unless it's the only way, and if it is the head, either get a confident mechanic to do it, unless u are confident yourself...cuz you here about ppl doing it themselves but cracking a year later neway...mine is running pretty good on coolant, probably used up a 2 full reseviour total over 8 months, and that's with two snapped bleeder bolts. And driving pretty hard.
