[QUOTE="Roberto, post: 678784, member: 8160"] Hi Bro Maxion, Thank you for your reply thanks for taking the time. Water out of your tailpipe means a cracked head. A bad headgasket (HG) cannot cause water to come out, bad HGs cannot be that bad. HG issues are basically you losing coolant at least 1 mark per week, and when bad, white steam out the tailpipe and you losing coolant pretty fast..maybe 1 mark every 2 days or faster (all this assumes daily driving at least 20kms per day). Also, after letting the car sit overnight after a drive, if you pull out the spark plugs, you'll smell coolant in one or more chambers, and might even see coolant there. Wont be much, if you spin the engine (i.e. crank the engine) with the plugs out in the morning, you'll get very little if any coolant flying out the holes. However cracks in your cylinder head will cause water actual water to come out of your tailpipe. If you do the morning test as I describe above, you'll see alot more coolant in the chamber with the crack, seepage overnight will be high. Spinning the engine will cause this coolant to fly out and you'll know there's alot of fluid. Or you can even draw it out with a fishtank tube connected to a syringe. Did you change your cylinder head ? Or just the headgasket ? If you did not change your cylinder head, did you send your old head for a pressure test at a workshop to confirm there are no cracks ? Do you have good closeup pictures of your old hg ? If not, can you remember how it looked like, were there any tears, any breaks, etc ? [/QUOTE]
