My 2011 i30 hatch developed a mis-fire last weekend; dealer in town says the head is porous and this has let the coolant leak into the spark plug; says only option is to replace the head, plus the associated work, approx. cost of $5200.00
Geeez mate if that works OP is going to owe you a slab for sure.

Hope you're wrong..@Bx Tiger fan Can we have an update soon and maybe some feedback on the enthusiastic help offered please. Our helpful volunteer technical advisors may have saved you thousands!
@tw2005.My apologies Gerard, meant to put you are also due for a slab from OP as well.
The coolant leak bottle wont help as if it was used on a faulty radiator. This is due to the air-pressure normally is lower on the outside when its a radiator-leak. When a leak is in conjunction with the cylinders/head the enormous pressure from compression/ignitionstroke will the push it away from the crack. Sorry, no easy/cheap way on this one :-(

Sorry, no easy/cheap way on this one :-(Sorry you are talking utter bullshit. All internal areas of the motor /coolant system work above atmospheric pressure. Unlike you, I have used it, and understand its advantages and its possible limitations. We have here (per description) a small crack or area of erosion in the head. It is a coolant system failure nothing to do with "compression/ignition stroke". In this case, it is my first choice of a remedy.

So the one screaming loudest & talks down on other members are the guy whos right?
@ChipMIK sorry if you took offence to my direct comment. Unfortunately, your equally strenuous rejection of the stop leak solution came at a time when, once again, we were not getting feed back from the member who had made the original enquiry. Gerard (tw) and I spend a lot of time trying to decipher member's vague fault descriptions. We are getting quite frustrated with the self interest of the many momentary members who make use of the site and make this a thankless task. The solutions we provide should always carry this caveat : 'we cant see or hear the fault, cannot work on the car and this is our assumption based upon logic and/or our past experience'. If we haven't had experience in an area, we say so and try to point the member toward a more appropriate advisor.ChipMIK the vague fault description along with the mechanic's diagnosis of a "porous head" leads me to believe that coolant is leaking into the cavity/recess for a spark plug. The mechanic's comment indicates that he could see the leak, otherwise he would have mentioned possible head gasket failure.The spark plug recess is at atmospheric pressure. Ignition pressure has no influence upon the coolant system unless the head gasket fails or the head warps or cracks. In such a case, the evidence will be wide spread.
