Hi, i know it's one of the questions - how long is peace of string. Got 55reg C4 1.4 petrol (49k miles on the clock). Head gasket is failing, its leaking water quite badly now (oild is fine, engine is not smoking). It's result of overheating about a year ago. Now I have dilema on either to try to repair it or just scrap it. Has put too much money so far (new water pump, new alternator, now O2 sensor in 18 months alone + wheels need balancing, door has been bent, bumber scratched, 3rd brake light's gone-broken wiring). Any ideas what are estimate costs of that kinda job? Thank you.
