We also state that K-Seal is not suitable for coolant to oil or oil to coolant leaks and so any attempt to solve this would be the best efforts only endeavour. **Q: My volkswagen 1.9 tdi transporter is leaking exhaust gasses into the cooling system and thus over pressuring the system, will this product cure issue?** A: If the crack in the head thats causing the problems is absolutely tiny then it may fix your problem but if it's larger than a millimetre or something like that which it states on the bottle somewhere then no it wont fix the problen and unfortunately you'll have to get another head either main Stelar or eBay or something like that... **Q: I have oil leaking from the engine (v old citroen saxo). will this fix it? is it the right product?** A: No it will not stop an oil leak. It is designed to go in the coolant system and stop head gasket leaks emitting from the coolant system. If you have oil leaking from the engine at the head gasket you need the cylinder head skimming and the block re-building. If you have oil leaking for elsewhere on the engine, that will need taking apart and rebuilding with new gaskets. **Q: Have a bmw x5 4.8is v8 petrol. am losing water but only a tiny bit - have used one of these 2 weeks ago not cured - do i need 2 given engine size?** A: Hi, no there is no need to use another bottle as K-Seal is calculated by coolant capacity and not engine CC capacity. It is more likely that the leak is so small that the particles are not being drawn out of the cooling system. This is just a case of waiting a little longer for this to happen but I recommend that the engine is run for 15 - 20 mins each day if the car is not used on a regular basis.
