Hi all,
Calling the knowledgeable folk of this forum. This is not strictly an A2-related question but it relates to internal combustion engines in general.
Is it possible to have a head gasket issue, i.e., pressure build-up in the coolant without any other of the usual symptoms? I get coolant out of the vent hole. I also have a minor leak from the thermostat housing but I am guessing that this is due to the o-ring that I haven't been able to replace when I took it out. The cap is brand new too. So am I right thinking that this might actually be a damaged head gasket and I am in a Trigger's broom situation trying to fix issues that are ultimately attributed to a higher-than-usual coolant pressure?
Fuel economy is a constant 46-47 MPG and performance is great. No white smoke, emulsification or changes in the level or colour of the oil/coolant. Compression tests are consistent with maybe some blow-by.
Regards,
Evros
