This is my first post as I have only just got my hands on a Brumby. I was given it after the following happened and the body and rest is i excellant condition so to good to say no to. The engine in my Brumby has thick oil/water mix coming out the carbi, it is also in the oil, rocker covers, when it happened there was a lot of smoke from the exhaust, but the engine didn't overheat as there was still half a rad fill of coolant when the car was stopped, I think the air filter filled up and stopped the engine. The spark plugs are all the same and don't show signs of water. I have a few questions and would love some feedback/help. 1 What do I look for? Or what tests can I do to find the cause? I was told it may only be a welsh plug in one of the heads or a blown head gasket. 2 I would like to keep it original with the EA81 engine as I am told they are very strong and reliable. What mod can I do to the EA81 engine to get more power? There is so much emission control gear connected to the carbi there must be something in removing all that? Any suggestions to improve. 3 If it is worthwhile and "easy" is there another engine that will bolt up to the original gearbox and transfer box as its a duel range. Thanks, now I only have to work out how to post this...

From your description of whats going on, coolant is getting into the crankcase from a dead head gasket or welch plug (not Welsh plug as the engine isnt from Wales ) it is then being mixed with the oil and pumped out of the rocker covers into the aircleaner.

it is time to strip the engine down get the heads pressure tested and faced and then put a gasket kit through the engine.

sometimes a simple tst is just water, some pressure, remove sump plug and whatever buttermilk is in there and see if more of your new water added to radiator comes out through sump plug. Mods depend on your budget

The Welch plug was named after their inventors - the Welch brothers

Yeah Rachel's brothers
