Q:Currently in and around Melbourne we have water restrictions - largely voluntary. Filling engine cooling tanks while not banned is a bit of a waste. My Southern Cross P has a 110 litre tank on it. The water in the top is usually hot enough to steam, but the water in the bottom never gets hot. I'm considering putting a much smaller 40 litre tank on it. The engine uses an endothermic cooling system - ie. not pumped - the water syphons when it gets hot enough. I know that the top pipe will have to be level with or slightly above the head inlet pipe so that water will always cover the combustion space. Usually I have the lower pipe lower than the engine outlet - this is the bit that I'm not sure matters. To use the smaller tank I have to build up its height so its top pipe matches the engine top pipe. This means that the water from the bottom outlet will have to flow horizontally rather than downwards - will this matter? I think probably not as the system depends on heat not gravity but I do not want to find out the hard way. Anyone got any thoughts on this? As I have a show next week, I'm an impatient bugger and need an answer today Paul…

After a general discussion on the wonders of mollasis / mollases (liquid sugar) as a derusting agent, specific comments and questions began to come up. This faq does not include the initial "wow it works" but does include the subsequent messages.

Many of us have horizontal stationary engines with an external drip oiler which drips oil at a regulated rate onto the piston (usually through a tube right down into the cylinder). The oil serves two purposes, it keeps the piston and rings lubricated so they can move freely and enough oil falls through a hole in the piston barrel to lubricate the wrist pin and crank journal.

The big questions are what kind of oil, and how much oil?…

One common topic which appears from time to time on the Stationary Engine List is should we drain our fuel tanks before storing an engine? Personally, if I'm not going to use an engine for a few months I usually drain the fuel tank and leave the cap loose so it stays dry and condensation has a chance to escape. I drain the tank to reduce fire danger, I really have no other reason. Todays fuel seems to be chemically very stable and can last for years. I live in a town on the fringe of the bush in a high fire danger area and I try to be aware of prevention. As usual the list had varied opinions, read them and decide for yourself!…
