I don't understand the logic of not using a washer on the sump plug. A sealing washer (either copper or nylon) is designed to accommodate imperfections in the mating surfaces - and it also makes removal easier. Any sump plug installed without a sealing washer will run into the problem of the plug becoming locked onto the sump. I've owned multiple hundreds of engines of all types, makes and applications, and never had a sump plug come undone yet - in 59 years of owning and operation of engines. The only instances I know where a sump plug came undone with engine vibration, was where the person who installed it, forgot to tighten it properly.

Well Skippy, running a petrol engine on diesel, or a diesel engine on petrol is certainly not going to make them "run happily", they are vastly different fuels for each engine, and serious damage results in each case. Diesel has a cetane rating, petrol has an octane rating, and the ratings are the polar opposites of each other. Octane rating is the fuels resistance to detonation, cetane rating is how easily diesel burns. When I said, "run happily", I meant within the context of the fuel type used in the correct engine. My brother ran short of diesel on our minesite once, and needed to go to Kalgoorlie in his Landcruiser (HJ60 diesel turbo). He found a drum of lighting kerosene, nearly filled the Landcruiser with it, and then mixed in about 10% engine lubricating oil. The Landcruiser ran like a dream on that mix, so he continued to use up all the lighting kero in the same manner, as we had no need of it any more anyway (the kero fridge we had blew up and caught fire, and burnt a cabin to the ground, but that's another story!)

The PLASTIC is called HDPE, High Density Polyethylene. It's a very durable polymer, UV resistant and fuel resistant. However, as with all PLASTICS, it doesn't last forever, and petroleum fuels contain many potent chemicals that are well-known as solvents. These solvent-type components of petrol will eventually migrate into the HDPE and make it brittle and more prone to cracking and leaks. However, it would take at least around three decades or more for the effects to become visible, by which time one would expect to be starting to look at replacing the HDPE tank. The article below is from 1996, when manufacturers were still tossing up the "pros and cons" of plastic fuel tanks. Since the early 2000's, the vast majority of cars produced have had plastic fuel tanks, and I can't recall too many downsides. At least internal corrosion is eliminated. Steel VS Plastic for automotive fuel tanks - https://www.tms.org/pubs/journals/jom/9607/alvarado-9607.html#:~:text=High-density polyethylene (HDPE),has been on the increase.

I've never claimed to be an expert on fuels, I merely summarise what I know, have used, and have read. Engines will run happily on a wide range of fuels, as evidenced by the old "petrol-kero" engines. When I say refining standards are vastly different between the U.S. and Australia, I'm talking about fuel standards specifications, additives allowed, and octane ratings determined. U.S. fuels vary more widely in constituents as compared to Australian fuels, and many chemical additives were added to U.S. fuels that would not be approved in Australia. For many decades, there were no controls whatsoever on what went into U.S. gasoline. Only diesel in the U.S. had a fuel standard, ASTM D975, introduced in 1931. Gasoline in the U.S. did not receive a specific ASTM fuel standard until 1988 (ASTM-D4814). The first attempts to regulate gasoline in the U.S. came with the Clean Air Act of 1970, and gasoline fuel conformity standards were not formulated until a Motor Fuels Task Force was appointed in 1984, which task force brought in set fuel standards, several years later. Basic Australian fuel standards were in place by the 1950's, and have been regularly updated since that time. But fuel grade wasn't included in those historical standards, and lower octane ratings than the U.S. were acceptable. The biggest change to Australian Fuel Standards came in 1986 with the elimination of lead in petrol - and the total revision of the Australian Fuel Standards in 2000 set the tone for improved fuel quality.

83% of our refined petrol and diesel comes from overseas. South Korea is our biggest supplier of refined fuels. I seem to recall Singapore is our biggest refined petrol supplier, and South Korea is our biggest refined diesel supplier. https://www.statista.com/statistics/674596/australia-petroleum-import-volume-by-country-of-origin/#:~:text=In 2024%2C South Korea was,12 thousand megaliters in imports.

As Turboplanner correctly states, fuel and refining standards are vastly different between the U.S. and Australia. As a general guide, Australia tends to follow European fuel standards more than anything. The Americans use "octane rating" for their bowser fuels. Their bowser "octane ratings" are 87, 89, and 93 octane. But U.S. "octane ratings" are calculated by averaging the RON (Research Octane Number) test result, and the MON (Motor Octane Number) test result. Some U.S. refiners even use another test called the AKI (Anti-Knock Index), and average the AKI and MON to get their octane rating. Australian petrol comes in 91, 95 and 98 "octane". These grades are measured by using the RON test, ONLY - the same as the Europeans. Australian fuel standards are dictated by the Australian "Fuel Quality Standards Act 2000" legislation - which standards are regularly updated to reflect improved fuels, and lowered levels of toxic compounds. The accent in recent years has been on reducing the levels of aromatics in petrol, as well as lead reduction (since 1986). The aromatics combined are referred to as BTEX - benzene, toluene, ethyl-benzene and xylene. These compounds are all regarded as toxic and carcinogenic. Benzene in particular is nasty stuff, it contaminates groundwater all too easily. Benzene always has been a natural major constituent of petrol/gasoline, but the Australian legislation is intent on making sure refiners keep the BTEX levels down to around 25%-28%. Methyl Tertiary Butyl Ether (MTBE) was added to petrol/gasoline for decades as an oxygenation compound, designed to ensure complete combustion of the fuel. It was started to be removed from fuels in the 1990's, and the U.S. legislated for its eventual removal from 2005, but it is still being used as an additive in some U.S. gasolines at modest percentages. In Australia, the level of MTBE in our petrol is only allowed to be a maximum of 1%.

Sacrilege!! He cut up a MERLIN engine, to make a V-twin for a drag bike!? He should be hung, drawn and quartered, and his remains fed to the wolves!! 😬

What did you think about the $328 fee for activating the landing lights!! Gee, have they got to crank up a 250Kva Cat genset to operate the lights??

Moneybox, it's quite likely the Cue Shire Council will set an annual lease fee for the hangar site, plus you'll be charged annual rates as a "land owner" in the Shire. Then, to erect a hangar, you'll be up for application fees, building permit fees, building services levy, and building licence administration fee. They get you coming and going. Below is the Council fees list, but the annual rates charges are not listed. There's a minimum annual rates charge for any property, usually $500-$600 on average. Then they'll want to know what other facilities you're going to install, and how they'll be serviced or operated. I see where Cue Airport is also an ASIC-card controlled airport. That's another unnecessary hassle. https://www.cue.wa.gov.au/documents/39/2023-2024-fees-and-charges EDIT - I just found the Cue airport information, as below. They also charge a fee of $9.70 per passenger, outgoing and incoming. Airport » Shire of Cue WWW.CUE.WA.GOV.AU

When I was gold mining in the Kalgoorlie region in the early 1970's, I was in the Kalgoorlie State Battery one day, when a prospector wheeled in a wheelbarrow full of specimen stone, mostly quartz. There was highly visible gold in every piece of stone you looked at. The stone was too rich to put through the stamps and over the table in the battery, so they just put it through the big Berdan pan, until it was well ground. I recall that he recovered something like 280 ozs of gold, from just that one wheelbarrow full! I got 600 ozs of gold out my small open pit mine at Higginsville, but it took 8 years of Norseman State Battery crushing, and the hauling of 13,000 tonnes of ore 60 kms to Norseman for treatment, to get it! The ore haulage was mostly done with a '68 Perkins-powered, tandem-drive "Butterbox" International ACCO, DF-1840 tipper! - an ex-council truck! The East-West truckies used to curse me, holding them up on the hills, while the old 120HP Perkins ground her way over them loaded, in 2nd or 3rd gear!! The Norseman State Battery manager, "Dick" Della (a top bloke) used to tell me stories of when he worked at the Lake Darlot State Battery as a young bloke - and there were 3 mines in the area that brought in their ore to be crushed, and Dick told me you could see visible gold in every shovelful he picked up. Those 3 mines regularly produced multiple ounces of gold, to the ton of ore. In those early days, there was no hopper at the stamper, the ore was dropped onto a big flat plate alongside the stamps, and the employees picked up the ore with shovels, and shovelled it straight into the stamper boxes!

I've worked in bitter cold and worked in Darwin heat, and I know what I prefer - give me the heat any day. But the humidity during the "buildup" in October can definitely send you "troppo". However the "big biteys" hiding in the water everywhere in the NT is a bit off-putting. Funny, they didn't bother too many people during WW2, plenty of photos of soldiers swimming in the NT during the War - might have been because they learnt quickly that getting anywhere near those humans saw plenty of .303 bullets coming their way. Used to be a regular sport for a long long time, going out "spotlighting" for crocs with a few .303's. Wasn't anywhere near the numbers, or the number of attacks, back then. We've let them run riot, they have no predators apart from humans.

I guess Dan could be rated as premium instructor, as regards avoiding crashing, because he's crashed so many aircraft himself! Maybe he should start educating aviation people about the foolhardiness of threatening to run over police with a DC-3? And I wonder if he's found the money to pay that US$1M defamation judgement? I think there's much better aviation instructors around, than Dan Gryder.

However, Turbo as always, deflected all the allegations and claims, and came out of the affair squeaky-clean (as always), claiming it was unfair to expect him to know about all the dubious associations and underworld friendships of many hundreds of employees way below his level of interaction, and he would certainly have never approved of the.........

Another ABC News article below contains a video of the crashed Drifter being lifted out of Fogg Dam by a helicopter and a photo of the wreckage, upright on a tilt-tray truck. The photo of the wreckage doesn't give fine detail, but it appears the prop is largely undamaged, leading one to infer that the engine wasn't delivering power when it impacted the dam. Tributes for pilot Mark Christie killed in ultralight plane crash near Darwin - ABC News WWW.ABC.NET.AU A 63-year-old pilot who died in an ultralight plane crash near Darwin has been remembered as "a great father" with a love of adventure and learning.

A couple who survived the crash have thanked rescuers, emergency services and the ATSB investigators - and have made a point of saying they almost certainly owe their escape from the sinking aircraft to the detailed instructions provide by the deceased pilot, on how to operate the emergency exit door. I would have to opine, their escape from the sinking wreckage was also due to the fact that they took the trouble to listen to the instructions carefully.

I reckon he's been "pushing the envelope" for possibly 20 years or more, and it caught up with him. That country is full of wildlife, especially big birds that can fly high. Hitting something like a magpie goose at the levels he's flying at in his videos, and you'd be history. The Fogg Dam birdlife is enormous. It's lucky they've got a surviving passenger who can probably tell the Police what actually happened. Experience the Wild - Where to Watch Birds, Fogg Dam WWW.EXPERIENCETHEWILD.COM.AU
