What is the fixing used for these? The top one on mine looks like a stud in the tube, but there's only a few threads to get the nut on, so is this actually a stud or is it a screw that has been broken and bodged using a nut?
lets see yours rick... Actually you're talking about the top section!! The oil filler tube is bolted to the block, the stud on the tube only has a thin half nut on it, so that's why it looks wrong with a full nut!!
Got a cable tie on the bottom, but not the top, new bellows. There's still a leak around this area, but it's really hard to see if it's running down from the bellows or from the filler tube gasket. From the position, I guess the oil needs draining before taking off the filler pipe to check the gasket.
I used fuel line for years on the dip stick tube , but bought a bellows a couple of years ago and it's nearly goosed. Back to fuel hose with hermatite next time.
