The little Moke only leaves a few light drops of oil on the garage floor which is quite surprising for a British vehicle. I've previously spent a bit of time trying to track down the source of the leak and I'm almost certain that its coming from the rod change on the gearbox. So I included a rod change anti leak seal kit in the latest order from Minisport.

The kit consists of a small factory seal as well as a dust boot for the rod. Included in the kit is a machined aluminium donut that is fitted with an outer O ring. This part is non standard but reports are that it reduces the sideways force exerted on the seal in the hopes that the seal will last longer. Another option is to double up on the factory seals, but the little kit was only a few dollars more than the cost of two seals, so I figured what the hell, let's give the kit a go.

In order to fit the new seal the whole change mechanism needs to come out so that was the first order of business.

Since fitting the larger diameter exhaust I've noticed the occasional knock coming from underneath so I suspected that either the exhaust was making contact with the gear selector mechanism or that the gear selector mechanism was making contact with the body.

Turns out it was both, but the worst one was the gear selector making contact with the side of the floor as witnessed when I pulled off the gearstick gaitor.

My fault entirely as when I fabricated the new rear selector mount as part of the exhaust install I had to shift the selector sideways to clear the fatter exhaust. So I need to deal with this while I have the selector mechanism removed.

While I was waiting for the oil to drain I quickly pulled out the selector and cleaned up around the old seal.

In the box of parts that came with the Moke was a short shift kit that the previous owner had already fitted to a spare housing, so I figured while I had the mechanism out I'd give the short shifter a go.

I made quick work of changing over the custom rear mount, rod connector and reverse light switch from the original mechanism to the short shifter and by that time the oil had drained, so I was able to dig out the old seal. Came out easier than I was expecting.

Then tapped in the little aluminium donut followed by the new rubber seal. Luckily I had a deep socket that was perfect for the job. With that done I turned my attention to opening up the gearshift hole.

It was a bit tricky as I needed to retain the 4 holes for the mounting screws as well as leaving enough meat so that the gaiter would cover my butchery, but I took out as much as I could with my dremel and then tidied the area up with a spritz from a colour matched rattle can that I also found in the box of Moke bits. It's not a perfect match but I'm not too fussed as it is all covered up by the gaiter anyway.

Popped in the short shift mechanism and refilled the oil and it was time for a test drive.

In summary there is something desperately wrong with the short shifter. First gear selects easily. Reverse is a bit hit and miss and 2nd, 3rd and 4th are a complete no go.

I suspect that old mate has assembled something incorrectly inside the mechanism but by that stage I was running out of time, so just reinstated the original mechanism for now.

I'll do some homework on the short shifter when I'm less time poor and hopefully I can get it sorted.

Our Moke has always suffered with an interesting starting problem. Start it every day and she starts almost on the first turn of the key, but leave it for say three days and you need to crank it over for a good while before it will run. This issue wasn't helped by a dodgy operating choke mechanism, but I was able to sort that out many moons ago. However the excessive cranking is still a thing. It's bloody irritating so earlier this week I decided it was time to investigate.

The Moke had been sitting for about a week since it's last start so without attempting to start it my first step was to pop the lid off the fuel bowl.

Bloody dry as a bone !

My next step was to open up the storage unit in front of the fuel tank to check the status of the inline fuel filter that lives in there.

Filter is full of fuel but does look a bit crusty inside so could do with replacing.

Next step was to pop the hose off the outlet on the mechanical fuel pump and see what was cooking there.

Hose end was dry.

Chucked the hose end in a clear bottle and got Mrs Flash to crank the engine over while I watched the bottle.

While she was cranking I did the old "1001, 1002, 1003 .... count" and sure enough it took just under 10 seconds of cranking before fuel started to spurt out of the pipe.

Okay, so to my simple way of thinking this indicates that the fuel pump was completely dry and it took that long to suck up the fuel from the filter/tank.

The million dollar question is why is it so?

I'm thinking it can't be fuel evaporation due to heat soak because this would happen even after a few hours of standing, not just after 2 or 3 days.

It could be some kind of air leak on the fuel line that is breaking the vacuum and allowing the fuel to run back down the fuel line, but since the fuel inlet is at the top of the fuel bowl on the SU carby I can't understand how the carby is being "sucked dry". Unless the breather hose on the tank is blocked and is causing such a massive vacuum in the tank that sucks the fuel out of the carby and pump. Could this be the case ?
