On my way to work I found the garage floor was covered in petrol. The tank had leaked.
I mopped it up and checked for drips and went off to work.
When I got back another gallon or so was on the floor.
The leak was coming from the outlet pipe area. I drained the tank properly and remade the tank connection. Easier said than done.
I had to make the first part in 6mm pipe then upsize to 8mm. This was because the nut for 6mm pipe was too short and was fully in before the pipe was clamped tight. The nut for 8mm pipe was a lot longer, so the 8mm pipe was bored to accept a bit of 6mm soldered into it. The 6mm olive would then seat inside the tank and make a good connection.
That was the plan and it seems to have worked so far.

Engine running problem solved.
I discussed my engine problems with the chaps at work. One contacted his brother in law who suggested it was a leak between the carburettors and the inlet port.
I had a look at all the connections and they looked fine and tight. So it could be the vacuum advance or the engine breather. A finger over the vacuum advance port had no effect so the breather was removed and a 3/8” socket extension stuffed in the hole.
Eureka – the engine runs at a constant speed - very fast but the idle speed was adjusted quickly and Jemima was left to idle and warm up for the first time in 20 years.
The garage filled with smoke from the oil that was burning of the outside of the engine, the exhaust was emitting less smoke now. Actually I’m using leadfree with a slight diesel contamination due to a mistake at the pumps several months ago so a bit of smoke is expected.
The BMW thermostat finally switched on at 99˚C but it was connected to the slow side of the fan so it didn’t have a great effect at first. The lower temp switch doesn’t seem to be working. I switched Jemima off and allowed her to cool down.
Next day I came back to start her up again and all I got was a click from the solenoid again. Out with the starter motor and a recrimp of the stud-winding connection got her restarted again. I’ll change the motor next time.

Underneath stuff
This week Jemima is back on axle stands.
The plan was to fit the exhaust, clutch slave cylinder and new rear bumper.
None of which was easy.
Couldn’t find a bolt that would fit the slave cylinder mount. Then realised they are 3/8" UNC, not UNF, so bought some new ones from Namerick. When I got back, the next bolt out of my used nut/bolt box was 3/8" UNC.
Couldn’t find the bumper support bars anywhere, they were only painted last month, so started on the exhaust.
The manifold mount fitted easily enough but none of the others did. Drilled a new hole in the boot floor for the rear mounting. Then found the bumper support bars and realised they would be in the way of the exhaust.
The rear bumper irons and triangular reinforcing bracket use four bolt holes each. Three in the boot floor and one in rear lower panel. None of which really lined up. Boot and rear panels are "new" and came with holes pre drilled but not quite in the right place.
Six more holes were drilled in the boot floor to fit all these bumper supports. Then the bumper itself was not very central so more holes where drilled in the spring bars to sort that out.
I liked the look without the overiders fitted but "she - who must be obeyed" wanted the overiders. Naturally the original ones would look silly so new ones were ordered.
Drilled new holes for some M6 Rivnuts in the rear bulkhead for the centre exhaust mounting and reversed the rear mount to still use the hole drilled previously.
So, three 5 minute jobs, which took about a week.

Hydraulics, and Instruments
Today it was time to fit the brake pipes and hoses. Copper pipes were fitted 22 years ago and, as expected, they are still in perfect condition.
I also fitted Goodridge braided hoses. These were bought, but not fitted, 15 years ago! Fortunately they claim to be guaranteed forever. We'll see if they last that long.
Whilst crawling around under the car to fit the rear pipes and hoses, I found it rather difficult to get back up again, wedged as I was between car and garage wall. Maybe I need to fit some some of those handles that usually adorn old folk's bathrooms.
It being rather chilly outside, I also cleaned up the Speedo and Tacho, ready to fit to the dashboard. The dashboard was painted many years ago using the original looking crackle finish paint. It took 3 goes to get any crackles in the paint. It needed to be done in the right temperature environment. "She" wouldn't let me do it in the house so I took it to work. The results were superb.
Decided it would be nice to see the Dashboard fitted today, so began the task. Then found it wouldn't fit due to the door seals (see earlier post) and the windscreen bolts had bowed the dash top, such that the centre section wouldn't bolt in place. This explains why the windscreen centre bolts had two gasket/spacers fitted in the dash top. Both are now fitted and the dashboard looks fine - except the door seals are hanging off again.
