Well, more progress to report on from the last couple of weekends. It's getting close now
The water pipes to the LPG evaporator were hooked up. I connected the incoming water feed to the tapping I created on the left hand cylinder head:
As I fitted an electric thermo fan to the car a long time ago, I used to have it controlled by a Davies Craig adjustable switch (see below), unfortunately the switch really isn't designed for water crossings, if it got wet either the fan would be stuck on, or wouldn't turn on at all!!:
I figured I needed to replace it with something that was a lot more durable. So I measured the threads of the existing sensors on the EFI manifold and discovered that the tempeature sender is M12 and the strange 35deg temperature switch was M14. I ended up finding a 95deg on and 90deg off temperature switch with an M14 thread. Turns out it is a part from the M30 BMW's.
Below is the original bosh 35deg switch and the replacement BMW 90-95deg switch:
The new switch fitted:
I bought a new clutch slave cylinder and fitted it, you can just see it in the bottom corner picture below:
I tried my best at bleeding the clutch by myself, but that wasn't successful... Wayne, if you are reading this, i'm going to need to borrow you next time you are in to do this
After packing the oil pump gears with vaseline, I primed the oil system with a two speed drill and a crushed piece of pipe to engage on to the oil pump drive. Below is the very sophisticated tool:
What I discovered when first turning the pump over with vaseline is how incredibly hard it was in the first few turns! It almost ripped the drill out of my hands. Anyway, within a few turns it eased up and was getting oil pressure. Basically, I was winding the pump over until pressure built up, then I turned the engine over by hand until the oil pressure dropped completely, then repeated the process untill I got oil up at the rocker shafts and all the hydraulic lifters filled up. Hopefully when it starts the lifters won't rattle.
The radiator was installed, coolant pipes and the distributor fitted:
The car used to have an issue where the throttle would stick partially open, which was a nightmare when 4wding and you would try to go down a hill as gently as possible to find the throttle sticking on you! I discovered the cause was that the disc of the throttle body was not centered correctly, on loosening the screws and shuffling the disc around, I found a position where it no longer stuck.
I moved on to temporarily energizing the LPG solenoids, I wasn't sure if any of them would have been stuck after sitting in the same position for a year. After energizing them I got gas out of the evaporator so that is all looking fine.
Intake air pipe fitted, throttle hooked on, oil put in to the gearbox and transfer case and this is where it is at now:
At this stage, all that is needed is for the ignition system to be hooked up and the engine is ready to start!!
I've spotted in the workshop some stainless steel ignition cable which I am toying with perhaps using to make up some new leads. As there is no EFI system on the car, there is no reason why solid core leads cant be used - Wayne, got anything planned for the stainless steel ignition cable?
That's it for now.
