Good news m8, I'll get that sent off to you early this week hopefully.

Cheers dude, that'd be much appriciated When I said I'd have it for a rainy day... that's a bit soon!

Progress has been slow... but I've been making sure I get all my alignment right before I make a load of stuff.

So... to ease fabrication of rear mounts, I made a car today. Lidl welder at the ready...

Measure, scribe, measure, divide, centre punch, drill. Then hacksaw, scribe, measure, do maths, do more maths, then more maths, drill, metal glue.

I give you... one car.

Close up of metal glue

Bolt up a stock rear mount



And then the old mount slides on. Proof therefore, that it is a perfect 340 rep.



Now I have a spare 340, I can build each type of my new rear mount design onto it. It might not look much, but its taken ages to fit engine, measure with the laser thing, move things a bit, try and measure the deflection on the mounts, move it more, re measure etc etc etc.

In theory... unless I've cocked something up, this jig should align the tailshaft from the bellhousing at the exact position in all 6 degrees of freedom relative to the main crossmember.

I hope.

Hi Chris.
Spot on mate. Its going to take someone like yourself to keep our cars running in a few years time
because its getting harder all the time to find stuff. Well done.
Cheers Mark.

Thanks guys

Engine ran for the first time since I explodinated things at 10pm last night.

Ran for the first time on 4 cylinders at around 11:30 last night. Test drive showed up minor problems but I wanted to make the BKV today. So, over the next week or so the prop is coming back off, maybe engine back out.

I *will* have a reliable 180-200bhp off of this set up eventually. And daily it.

Pics of engine mounts when I pull them out later in the week, those at the BKV will confirm how well it's now mounted.

From the other thread

Pics or gtfo

I even washed it dude. No pics from BKV, twas very wet, Pete or Steve might have got some.

Holy Moley.

I've got a couple of photos but photobucket's upload won't work at the moment

We passed 19,000 miles in the 360 today

Can't possibly let it ever get to 20,000 I'll have to disconnect the speedo (whoops, did I say that out loud )

Will post photos on a new thread soon.

Good to see so many from here at the show despite the weather.

Any news on the photo's Andy?

Well... the last fortnight has been somewhat interesting. Firstly, fixing the drivetrain vibration. I've again no pics but will grab some when things are less hectic. Turns out that when I exploded the bellhousing I also bent the propshaft, 1.6mm of runout on it. No wonder I could feel it

So, off to Speedy's 'rents house to snadger a new one (that I bought for him... after snadgering his one before that too I owe Speedy one more prop)

So, all fine, starter has been making a funny noise though. Until Sunday, where I had a starter solenoid ticking, but absolutely nothing more. Bugger. New starter then. So, start changing it and housemate notices that I've got a fair amount of loom burnt and wires trying to escape from loom tape. Humph.

Had a bit more of a play last night, and sussed out what has caused this. The loom was melted open between the alternator and the headlamp/indicator/front lamp wiper. Stripping off the loom tape shows no more meltage apart from this.

The reason housmate spotted it was I was half way through changing the starter after it failed on Sunday so something wasn't ringing true. So, with the loom out, I thought I'd have another play with the starter. As per Sunday, it sat ticking the solenoid at about 100Hz, then, unlike Sunday, after 5 secs, kicked the motor. Ok... not a solenoid failure I've seen, but fine. Something has been sounding sticky in the motor since it went back on the road.

So, tried it again. Same thing, apart from the ticking before the kick started slowing down, as though the battery was getting flat. Bah, bugger. Tried it again anyway and just got a slow ticking from the starter. Arse. But I have a spare, so it's ok. As the loom is melted by the headlamps, that must mean the lamps arn't grounding properly, so I go to clean the earth for those too.

The body earth isn't that secure on the chassis. Hmmmm, ok, that would cause problems, as I have a 2 piece earth strap from the block joined at that point (uprated from the orig one which garages lean to hard on the lead battery plug with). Reached down to pull the wires off the starter and noted something bloody hot. Was the earth strap *on* the block. Which also reminded me of another post on a different forum yesterday.

Turns out that a load of block paint had melted off the block and onto the back of the strap, as the connection flowed more currents, it generated more heat, flowing less currents, generating more heat, etcetc. Cleaned up the terminals all the way along, mounted a new bolt on the chassis attachment point and see *no* voltage drop from battery earth to starter earth. Have another go on the starting handle (piece of wire from solenoid to the battery) and the motor spins first time every time, no noise, no dead battery as thought. Just sexy sounding starter motor.

I reckon the block earth went, and both the starter and alternator have been earthing via the alternators tiny ground stud that goes to the loom and then to the headlamps. Explains the dodgy headlamp issues, plus why I blew up an alternator last year, plus why only that bit of wire is screwed. 300amps of starter motor current down 21amp wire, nice.

Nice diagnostics man

[Chris_C]

3m of wire replaced, loom saved. Another 4 hours on the damn thing tonight, light evenings ftw.

Tomorrow will play fix the fuse box and all electrics should be good again.

Aaaand, driving again. I'd forgotten how good that engine is when it's running properly! Not driven it working for 7 months!

Get in. Awesome news.
You'll miss that Corset.
