As I said about 20 years ago!
I was fairly sure it was black……but mind played tricks.

When that wire came disconnected my car would start but not run.

Around 8:45 to 9:00 minutes in

Hi

Do you disconnect the multi plug or also the black wire?

From memory (2006) it goes MAF to distributor and being black just disappears against other wires and looms.

My car did something similar and the black wire had come off

Ian

The black wire to the airflow come disconnected?

I would think so hence my check the earths comment a while back.

Could the plugs be too hot a grade ….I cannot see where you mentioned what you had fitted. I seem to remember BPR6ES plugs.

But memory fades

Ian

Is it perhaps something simple as a bad earth/ground connection

Perhaps try a couple of jump leads to back up existing battery to chassis and chassis to engine.
Not sure how many time things end up being a bad earth

Ian

Are you getting cross firing? So the HT wires cross over coming out the distributor.

When in the dark…start the engine and see if there is arcing between some wires.

Not sure your pressure cap would fit on the first plastic tank, the second looks like a standard cap fitting For your suggested idea the top radiator overflow would have to go to the bottom of the header tank so that it runs uphill from radiator so any bubbles generated will float upwards to reach t...

As a restrictor I used a bit of barthe diameter of the hose with a 2 mm hole drilled through. Many ne was a 1/2 inch hose so actually used a plumbing copper pipe with a stop end soldiered in place then drilled the 3 mm hole If the top hose is at say 90 degrees any flow from top of radiator is thus 9...

The way I read it the expansion /header tank now forms part of the flow of your system…..from radiator top and manifold top to tank to bottom hose so the heat of the fluid out the engine will be the heat of the header tank. I would also put in some restrictor to allow minimal flow to clear any air b...

Where does the MS pick up its firing point? Presuming a toothed wheel with a tooth missing? If so is the MS actually fire the spark? At the gap, at the next tooth or something like 15 degrees after the gap…….I seem to remember reading about 20 years ago it was the third option above. So the MS could...

Welcome to the mad house…that car sure looks like a bundle of fun

Ian

I would expect a helicoil is the way to go

Ian

This was a known fail point…so much so that in high performance and higher revving engines they fitted an external oil feed to lubricate the gear.

Ian

I had a leaking core plug….always was dry but “salts” deposit gave it away.
