Good morning

That picture looks like a single 4 barrel carb.

If this is the is the case I believe that the ports on the carb are not meant for this extraction work.

The more usual venting point is to the base of the air filter

Check if the relays click when you power up…..chances are the relay has failed / not connecting in the socket.


Or one of the earths has come disconnected and once cranked being back fed through another system

Would be my guess

Why reinvent the wheel?

That said there used to be a sponsor of this site that did poly engine mounts that were firmer than the rubber ones

Have you searched the K&N site

Greetings from Scotland

May Santa bring you all the toys you desire.

Merry Christmas

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.

Ian

Around 8:45 to 9:00 minutes in

Ian

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...
