The V8 Owners Forum -

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

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.

Ian

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.

Ian

I hate to say it but if you have stripped the gear on the distributor I see a complete engine tear down, clean and check. The metal that was stripped of could have made it anywhere in the oil ways. So any bearing would now be suspect in my opinion. Sure the oil filter should collect all the debris b...

I ran a 3.9 with 14CUX and lambda sensors and no cars in my GT40. The engine was extensively worked over by John Eales and it had a JE102 cam which had huge overlap and half inch lift Tried numerous tune resistors and 3 different ecu’s and it always had a bad dose of kangaroo between 1200 and 2000 r...

Hope you did not use ptf tape on the threads of the sender…. It may have slightly intermittent contact

It may seem strange question but have you checked your voltage both battery and after the voltage stabiliser that should bring it to 10v from memory for the instruments. Obviously would need to be done when on the move so may be a tad difficult. If the voltage fluctuates I would suggest trying a dif...
