Re: Series 1 3.8 low oil pressure after fresh engine build..Help!

Have you tried running the engine with the mechanical gauge fitted, or just cranking, and if only cranking, was it with the plugs out to get maximum cranking RPM? How badly split was the o-ring? I suppose if the pump is drawing air in as well as oil, you’d get aerated oil coming out of the pressure ...

Re: Found a head.. is it from an E type?

What are the numbers on the rear of the head? Maybe others with S2s could compare numbers? I’ll have to check mine at the weekend, I can’t get the bonnet open with the car where it is at the moment.

Re: Long stud straight port head....or short?

Cam covers might be easily swapped, but a later head designed for a cover without the cutout won’t have the extended bearing cap for the rear of the RH camshaft. Bearing caps are matched to the head, so they shouldn’t be swapped between heads. That leaves the options of fitting a later cover, or man...

Re: Engine chugs when power is taken off

It’s difficult to diagnose without more info. How low revs are you talking? What speed are you going? Does it do it in all gears? What condition is your car in? Has it always done this, or is this a new thing?

Re: Long stud straight port head....or short?

That does look smart, pity it’s not the correct spec for you. I don’t know how you identify a big valve head from the outside. Measuring the valves when it’s removed would confirm. It does look like a later head though. You have the later style cam cover on the RHS, with the half moon bung filling t...

How about this one? https://rover.ebay.com/rover/0/0/0?mpre ... 2973326856

I don’t know anything about the seller, just spotted it on eBay.

Incidentally, does this mean you have an S3 xj6 big valve head you’re looking to sell?

Re: Trouble shooting 123 dizzy

My 123 wasn’t good to 20v. At about 15v, it causes the ignition to cut out, thought it doesn’t seem to have caused any permanent damage. I had a faulty relay in the alternator circuit, this caused the regulator to see a lower voltage than the alternator was putting out, and concequently the car got ...

That would help. It’s quite difficult to see exactly what’s what on a mobile screen. Was there ever a wire on the terminal with the yellow arrow?

Re: Starter wiring and solenoid questions.

It looks from your photo that your white-red wire is connected to the same terminal as the main battery positive feed. If that’s the case, then the car won’t turn over as you’re just connecting the switched 12v feed to a point that already has a permanent 12v. On the original ballast resistor wiring...

Re: Starter wiring and solenoid questions.

Which wiring diagram are you using? It took me ages to find one that included most of the extra US spec S2 bits that don’t show on the standard diagram. Does your car have the seatbelt warning system? This interrupts the starting circuit, so could have been bypassed. Is the terminal on your photo in...

Re: Thought and Contemplation

I think there will be a generation of cars soon that, with a few exceptions, never make classic status. They’ll be too complex to be fixed at home, and too expensive to pay specialists to sort out, compared to the value of the car. I think younger enthusiasts will then look to more established class...

Re: Alloy radiator for Series 2

They’re not standard S2 fans. They’re probably a standard size Spal fan or similar from a catalogue, rather than off another car. I expect they shift more air and draw less current than the originals. The only downside is they don’t look particularly period correct. Do they work alright?

I bought a 2nd hand standard S2 rad off someone who was swapping it for an alloy one for no reason other that the alloy one was perceived to be an upgrade. I cleaned it out with kettle descaler which removed quite a bit of crud, and had to replace the studs for the otter switch were snapped. It is m...

Re: Trouble shooting 123 dizzy

That doesn’t sound right, check the wiring diagram here. http://www.123ignition.nl/product.phtml?id=270 Without it on the car and cranking, you won’t get it to work properly. It detects when the engine isn’t rotating, and cuts the circuit to the coil to prevent the coil burning out. Even if you rota...

Re: Valuation.

I think you’re after a couple of different things here. An insurance valuation should represent what it would cost to get a similar condition and spec in the current market. Any of the specialist clubs should be able to do this for you, or you can sometimes self certify depending on your insurance c...

Re: Valuation.

E-types don’t seem to neatly fall into the condition categories either. Most are either shiny and well presented, or complete restoration projects. You see very few tatty but perfectly usable cars. Of the shiny ones, some when viewed closer aren’t so great, probably have some nasty bits lurking unde...

Re: Valuation.

I don’t believe all of Hagerty’s values. By their description of condition, many aspect of my car should fall into the “fair” category, but I defy anyone to find any FHC for under £27k, let alone one that could be driven home without issue. The valuation for “good” is a bit closer to the mark at £44...

I thought the 123 had a built in cut off to protect against the ignition being left on.

Re: Trouble shooting 123 dizzy

Is your car positive or negative earth? I’m assuming nothings been disconnected or changed since it last ran. I’d look at the simple stuff first before condemning the 123. Do you have a spark if you connect a plug into the king lead? This would indicate a rotor arm or distributor cap problem? What’s...
