Mine went in the top of the front inner wings, the section the outer wing bolts into along the side of the bonnet. Also I've had trouble where the rear seat belt mountings bolt through into the rear arch.

A note on petrol:  Esso Supreme 99 + is ethanol free in many areas of the UK, but check the Esso website to see which areas.

This is the current website notes on 99 which identifies the areas.

“Although our pumps have E5 labels on them, our Synergy Supreme+ 99 is actually ethanol free (except, due to technical supply reasons, in Devon, Cornwall, the Teesside area, Scotland and NW England). Legislation requires us to place these E5 labels on pumps that dispense unleaded petrol with ‘up to 5% ethanol’, including those that contain no ethanol, which is why we display them on our Synergy Supreme+ 99 pumps.”

Some progress!

New tensioner bearing arrived from Mark the other day so now I’ve changed the timing belt as well as tensioner bearing! Looking nice and clean now as opposed to the rusty mess that it was before. And changed the oil and filter, plugs and fuel filter. Turned it over without the sparks connected to establish oil pressure but no luck! The gauge seems to be working as a little blow through the oil pressure line shows pressure. The gauge is showing some signs of life when the engine is turned over but no where near what I’d consider necessary. Also on that note, not getting any fuel into the fuel filter despite a full tank! Any idea why? Will post some photos soon!

Cheers guys

The line you blew through is not oil pressure but is oil level. It connects to the top
of the dipstick. Oil level gauge is top right.

The oil pressure gauge is top centre and is electrical. It's worth getting a new sender,
it may be blocked.

Try sucking the fuel line to see if its flowing ok. Old fuel lines can collapse internally, it's worth
changing all the rubber sections.

Regards
Nigel

edit to add: just remembered yours is an early car so gauge positions may vary.
Also, how old is your fuel, did you drain and clean the tank yet etc.

That makes a lot of sense 😂! Drained all of the old fuel and luckily it was put away with a fairly full tank! After draining, I noticed the tank looked surprisingly clean, therefore figured I’d be okay to do without taking the tank out and cleaning it. Will make sure to change the fuel filter a few times to start with! The fuel in the car right now is brand new so that shouldn’t be an issue! Wanting to replace the fuel lines but figured I’d test it first to see if I can get the car running before doing that. Thanks for the advice though! Is there anyway to refurbish the oil pressure sender? Or easier just to get a replacement?

Cheers

When you turn the ignition on do you get a red low oil pressure warning light on the dash? Does that go out when you're cranking the engine on the starter? If so the pressure sender on the block will be faulty (assuming wiring continuity).

You say you turned it over without the sparks "connected". When trying to get some oil pressure up I would think you need to do it without spark plugs fitted so it cranks at a higher speed. The other thing to bear in mind is the tendency to register very low oil pressure at low engine speeds. I thought my first Beta needed an engine rebuild till someone explained that the indication of failing oil pressure at tick over was quite normal.

It's not possible to open the oil pressure sender, and new ones are quite cheap so go for that.
The larger of the 2 senders on the oil filter block is the pressure. The smaller one is the warning light.
If you ground the warning lamp wire at the engine end. the light should glow. If not, check the bulb in the dash.
If it still doesn't glow, you have a wiring issue.

In any case, changing all the dash bulbs is a good plan as then you're starting from a known quantity.

Looks like you dodged a bullet with the full tank. Rust is much less likely during storage.

I think there should be 3 senders on the oil filter block? At least that's my memory from 30+ years ago. Oil pressure gauge, oil pressure warning light and the oil temperature gauge?

And if anyone needs the union that holds 2 and is secured to the oil filter block by the third sender I think I have one somewhere in the garage.

Exactly right Guy.

I forgot about the temp sender, and its gauge.

As time and various mechanics hands goes by, these wires can become accidentally swopped around.
So if suspect readings are noticed, it's worth checking that first.

The Classic mechanics solution here it to fit a good quality capillary Oil Pressure gauge for testing. The Race Tech ones are excellent and will tell you the truth unlike the OE sender and dashboard. The OE senders fail over time but at best the OE gauges are vague and slow.

The engine does need some turnover speed to generate oil pressure and beware oil filters without the anti-drain back flap. These need a lot more cranking to get oil pressure which is not a good thing.

Thanks for all that info guys! If I’m cranking the engine with the spark plugs out completely and an oil pressure gauge in place of the sensor, what sort of psi should I be looking to see?

The Low Oil Pressure light goes out at 14PSI  on a Beta. If you see 15 -30PSI cranking you are doing OK. The pressure will come up on starting in seconds.

On long standing engines a light pre oil of the cams and the bores is sensible but expect a white cloud on starting!

And any brand recommendations for a new oil pressure sender?
