Fitting SPA gauge for oil pressure and coolant temp

[billybradshaw]

Morning all,

What't the craic with fitting the SPA gauge? It looks like I'm going to need to buy / make some adaptors but I'm not 100% sure about what it is that I need.

Any ideas?

I think pmessling is the man to ask on here mate, goodluck with it as I'd like to do the same however I think I'll be letting the boys at power do it for me.

[pmessling]

I did make the adapters for mine. How ever I can't remember the thread types needed. I'm sure I can find out by the end of tonight and I'll let you know what I have to hand. At work so can whip some up on the lathe.

Think the water rail is bsp to npt

Morning Peter,

That would be a great help, thank you very much.

Involve me in that too please Peter

If you choose the oil temp/water temp gauge, where and how do you connect to the oil lines?
Peter, I too may be interested in the part, if I can get my head around how its fitted!

This is the one I assume to buy
http://www.spa-uk.co.uk/Product/Oil%20TemperatureW...

I thought that knowing the temp of the oil may be useful in knowing when to safely floor it and I intend to get speedy's to repair my original gauge and leave in situ (I want to keep it fairly original). I'm thinking of locating the spa gauge in the cubby hole. What's people's thoughts on that?

Interesting plan I think I'll go for the oil pressure/water temp (keep it in line with original values but with a modern twist) forgive my ignorance why is oil temp better knowing for when to floor it rather than the mix of water temp and oil pressure?

[Demondad]

I'm guessing with the oil at optimum temp then engine happy? I'm no engine technician but I think oil temp has to be a useful addition to know. Seem to remember reading on here once that due to water thermo stat water temp could reach good level before oil does during cold weather driving. Others probably know more.

The pressure fuel/oil/air etc sensors are 1/8 BSP and the temp oil/fuel/water etc sensors are 1/8 NPT

An oil stat is worth considering as well.

I have the sensor for the oil pressure in the V were the original feed pipe is to the gauge. It's unfortunately under the coil packs but a good time to replace the oil pressure switch at the same time.

The loom passes through the throttle cable gromit but to do this the square plug needs to be taken apart to pull it through.

Water temp sensor same place as the capillary tube was.

Another way to mount sensor would be to add an aluminium jointer between two of the coolant hoses

I have an oil temp gauge in the clock position with the sensor on a sandwich plate between the oil filter which I also added a test point to when my pressure sensor went. Piece of mind.

Both the temp and pressure sensors require adapters to fit which for the oil pressure raises the height that bit more requiring the coil packs to be raised by quite a bit as the plug on top of the sensor also adds to the height.

I adapted blacking plugs for the adapters I have the taps to suit it's just the blanks required that I sourced from work. I'll go and have a look now in my tool box.

[pmessling]

The water temp adapter is 3/8th bsp - 1/8th npt

[pmessling]

The oil pressure sensor requires 1/2 unf to 1/8 bsp

I couldn't get this one so found a 1/2unf blank and machined it to fit.

If people require this one then let me know and I can get some blanks unfortunately not something we use at work and machine to suit.

Evening Peter,

Please count me in for a pressure sensor adaptor.

Thanks for your help with this, much appreciated.

Right think i may have mislead with the 1/2 unf adapter.

I have done back though the information i gathered and the thread on detailing world of the work i carried out and whilst the oil pressure switch is 1/2 unf there are two holes under the coil packs one for the switch and one for the oil pressure take of to the gauge.

Looking back now the adapter needed is 1/4 bsp to 1/8th bsp which is easy to get hold of on ebay for instance

If you look on this thread page 8 i did also put the thread on here but this is what i done over winter a few years ago when i fitted the gauge.

Brilliant, thanks Peter, just ordered the adaptor so should be good to go once I've recovered from my hernia op.

Cheers

Speedy recovery Ian

Should you need any further help then just shout.

Remember because the coil packs need raising you'll need longer bolts and spacers to suit.

Thanks Peter.

I'm thinking I'll change the coils whilst I'm in there too. What do most folk fit, any ideas? Presumably the fuel rail has to come off to do any of these jobs.
