Oops, I forgot we require login at 1stgen.

Valve seals - Engine Builder Products Enginetech Engine Kits Engine Parts Engine Rebuild (Hi-temp viton valve seal, 11/32" stem .582 Guides , Part # S9210-20)

For those interested the previous link is a list of 18RG parts sources I compiled. Many you know, but there are a few surprises. Bollox on 1stgen has many contacts no one else has heard of as well.

[Willofan]

No luck on the valves, SI industries are out of stock for about 3 months.

I will keep trying and register on 1stgen to see what is there. Thanks

guys, a question on 18rgeu's.
I have a full efi set-up, with surge tank, lift pump, filter, Raising fuel pressure gauge.
My question is, once the engine is off, should the fuel pressure stay up.
i have it at 45psi, so far. but when ignition is of it drops to zero.
i have no fuel leaks anywhere. What could it be?
could it be a faulty fuel pressure guage. It does all the right things, like increase and decrease fuel when adjusted.

Do you have a check valve after the fuel pump?

[o_man_ra23]

The fuel pressure should drop to zero when you stop the motor. There is nothing in a normal system which should hold up pressure. The high pressure pump will be an axial type which has a path for fuel to return backwards, which is why your pump should run for a couple of seconds when you turn the ignition on, to pre-charge the lines.

[Javal]

Also the regulator will allow some bleed-off with zero vacuum. Totally normal.

Hey guys, thanks for your assistance trying to find some valves.

As luck would have it, I was going through all my boxes and putting all my engine stuff together and found an old toyota packing envelope with a parts order/picking date 02/03/81 on it from York Toyota. Inside was a brand new set of 18RG valves still in the little brown bags and in pristine condition.

I just won lotto, also found some adjustable vernier cam gears too. Oh I love Christmas when it comes early...

Tossing this in for your amusement. The block of the 1127cc Triumph Spitfire engine was sourced from a Massey Ferguson tractor, true! The "Old Grey Fergie" was turned into a "sportscar".

It's good to hear this is normal. Thanks o__man.

Ra_28, no I don't have a check valve. I presume it's stops the fuel from flowing the other way.

I just assumed with Efi, that the pressure stays up.

With the 18rgeu I have sitting in the shed, would these carbs be suitable?
OER 45mm carburettor, Solex jet type otomoto.com.au
The current ones are fubar'd and IIRC the throwaway type.

It's a long way away from a rebuild but finding them on the site has me somewhat excited.

Hi,

The current ones are fubar'd and the throw away type????

I didn't know there were throw away side draught carbs. All are pretty expensive and can cost a bit to get rebuilt, but never heard of a set that you chucked, rather than get fixed.

If you do decide to throw them. Box them up and throw them my way.

Rodger

[MorgzMods]

I'm no expert, I vaguely remember one model of RG had carbs that couldn't be rebuilt? If Rodger is happy to correct me then I'm happy.

I'd rather use what I have than purchase new ones. Maybe Rodger could flip a PM with a cost? I sent a PM a while back but never heard from it.

[lilcrash]

I've never known toyota to have anything throw away spec. The link you posted are basically the same carb as stock apart from being bigger.
