Anyone know who can supply unfinished valve blanks?
Stem size 3/8"

Haven't seen any since the days of Dufor but why can't you modify a
finished valve?

Quick Google search brings up this:

That was going to be my next comment. Rather than buy semi finished
blanks, which can be expensive, I'd put some time into looking for a
stock finished valve that can be modified to suit.

The 2 collets and spring retainers seem universal except for Lawnmowers...

Not really. The collet grooves vary a lot between manufacturers, and the
height of the groove on the stem is critical to the individual
application. Too low and the spring will have too much on seat pressure
and may bind at full lift, and too high and it won't have enough and is
likely to lose it's "clamp" on the collets and drop a valve.

Australia preferably, but might need to buy from anywhere else.

[Jordan]

Probably couldn't find them long enough?
The valves are 6+1/2" long, 1+3/4" dia exhaust and 2 +1/16" dia inlet.
It's for a 1926 Vauxhall.

Then again, maybe some truck has something that'd suit. We're not sure
how to go about finding them.

[Jordan]

Thanks, but they don't list 3/8" stems.
The guides have already been made, which seems to limit choice a bit!

[atec77]

have you spoken to your local reconditioner , if he can't help then time
to turn some

X-No-Archive: Yes

Have a look at the ones on old Bedford trucks. If I recall correctly
they had thin stems with a very large head in relation to stem size.
Have a feeling they were 5/16" diameter however. Could be wrong, it was
a long time ago...

Make new ones. It'd be cheaper.

I'll pass that onto the owner.

Type OD, OE or LM?
Just curious, as I once owned a Luton Vauxhall (griffin mascot and
all). :-)

I've probably got a listing by dimensions somewhere but there should
be a few around that size. I'll also have a look through the bucket
full in the workshop when I find it, provided you're not in a hurry.

Bit of a mess in that department ATM as we copped a wild storm last
week that flattened a couple of sheds and damaged others. Still
waiting for the insurance assessor before we can dig through the
wreckage.

Do you need inlet, exhaust or both?

Now admittedly what I was after was a bit more mainstream that what you
want

If you luck out with Ivam, try

http://www.intervalves.ch/index.html I don't know if they sell blanks,
but my old BMW has a set of their valves in it and they have well and
properly lasted the distance.


You could also try AE in England I mention them only because I am about
to fit some of their valves to an R65 engine I am rebuilding and they
are 2/3 the price of intervalve and motobins reckon they are good (so
does Federal Mogul who rebadge AE valves world wide).


Lastly, if you want a bit of fun

http://www.made-in-china.com/products-search/hot-china-products/Engine_Valve.html


Hint - when Chinese engine valves arrive, grip head in one hand and
collet end in the other - apply bending force. If you succeed, do not
use valve.

Seriously. Tell him that it is *way* easier to make new guides than it
is to make new valves.

I thought all you needed to fix valves was a bit of putty:-)

You apparently do if you're one of these fuckwit daydreamers who reckons
he can fit the "front end" out of some other model and end up with power
disc brakes in the process while not ever having to do anything about
the original unassisted wheel cylinders in the rear.

It would appear our resident space cadet has gone awfully quiet since he
made a complete fucking idiot out of himself in the "identification"
thread :)

They're made of putty and will be fine ;-)

It's a 30-98 OE, which I'm told is the OHV version.

It sure is, and the most desirable of them all.

I'd also be surprised if valves weren't still available in the UK
unless the head is non standard. Failing that there ought be no
shortage of valves that could be made to fit, including some in my
scrapbox out of a Fiat diesel (for which I could dig up the part
numbers). Only catch is the stems are 10mm but 3/8" are also common
in large diesels.

Alternatively if the stems aren't excessively worn it ought be easy
enough to resurrect the faces with Stellite (but make sure it's the
genuine stuff and not spray powder).

10mm should do if guides are reamed out.
If you do find some part numbers, I'll pass it on, thanks.
The head is non-standard aluminium alloy, to replace the original which
has a crack in it.

He's out there somewhere with his infinite gearbox, maybe in reverse going back

Intake dia is 2.01", exhaust 1.78". Length about 6+3/8". The intakes
could be stellited to increase the diameter and the length could be
increased the same way, or else with lash caps.

As I recall they weren't particularly expensive or I wouldn't have
replaced them. I'd be happy to donate a used pair for samples if you
supply address details (my Inbox address works so long as I know to
check it for legitimate mail).

They came from GW Tractors, who have outlets in Melbourne and
Brisbane. If you want to check availability and price beforehand they
suit a Fiat Alliss 14C, inlet part no. 4684088, exhaust 4684089.

I'd also suggest contacting a tractor mechanic, or a tractor wrecker,
who might be able to suggest something with 3/8 stems. I overhauled a
Ford diesel head with 3/8 stems not long ago but didn't replace the
valves and consequently don't have a sample or know the dimensions.

I used compressed air to keep the valves shut while I broke collet seal with a socket and hammer, then using bent-nose needle-nose pliers, I'd pick the collets up while compressing the spring with a large pair of tin-snip handles,.. and replace the valve-guide seal on the Hemi 6s. This curtailed about 70% of the blue smoke on start-up :-)

Hi John,

Your suggestions all sound practical.
I think the owners will try to find some that don't need as much
modification, but if that doesn't work out, your pointers may be invaluable.

Thanks,
Jordan

It's actually no more difficult to modify (and resurrect) with
Stellite than it is to machine blanks, but I guess that all depends on
what resources you have available.

You're also talking about a car that's probably worth $250k or so, if
it's anything like a reasonable example. The 30/98 is regarded as one
of the greats of its era. First production car guaranteed to do the
ton and right up there with Bentley (they were around the same price
new).

GM acquired Vauxhall around 1927 and turned 'em into shit.
