OK, so my machinist has admitted that they can't find an exhaust valve for my prothe 8mm aaz head.
It's up to me to buy it.
From searching here, it appears that the VW Part number is 074109611 - $37.70 + ship from 1stvwparts or who knows how much from my local stealership.
As for aftermarket valves, it appears that AE and TRW both make them?
The AE part number - which also appears as a Sealed Power part number - seems to be V91334. RockAuto says that this has a 7.950mm stem and is 95.100mm long.
partsgeek, we're all aware, obscures part numbers. But they show their part number W0133-1734357 as an AE valve that is 95.5mm long for a mid 90's 1.9l engine.
They also show their part number W0133-1735138 as a TRW valve that is 95.5mm long.
Both on this list: http://www.partsgeek.com/catalog/1996/volkswagen/golf/engine_mechanical/exhaust_valve.html
prothe claims that the aaz takes 068109611L but everyone else thinks that is a 1.6L hydro valve?
-
I cannot help on your question, but you could get 7mm guides and use TDI valves IIRC. The 1.6 had smaller valves so they should not work or work well in the aaz application.
-
So what all is need to convert to 8mm valves? Just the valves and the valve guides?
-
I quickly plugged the number into autohausaz.com and it offered a result for under 15 clams. Go look.

Yeah that's the AE part. I was about ready to buy it when i saw some discrepancy with the length of the valve as specified by various people and/or sites.
I might anyway, and then have the guy building the head double check the length vs. one of the valves i have.
-
the TRW part number for an 8mm AAZ exhaust valve appears to be 33049
Actually, I checked the Febi number on this list and it looks good too:

"W0133-1734357" is a www.worldpac.com part number.
Lot of people distribute stuff for them.
A few years ago they pulled OE part numbers from their software
that resellers use alltogether. You could search a OE PN and it would translate to a result,
but if you looked something up by application it only showed the custom W0xxx number.
Kind of a ***ty move. They might have gone back but
I quit using them at that point.
-
probably will need new springs and everythings to convert as the later stuff used dual valve springs?

the AAZ valvetrain i bought from mkpook came with dual valve springs. *shrug*
gonna order a valve today and hope.
-
ordered the AE valve as p/n W0133-1734357 from partsgeek just now. $24 shipped. here's hoping.
-
Well now I'm stuck.
UPS dropped off the valve, i took it to the machinist, he measured it and it came up short. literally.
my OE exhaust valves measure 96.8756mm overall length, the new AE valve measures 95.0468mm.
Package has AE logo all over it, AE part number V91334, and VW part number 074-109-611.

Are you sure about the measurements? .0001 mm is in the millionths of an inch range. (.000001") He does not have a mic that will measure that small, so how did he come up with the length.
-
Technically he measured 3.814 inches and 3.742 inches, with snap-on digital calipers. While i watched.
-
calipers are only accurate to .005"
When he sets it up he will have to put a thicker shim in it and that should be all. I don't see the issue, what am I missing?

I'm a n00b, but, do hydro heads have shims too?
-
Can with Crespo lifters. More money though.

I'd rather just have the right valve.
The boss at the machine shop is in a state of disbelief over the situation.
Or at least he's affecting one. I have it on good authority that stuff goes wrong all the time when building engines.

VW part no 074... is correct. However, correct length for Exhaust 8mm, pre 1985ish is 95.5mm.
Inlet valve is 95.6mm.
Engine 1Z has 96.85mm for both inlet and exhaust. Thus you have wrong valves, and they have sent 'wronger' :o. Calipers needed to read 3.76"

I think they do, I am a mechanical only guy. Never had a hydro all the way down, but it would seem they could not just put the valve in without setting it up initially. The lifter would account for wear, but I would think that the varying valve lengths would have to be dealt with in some way. That maybe a bit much what you have but still there should be something.
-
No shims whatsoever on hydraulic engines. The magical lifters take care of everything.

1z would have 7mm stems though, right?

These AAZ heads, and changes made along the way are definitely confusing (8mm vs 7mm, single versus double springs, etc).
I had excellent service from techtonics tuning when re-doing the AAZ head for me.
They had the same issues with different valve lengths, but they were able to get me the correct ones.

It would appear that for the 1Z, 8mm to 7mm changeover was about feb 1996. No length change.
AAZ changed around November 1995. What a 'Cluster F...'

Huh.
Got a part number for an 8mm 1Z exhaust valve?

Ah, maybe not exactly what i am looking for, but perhaps I am on the right track finally!
for a 1997 jetta turbo diesel, RockAuto lists AAZ, ALE, and AFN engines - ALE and AAZ with 7.950 diameter stems - and lists the AE part number V94011 as having a 7.950mm diameter stem and 96.850mm length for an ALE or AHU engine!
I think i just figured out where my valves came from!
'course, they want $30 to ship it from the UK.
-
Where was a 1997 Jetta sold? It really is a minefield.

Ahh, the wonderful world of VW IDI ;)
Mark could possibly clarify but "they" don't get much of that 30 bucks.

Turns out that rockauto has some weird blindness about the 1Z engine, but early 1Z heads had the same valves as ALE engines.
And new replacement 8mm valves in ALE/1Z spec dried up in the usa over a decade ago.
There are a bunch of posts about it over on the tdiclub fora, but i got kicked out of their 'club' so i can't post there.
It would be great to find a valve that doesn't need trans atlantic shipping but if i can't i will go ahead and order from rockauto on monday or tuesday.

$30 shipping isn't that bad these days. Autohauze charged me $56 across the pond over 5 years ago. So my purchase of $22 for four cylinders worth of rings, became 3 sets, and a bunch of other stuff. Still, VW [UK]was asking £100 per cylinder.
...I'm clearly not paying attention here. I thought you were looking for AAZ valves. Do you actually have something different?

Yeah, turns out i have an early 1Z valvetrain with my prothe AAZ head. And one bent valve.

You could knock out all the guides and go 7mm right?

Indeed. But i am experiencing some budget difficulty.
$44 shipped for 1 valve from the UK via rockauto isn't nice, but isn't horrible.
If i can get a used valve on this continent i'll go for it.
