Just yes + modifications or no not a chance please!
Will a TDI ALH intake work with a Garett t3 turbo and 1.9 aaz head in my mk2?
1.9 aaz head with 8mm valves on a 1.6td hydro block? keeping the springs and lifters?
1.6 exhaust mani with the aaz head?
Please help me! I want to order my parts as soon as possible but i don't want to $#@^ up!

I have a complete 1.6TD with a garett t3
My order so far is
1mm over pistons/rings
1.9 aaz head
8mm valves
tdi intake + gasket
egt
cam and valve guides
-
I think YES to all questions, but someone more knowledgeable will chime in.
make sure the head you're getting is the 8mm one before ordering the valves, there are 7mm aaz heads
-
Yeah I know! That's what's been holding me up and is what is still currently holding me up. He seems to have 8mm intake valves but no 8mm exhaust valves.
does anyone reccomend against reusing valve springs?
-
a tdi intake will work, but if you want to use stock plumbing you'll want an aaz intake with a 1.6td elbow on it, then u only need to grind on the back of the intake a tad to clear the turbo. but if you're going to run an intercooler none of that really matters.
-
Yes i plan to run an intercooler sorry! i should have mentioned that.
Thanks for your input!!!
Really wishing Pete Rothenbacher would reply to my email now... Or put exhaust valves on his site...
tick tock waiting for exhaust valves.... do do do
Pete Rothenbacher says on his site that a replacement oil return for the turbo on 1.6td's wont work for the 1.9td (or tdi's obviously)
is that because of differences on the 1.9 block or the head? or a combination of both? ie. height of engine
I just want to check with someone who knows
Do i need new liners if im getting my block bored 1mm over stock?
bore and over sized pistons adds $500 that i don't have to the cost of my build. I can hone for less than 100$ and get new rings for my stock pistons. Can i do that? What are the thoughts of the people?
I really need to do this quickly so if you have any thoughts at all i'd love to hear them!
Edit: okay, minus the 1mm over pistons and over boring is SUCH a huge money saver so im not going to do that anymore. Just hone + new rings and hope for the best. Am i stupid for doing that? I really can't afford the big pistons and over bore ontop of the head
-
I really need help building this engine. Please someone help me?
Do i need a cam cover for a 1.9 aaz head or does the 1.6 cross over?
Can i use the same sprocket off my 1.6 head?
Do i need different hard lines?

you need the 1.9 cover & the hard lines. not sure about sprocket though...
-
Ok! thanks!
Prothe only sells 1 cam cover and it claims to fit basically all years. Doesnt give head types or anything just model and year... uhhh?

Also, anyone know where i can find hard lines for an aaz? Im trying very hard to avoid my vw import shop as it's very expensive.
-
Burn_your_money may be able to get you a set.
Drop him a PM..
-
Also I believe the 1.6 valve cover will fit the 1.9 but someone else will have to confirm to be sure.
Again, contact burn
-
Hmmm okay I guess he'll get two messages now haha.
Perhaps he'll resolve the dispute between jtanguay and zukgod1 about cam cover cross over
-
Machine new holes you mean? and mofify the gasket accordingly
Sorry, what do you mean by
The AAZ is mounted by three in the center that attach to cam caps.
I don't follow the cam caps thing... you don't mean the caps that hold the cam down do you?
-
Stewardc's Caddy with a 1.9TD.
Notice the nerds on the top of the valve cover. The nerds cover the stud&nut that hold the valve cover to the head. The studs are screwed into the caps of cam towers.

-
Ohhhhhhh I seeee
Uhhh. Couldnt i just fill the holes on the cam and ... not ... use the top studs? I don't have machining tools and i can't pay someone to do it.
absolutely SICK ride btw.
Just thought i'd point that out.
-
Prothe doesn't sell a 1.9 cover other wise i would.
But seeing as i already have a nice gasket and cover for a 1.6 I'll see if i can find a friend with a drill press.
Thanks SOOO much for that. That was a really big issue
-
A 1.9 valve cover will be the easiest/safest route.
I tried the G60 VC on my 1.9 head and the stud bosses in the cam towers interfeared with the valve cover.
There is also guide pin holes in the corners of the 1.9 head that are noticable eccentric to the holes in the 1.6 valve cover. So to do it right, those holes would need to be Tig welded, then the weld needs to be machined flat, then drilled, then tapped, then grind the bosses off the top of the cam towers.
-
Hmmm
Yeah I totally agree.
but I don't particularily have money for a 1.9cam cover/gasket.
but i have time to spend drilling if i can get my hands on a drill press
-
OK, but take a look at the Pics that Libbybapa posted again.
While the 1.9 head has bosses on the cam towers, it does lack bosses for studs along the edge for studs.
The webbing for the VC gasket on the 1.9 head 'might' be thick enough to hold VC stud, but I have some doubts.
I have the 1.9 head and both the steel, and aluminum G60 valve covers, and I'm probably going to give up and use the 1.9 valve cover.
-
Oh yeah ... good point. Geeze.
How thick is that? 1/4 inch?
I wonder if you could go backwards and change the 1.6 cover to adhear to the cam towers...
Yeah i may end up doing as you will. Depends how cheap i can get a cover.
-
If your close to Dave @ PP drop him a PM.
Heck if I was closer and had one I would donate it to the cause.
-
Wow thanks Dan! Even with my n00bulance you still support me :D
This site is the sole and lone reason why i still have a car at all. And why there is still 1 more idi jetta rolling around
-
Maybe if you have the room, you could drill and tap for a 1.6 cover but screw capscrews in from underneath the head to use as studs. That way they can't pull out. I'd locktite them as well if they will work.
-
Wouldn't tap-ing the cover only give you like ... a thread and a half? the cover isn't very thick. But i like your idea. With that in mind, im thinking of just doing a bolt method. Just since a short bolt and nut to sqeeeeeeze it together. no tap required.
How many would be excessive? 16?
-
OH man i just noticed the IP in that truck (picture on page 1) is painted black! that's so sick!!!

No, I mean tap the head and screw capscrews in from underneath(if they would fit that way) so you have studs sticking up out of the head. The head of the capscrews will keep them from pulling out.
-
Ohhh okay i see. The way i have my Cam cover right now is with little studs into bigger holes with fresh taps because mine were stripped. Id they were long enough to put a nut on that would be even better. Thanks Jim.
