David I´m sure, checked it twice before taking the head off. The dizzy spunn 1,5 turns when the engine went one (1). This is because the dizzy isn´t placed there on the 164. It´s on the back of the left cyl. bank, so it doesn´t come into play.

The engine is out of a ´91 164 3.0QV (S)
Thanks for the tip about plugging the hole, will do!

Seb,

No Probs, my 164 FWD 3.0L had the Dizzy on the head, but only needed the oil pump changing due to the screw and washer on the drive shaft.

By the way, while you have the head off the 3.0L, what markings are on the cam shafts. I'm trying to find out what's in mine with markings as per the following.

I will have a look David, next time I´m in the garage.
I would think the "S" means you have the cams from a QV (S) engine. (200bhp stock) Thats what I have since my whole engine is from a 164QV .

David!

I´ve checked out my cams and they seem to be the same as Yours.

One says 30 31 and the other 30 33. I can´t find a marking like the "S" you have, but thay are prutty oily. Hope You have any help from this!

But now, I have a problem, maybe one of you can help me.

Im trying to get the cam wheel off, but its stuck as hell. I´ve used a puller, banged on it, heated it, ripped my hair out and puked blood! How do I get the little fu**er off?

I´ve loosened the center nut, and the three bolts in the plate outside the wheel. The wheel is loose and is ratteling in an anoying way inside the plate, but the plate doesn´t move!

If anyone of you hav e good tip I´d really appreciate it!

Seb:
I seen you try to pull on the hub. I just loosen the center nut and pull on the wheel itself. Just tighten up and give the puller a hit with a hammer now and then.

Jarle!

I tried that first. But since nothing happened I changed taktics. I wasn´t sure how much force the wheel could handle. I pulled hard on it!! And banged on the puller shaft. Well, I´ll keep trying...

Thanks for helping guys, excellent!

These wheels can handle a lot of power sideways. I ensambled 4 set of heads last week an all of the wheels came of after some rough handling

Seb,
In my experience you have to keep releasing the puller jaws and rotate around the "support hub" so that the pulling force is distributed around the circumferance.Once you've gone around once set your puller and crank it almost to the point where you think you're going to break the hub or the puller.Be carefull because when it pops off it will fly across the garage.Ask me how I know this !

Seb · Post by **Seb** » Tue Dec 28, 2004 5:41 am

OK, thanks guys!

Murray, did you pull on the hub or on tha wheel? My puller doesn´t grip to well on the hub. If I crank it too hard it slips. In that sence maybe it´s better to pull on the wheel itself. (?)

I didn't read the whole thread but did you guys know there's a factory Alfa tool for this? It screws into the 3 bolt holes on the balance plate in the front of the cam sprocket sort of like the steering wheel puller.

Perhaps 3 bolts into a home made tool would be better than the 3-jaw puller. The sprocket itself is very soft metal.

The best would be to find someone local to you has the tool you can borrow. You'll need the cam locking tool and cam turning tool too when you go to reassemble.

Have a look at http://alfa.denovich.org/twiki/bin/view/Alfa. There are directions to make at least one of them.

Peter!

Why do I need the tools to reassembly the wheel? Isn´t it just to put it back and tighten the center nut?

Maybe I´ve missed something here.

When you go to install the heads and belt back on the block, you'll need the cam turning tool to line everything up and the locking tool while you adjust the tensioner. Do yourself a favour and use a rebuilt hydraulic tensioner (see the rebuild tips I posted on another thread).

Don't install the factory valve bending tool (thermo-mechanical tensioner).

A couple of other notes:

AAV:

The Motronic uses an IAC (idle air controller) thats stepper controlled based on CLT, IAT and load. It's the big solenoid looking thing on the long side of the plenum opposite the runners. It uses pulse width modulation to control the valve opening. Motronic doesn't use the AAV which is thermo controlled and not even connected to the primitive L-Jet except for a ground wire that activates it when powered on. The IAC controls the amount of idle air in all conditions warm or cold.

I would highly recommend an aftermarket engine management system for a project like this.

David in Brisbane:

That is a nice project!! Nice job on the runners. I see a lack of an AFM. What speed/density system are you using?

Duh, never mind. That's the MS install I helped you with. I hadn't seen any underhood pictures. We tuned Davids car on a Sunday afternoon via the internet from Chicago, USA to Brisbane AUS.

See, Seb it can be done. Sounds like this Motronic install is a whole lot of work and grief for a stock system. If you're going to feel the pain, you might as well have the gain!

Thanks Peter!

On the engine I´m using/converting to, it is a hydralic tensioner, isn´t it? It´s a 164 3.0QV from 91.

About the AAV. Thanks!! I could use some more help concerning the Motronic, You seem to now.
