I'll see if we may have a club member who has one and is willing to part with it. There are quite a few with both 33's and 75's so I may be lucky!

Took the valve out and connected the outlet from the canister with the corresponding inlet to the manifold and the noise is gone. Thus, obviously it is the valve that's the culprit. The question then ...

Thanks for the suggestion!

I found the valve (mine is partly orange and mostly black) and took it out. It apparently closes the connection between the cannister and inlet manifold when there is low ...

Hi all!

My '90 1.7 ie has started making a whistling noise. It's the vacuum tubing from the inlet manifold which ends in the fuel fumes carbon canister. At idle it's vibrating and I wonder if there ...

Since the last post I once again MOT'd it and the emission values were just a out-of-line as before. CO 0,7 (0,5), CO @ 2500 rpm 0,6 (0,3) and HC 218 (100) with limits in brackets. Lambda was the only ...

Update:

Finally gave up and handed it over to the local Alfa-guru. He removed and reinstalled the manifold and it is now guaranteed not leaking. He didn't think it was before either. Also set the t ...

I think that's the next logical step!

I know the timing needs to be adjusted and the intake gaskets would be the only items not changed. Also need to make sure the bolts are tightened to the correc ...

The work to find a solution has continued but the problem remains! I agree that everything points to a "signal" missing for the CU in order to find the correct idle speed.

Consequently I ...

Friends,

Had to disassemble the intake earlier today in order to free up the distributor. Prior to the "operation" I had a somewhat uneven idle and disastrous emission numbers. Thought I' ...

Is this what you need?

... and yes -- there was of course no need to remove any cam cover as descibed in the shop manual. Have no idea what that refers to, except that it's a relic from the earlier models!

Being a cheapskate and assuming that the tensioners couldn't have gone bad in 60k km's I happily got all the way ready to replace the belts -- only to see that the tensioners had bits missing fron the ...

Then I wouldn't have been more confused than usual!

But they actually mean the camshaft housing! No 1 in this picture:

Now it's time to turn the attention to the timing belts and replace them. Seems to be straightforward enough. Especially with the hydraulic lifters where the cam marks are on the pulley rather than th ...

Just a follow-up to report that the 33 has now passed the Swedish MOT-equivalent with flying colors and quite a few appreciative remarks from the inspector. Actually it drew a small crowd of personnel ...

Yes, you were right while I was barking up the wrong tree!

I also assume the brakes just need getting everything moving freely and greasing them!

Problem solved Laughing

Had nothing to do with the fuel supply whatsoever! Someone in the Swedish club suggested checking the resistance of the spark plug wires as well as making sure the wires were ...

Yup! Sparks from all four plugs. Used both an external spark plug tester as well as unscrewed the sparks and checked!

Since posting I have now replaced the ECU (the control box on the firewall) wit ...

I recently picked up a two owner, rust-free 1990 33 1.7 IE with cat and only 36k miles on the meter. I was driven regularly for the first few years but from around 1995 to about 2005 only got less tha ...

Being about to post a question I feel compelled to introduce myself first.

I am currently the Secretary of Club Alfa Romeo Svezia (www.alfaromeo.org) with some 2100 members.

Have had a variety o ...
