Just been having a little tinker and took off the air ducting unit. The hose itself has several splits in both the ridges and troughs so am going to give the self amalgamating tape (not too tight though as per Pomeo's ? recommendation) a go. Tick over is a bit variable, sometimes 600 others 900, sometimes "bouncing" - I have yet to ascertain a pattern to it. Also at times throttle response seems sluggish irrespective of STR on or off and having done an ECU and throttle reset.

One the the screws was a pain to get out of the filter housing and it turns out that all 4 brass threads have "parted company" with the plastic but the screws themselves have rusted inside the brass threaded sleeves.

Any suggestions as to what the best "remedy" is? I'm not sure if there is much to be gained by trying to get the brass sleeves off the screws. There is some purchase with the brass threads into the plastic air filter housing but not sure if there is enough to keep the housing "closed" in use. Or perhaps that isn't important??

I welcome your comments :)

I would see what the revs are like after repairing the inlet pipe as any leaking would cause extra air flow from what the maf is reading / sending to the ecu. Then the maf would be next to clean / replace and then a ecu reset again.

Many thanks for the reply Paul - I did wonder about the MAF but as she pulls fine up the revs etc - I wasn't so sure....

I had this on Mrs Avocet's old 156. It's infuriating that Alfa were so stupid / penny pinching as to put two dissimilar metals in electrical contact together like that. Like the OP, I only discovered it too late - once they were irretrievably seized. I've no idea whether the 166 filter housing is similar enough to the 156 housing for this to work, but I ended-up pulling the whole brass insert out of the plastic and then tapping the female hole left by the insert in the plastic housing with whatever thread (I think it was an M10 or M12) that was suitable for the hole left by the insert. The plastic is surprisingly strong and was able to hold the lid on the housing with no problem - it was like that when we sold the car. Obviously, if any of them aren't seized yet, the solution is to buy some brass bolts on eBay and fit those instead of the steel ones.

Apologies Pomeo and of course to Niall or the respected individual who suggested it :)

Thanks for the tip on Avocet - will try to get that sorted over the next few evenings.

One a side - got the new heart & badge fitted yesterday - it brought a smile to my face. (The wife simply doesn't understand) :D

Quite! I picked one up for the 164 at the Spring Alfa day and she asked why - "...after all, you already know what it is"!

They just don't understand...

Sorry 'bout your screen, but I had to admit to seeing the funny side myself!

Don't worry about the screen - my own fault for reading a post whilst swigging coffee at the same time.

The "self amalgamating tape" repair has made a world of difference - pulls deliciously. One problem though now my engine light is on!

Have checked the MAF wiring connection and that seems secure. Coincidence or something I missed?

Have you done a ecu reset after the repair?

See - I did miss something :D

Truth be told - it started to chuck it down and the rainfall radar showed it would be wet for a while - so I decided a glass of wine was a better use of time.

I suppose that would make sense as the " air mix" will have changed significantly since and so the ecu might think - "ay up chuck" (or whatever the equivalent would be) summat has changed big time here...

Thanks Paul :)

:cheese::cheese::cheese:

The Goldilocks approach does sound like me.Used successfully on cv boots but I have never had to tackle the air hose.However a 2 litre coke/pepsi/irn bru bottle and sticky back plastic my be my way.Too much BP as a youngster.

No apologies needed...perhaps twas Niall
