Great that you got the fuel leak fixed, hope I have also done so on mine (still need to fill more petrol in to know).

Nice touch with the key and remote :)

Sure, the bulb you need is a miniature bulb, 1,5 V, 0,06 A, 0,09 W and you can get it for example here on German eBay: http://www.ebay.de/itm/Miniaturlampe-mit-Linse-Steckfassung-1-5-Volt-0-09-Watt-/331309184747?hash=item4d2390f6eb:m:mP_r2UyCJjMGFki2vvaiptA

Guys, long time no see, I've been very busy lately, having moved and a lot on my head.

Head gaskets replacement currently ongoing. Some white smoke started coming out of the exhaust as I was warming the engine up in my garage and I inspected the car immediately, cylinder 4 had the gasket compromised. After my local Alfa workshop took the heads off, both gaskets turned to be nearly completely gone, so job done right in time. I hope I'll be able to post some more updates soon.

In the meantime I went through the wiring loom to the injectors and coils and replaced the insulation, protected the fuel rail with a thick coating as the galvanized finish had already faded and I wanted to keep it from rusting (not 100% satisfied yet, but it's protected for now and more cosmetic work will follow).

She will get 3 brand new coils to the rear bank as one of them is already bad, and some other minor details as well.

Hopefully will be back on the road soon. :wink:

A lot has happened since last posting: head gaskets done, new coils, injectors replaced with the newer 3.2 V6 type, new crankshaft sensor, new starter motor (separate story), a lot of cosmetics in the engine finally. I hope to post more details on the particular topics in time.

She is running good, there are however a few quirks to sort out. I hear a bearing noise from the engine, auxiliary belt pulleys are suspected as all others were replaced with the cambelt last year. I have a leak from the Viscomatic group (accumulator, etc.) which started with the cold weather we've had here. Probably pipes need replacing, gaskets as well. Will have a look soon.

The car is parked for the winter, so good time to get those issues sorted. :)

Pretty much unused, including the briefcase keys, all the original instructions, guarantee letter, and some TSBs. As you see, a rare module briefcase is included, together with the special TSB informing about it. There is I got it locally and was very lucky to hunt it down.

Nice package and paint work :)

Does the suitcase contain the Q4 specific modules? MA10A for Motronic, MA12A for 4WD, M30A for ABS (also for 33 Q4).

Any other work left on the car?

Your engine bay is really nice now - I will be aming for tha same colour combination.
What tape did you use for electric harnesses? I would also like to tide it up but I don't want to use something which will "erode" glue from engine heat that it won't be possible to remove it.
And also, what paint? It seems like with texture, not completely smooth - which is interesting and I kind of like it :)

No, unfortunately I'm not that lucky. :D I only have the following: M8B/GB, M1C/IN, M3B/IN, M6B/GB, M7A/IN, M8A/GB, M10A/GB, M12B/GB, M14A/GB, M2A/IN, M21A/GB, M24A/GB, M19A/GB, M12A/GB, M1B/IN, M23A/GB, M25A/GB, M2B/IN, M29A/GB, M11B/GB, M28A/GB, M25B/GB, M50A/GB, M21B/GB, M33A/GB. I'll probably have some reprogrammed though, I know user alfisty here can do it, I'm just wondering if anyone has source with English language?

Alfan wrote:Any other work left on the car?

Yes, burning points are not working ABS (spare from Alfist laying in a box), serpentine belt pulley bearings, Viscomatic hydraulic pressure pipes (have a leak, will make new rubber hoses). Nice to have things on my list are removing dents after hale damage 2 years ago, refresh underbody coating, refurbish side mirrors. To do in the future will be slight (at the moment) leaks developing from the oil pan and the rear diff (only wet, no dripping), and some other minor points.

I just remembered that I've also fixed my erratic right turn signal, which was sometimes working and sometimes not. Hazards were OK at all times and left blinker too. So I figured when I hit the dash in the area under the steering wheel it would make the blinker to function briefly. I've read this is a common and known issue with our cars, and that the relay is at fault. Correct, but caution: in my car, and probably in other Q4s, separate left and right blinker relays are nowhere to be found in the area right and below of the steering wheel, where they are in other cars together with a group of other relays. Instead, there is a combined, multifunctional relay in the main fuse box area. Can't miss it, it's the tallest one in the left lower corner, has 7 or so legs. Just open it (have to leverage equally from both sides) and reflow the base soldering joints, your problem will be gone. :)

I'm happy you've noticed my wiring job. :) I usually put some attention to details. In fact, if you look closely, you'll notice that I've replaced most of the visible bolts and fasteners with new ones (including the ones holding the false firewall). Regarding the wires, I have actually removed the old wrap, and most of the insulation of the wires was gone, meaning the copper wires of the loom were shorting between the pairs... Probably not helping with your erratic idle. ;) I used self welding tape from Mannol for isolation (wrapped each wire individually) and to patch up all sensitive areas, also connectors. The finishing tape is an automotive electrical tape from Tesa. At some point we are all due for wiring harness renovation (I honestly can't wait to have it redone at some point), but for now I'm happy with what I did, the quality is very good. Yes, I am very patient. :D

Regarding the manifold paint, it's a wrinkled finish. It's an excellent paint called VHT Wrinkle Plus, one can is enough. It has a fantastic applicator valve, not of the cheap type, so you can lay it down evenly and thick, couple of layers just so it doesn't drip. It then has to dry for 24 hours, and then you cure it with a heat gun, that's what I did. Wrinkles are always good for this extra bit of surface area to help with heat. I did it because I like the finish, kind of how Lancia did it, but also you can't keep the old aluminum in a representative shape to be honest on a normally driven car. I just cleaned and decreased the surface gently, so I can always go back to the original aluminium after bead blasting it if I wish, no wire brush or any other harm done.

Sorry for the essay. :D

I nice post - lots of good information, thanks a lot :)
I have plans to re-do the wiring harness renovation as well + some other stuff in engine bay during the summer - will probably take a week of holiday at work because of it :D
Anyway I hope you won't mind if I would "copy" your color+finish scheme :D :)

Of course not, I'm glad you like it. :) I'm very happy with the result, during the last technical inspection once the guy saw the engine, he saw no need to investigate the car further. :D

While you're at it, it's a good idea to renovate your airbox assembly. Mine had broken rubber bushings and some rust. While you can get new bushings from Alfa, most probably you won't be able to get the old ones out of the base plate. I've fixed the rubber pieces with a bit of automotive glass adhesive, or window glue. I've also used the same adhesive to reseal the plastic airbox feed pipe after having the two halves powder coated. Correct rivets for that are 4 by 8 mm. The correct color for the airbox is RAL 9006 white aluminium.

Actually I did the air box already - it was in terrible shape - paint was pealing of it all over the place (also inside), so I cleaned it completely and painted in black (I like darker tones in the engine bay :)). It's almost perfect - just in few small spots old paint just did't came of no metter how hard I tried :? Probably will have to re-do it later on anyway.

I also considered black or darker gray, or even the wrinkled finish, but in the end, after much consideration and a couple of trials, I went for the original color which works well for me.

I also tried to remove the original paint, but my airbox had only surface rust in just 2 or 3 small areas where I presume water used to collect. Elsewhere removing the paint was impossible, even with a heat gun, it was very strong. In the end it was stripped chemically before powder coating. :D

Superb reading and great to see another considerate owner wanting to save another great Classic Alfa 164. The photos look fantastic, especially the dealer ones. The shape of the 164 truly is timeless. Beautiful from all angles. Well done !

I used self welding tape for isolation, wrapped each wire individually, also to patch up all sensitive areas and connectors, something like Mannol 9917. The finishing tape is an automotive harness / electrical / cloth tape, like Tesa 51608 or similar with different width.
