not sure how i missed this incredible thread ! loverly car OP, and looks mega on the alfaholics kit.
i have a real soft spot for this era of alfa's.
Ah cheers dude, much appreciated!i have a real soft spot for this era of alfa's.
This popped up on my feed today made me think of yours !
I have a dcoe inlet manifold I picked up cheap for my fury project but didn't work out. maybe its of some use to you ? The rubbers are in pretty good nick.
Managed to get a few little bits off the list yesterday. I swapped the little gaskets/washers on the cam cover bolts. My car had leather gaskets on all the bolts, but from factory the front four bolts have leather gaskets and the rear most bolts have a metal washer. Plus a couple of the bolts were weeping slightly, so they were due a change.
Old
New
I also made a start on cleaning up the engine bay. I have decided painting the engine bay with the engine in situe isn’t an option. The painting and masking side of things wouldn’t be impossible but the prep wouldn’t be doable, I think I’m just going to leave it until the engine comes out at some point in the future. Even though it’s no where near perfect a bit of cleaning and polish is making a big difference!

Also another parcel of Alfaholics bits arrived! Although the wrong radiator was sent by mistake, but the correct one should be arriving today. I did however find out there isn’t enough room for the 10” puller fan to go behind the radiator unfortunately, so I have ordered a spal 11” pusher fan instead to go in front of the radiator. It might not be as efficient as a pull fan behind but at least it will be hidden which is a bit of a bonus.

On the GT a puller fan needs to offset slightly to clear the end of the pulley. But they will fit.
I have seen rear fans, but I didn’t realise it was on the early radiators that it seems to work, as I think the radiator sits further forward? I have the bigger (later?) radiator which seems much tighter, definitely not enough room for the 10” fan even pushed fully to the left.Edited by MTW on Friday 1st December 09:04

Definitely can fit a 10" spal puller fan on later coupes if you offset it to one side so the saloon must have less room. At least with a pusher fan should you ever need to swap the water pump you'll no longer need to remove the fan.Edited by MTW on Friday 1st December 09:04

Ah ok, yes might be the saloon thing, or maybe even my car/rad. I’m only about 2mm away from it fitting. At the moment the fan is about a 2mm over the edge of the core whilst contacting the water pump, I have both fans still so I will give it another try with the new radiator. But yea I do like the idea of accessibility and looks with the pusher fan, the Caterham has a spal pusher fan on the front of the rad and it works really well.Some more good progress today. I thought I would get stuck in with the engine mounts. as they are right at the bottom of the engine bay, with the front grill and radiator removed the access is about as good as you will ever get.
First job was to drain the oil and remove the oil filter, as it obstructs two of the bolts in the drivers side engine mount holding it to the block.
No metal on the old magnetic sump plug which is always positive!
New plug and copper washer fitted.
With that done it was on to the engine mounts. I thought I would make a start with the easiest side first which is the passengers side. With the carburettor and inlet manifold out of the way access is pretty good.
Once the mount was removed I thought it would be a good idea to clean up as much as I could before the new mount goes back in. A quick spray with the degreaser has the block and crossmember looking a touch better.
Before
After
Got the new mount fitted up without too much of a struggle.
Then it was on to the drivers side which wasn’t as easy! Access is pretty bad with all three bolts which holt the mount to the block heavily obstructed by the exhaust manifold, I’m not sure how this job could ever be done with the radiator and grill in place! I had to go through the grill for the first bolt, through the top of the exhaust manifold for the second, then get to the third from under the car. using a combination of stepped spanner’s and wobble bolts I eventually managed to free the old mount and gave the area a clean up.
New mount fitted.
With both mounts fitted I removed the jack from under the sump, re tightened all the bolts once more and called it done!
In other news, the inlet manifold and front grills arrived back from vapour blasting and turned out fantastic.
Grills blasted and powder coated.
I dug out all the new hardware for the inlet manifold and got it all fitted up, looks spot on!
That was it for today. plans for tomorrow are to assemble the carb mounts and fit them to the inlet manifold along with the throttle linkage, fit new inlet studs to the block, work out the new cooling pipes needed for the manifold as the routing will now be slightly different, fit the fuel pressure regulator and lastly make a start on clearing the grot traps in the front bumper and give any rusty areas a coat of rust converter.

I managed to get another few hours in the garage this afternoon so I made dent in the ever growing list of jobs!
First up was finishing off cleaning the engine bay. It really is the meaning of “polishing a turd”, the paint in the bay isn’t in the best shape. But still, it’s a marked improvement. Instead of 50 years of grime and rubbish paint, it’s now just. Rubbish paint.
Before
After
With the engine bay as clean as it’s ever going to be, I moved on to a bit of rust converting. The product I’m using is Bilt Hamber Hydrate 80, I regularly use Bilt Hamber detailing products so I thought I would give their rust converter a try. Its a bright blue on application but it drys semi-clear and turns any rust black, most of the areas I’ve used it on are well out of sight so it shouldn’t look too bad, plus you can paint over it once it’s dry.
The first area was the battery tray. The battery sits on a plastic base, and it looks like some
moisture has made its way underneath and has been doing its dastardly work, resulting in a bit of surface rust.
Then on to the back side of the bumper and front crossmember. This area was a real grot trap, it was filled with all sorts of crud and muck so I’m glad to have found it and at least stabilised the surface rust.
And a little reminder of how it looked before!
I decided whilst the front of the car was up
In the air I would address a few areas of surface rust on the underside.
The car has been under sealed so it’s not in bad shape, but there is a few areas I have spotted whilst working on the car before that were missed by the underseal.
With that all done and drying nicely, I thought I would move on to building up the lovely CNC machined solid carb mounts, so I can get them fitted up to the inlet manifold along with the throttle linkage, that way the manifold is all togeather and ready to fit up.
All fitted up to the inlet manifold along with the lovely CNC machined Alfaholics throttle linkage. If only the whole car looked as good as this! Very much looking forward to getting this fitted up and the twin carbs on!
The last job for today was fitting the adjustable fuel pressure regulator. The fuel pressure regulator is an OEM ‘filter king’ that I have rebuilt. It features on most of the ‘super’ giulia’s that came with twin carbs from the factory.
With my car being a TI rather than a Super, it didn’t come with an adjustable fuel pressure regulator nor the little chassis mounting point required to fit it.
Luckily the ‘new’ reproduction version of this filter comes with a universal type mount, so I bought one of those and with a little bit of gentle persuasion with a vice and rubber mallet I shaped the mount to fit on the chassis rail in the same area as the OEM mount.
Hopefully at some point in the future the engine might come out, so the engine bay can be painted and the mount welded in and painted along with it. But for now it works!
And that’s as far as I got today, still
Plenty to get on with. But getting close to mounting up the twin carbs now which is exciting! Next things on the list rough order are, fitting new oil filter, fitting new inlet studs to the heads, fitting the inlet manifold, creating new coolant pipes and fitting new throttle linkage rods.
Lots still to do, but making good progress!

A couple of nice little bits arrived in the post this morning. A replacement model plate for the engine bay, and a OEM lubricant sticker for under the bonnet, which was missing from my car.
I will be keeping the original model
Plate safe just in case car has any sort of restoration in the future, and has an immaculate engine bay, I think the old weathered plate would look fantastic. but for now a nice new one does well to brighten things up a little.

Made some good progress on the Giulia yesterday.
First job on the list was to clean up the old gasket material from the mating surface between the head and inlet, and fit new inlet studs.
When I removed the old inlet manifold it was held on with a mixture of studs and bolts, which isn’t OEM spec. With the block and head both being aluminium, studs are the order of the day for anything being attached to either of them.
The new studs didn’t come with the really handy hex point at the end, which should be mandatory for any studs in my opinion! So fitting took a little while using the old two bolt trick. The first stud didn’t really want to wind in fully so I ran a tap up all the holes and that made installation much smoother.
The studs look mismatched only because different parts of the inlet manifold require different length studs!
All bolts installed and gasket surface all clean and ready to go.
Gasket went on next. I did use a little RTV silicone sealant around all the coolant and intake ports just to be on the safe side. There was some slight pitting around one of the coolant ports that might have caused an issue with just a dry gasket, so hopefully the sealant will deal with that.
Before going ahead and fitting the intake manifold I thought I would check the carbs actually fit. There is some play in the holes for the solid carb mounts, and once the intake manifold is on, the carb mount bolts are inaccessible. You really don’t want to mount up the inlet then find the carbs don’t fit!
Mine needed a fair amount of adjustment. I loosened off all the carb mount bolts, fitted up the carbs and then retightened trying not to move the mounts at all.
Next up was fitting the inlet manifold up to the head.
with the inlet all torqued up, I re-checked that the carbs still fit up ok. It’s nice to finally get them on the car! Even if it’s only for a test fit.
With the inlet done it was on to the coolant pipes. The coolant system with this inlet manifold is routed completely differently to the old one. so new coolant pipes are required from the coolant inlet and outlet from the manifold to the heater and back to the water pump.
A nice touch I recently discovered thanks to one of Titus Rowlandson’s latest builds, is the use of period correct OEM Romablok hoseclamps. They look so much smarter than using random jubilee clips in my opinion. So I have used those throughout.
With the coolant pipes wrapped up, I had just enough time for another quick job. With the oil filter and cartridge fitted back up a few days ago, I could re fill the oil. Probably best to get that done sooner rather than later, before I get carried away and completely forget!
And that was it for yesterday, it feels good to actually get the carbs on the car even if it’s just for a test fit! The next bits on the list are, wiring up for the electric fan, fitting the new radiator with fan, plumbing in he rest of the cooling system, fitting a new choke cable and a couple of other odds and ends that need to be done before the carbs can be fitted for the last time.
