Auto Italia Motorsport day has come again and somehow the GTV race cars are still a strong favourite in the main display area . Later on in the morning we took the cars over the road and did a few laps on the mercedes Benz test track . Was good fun to catch up and talk bollocks to all the usual suspects.
Richard Melvin and I catching up after a few laps on the track . Pity the Lambo in front was slowed down by the Merc health and safety officials as we were warming up for some good sprints !
Some pics to follow .

Update : car is running perfectly but as projects always evolve my next plan is to change the rear differential from the 13:47 ( 3.61 ratio) which I took from the Alfa sedan and replace it with the E36 M3 Diif .
If I had a high reving 3.2 motor I would probably leave this differential in but with my 3.7 which i tend to short shift at 5500rpm I'm going to copy my mates twin turbo set up and build a cage to house the M3 type 188 differential . ( 3.15 ratio )
I have investigated getting another crown and pinion made which is very difficult as it's an offest hypoid type with estimate cost of 3k so thought it would be much cheaper to make a simple bolt In conversion as in pics below .

Nice work Kevin, I've often wondered why people use the sei diff considering its weight when the Bmw option is easy to find many ratios and I'm sure would end up lighter if built well. Plus the serviceability and strength

To reply to wondering everyone use Sei diff .. Was it is very simple bolt in conversion with your brake set up all in position ... Also there were loads of Sei spares in South Africa .
Bmw spares then we're very very expensive especially when sourcing an M car for the LS while the Sei comes with one .

I had to close in my doors for MOT purposes as the don't like open doors even though all the webbing and bracing had been cut out . There was no possibility to get your arm stuck but anyway i just got a neat light solution using 1mm plastic , carbon wrap , some Audi plastic clips , door pull straps to close , heat gun and some time .

It's been six years since replaced cam belt which is well over its expiry date but also only done a few thousand miles so better late than never . Car has been in storage and a lot of parts need to be freshened up .. I unfortunately had a serious back injury five years ago which prevented me from using this car properly but I think its mended :) . Got some hill limbs still to do this year and it's always good to show off an Alfa engine bay in the paddock amongst the other brands .
So bonnet off and radiator out ... Unfortunately weak back lead me to pull radiator out skew and damage it ... So cross
Now must figure out way to sort it !

New belt on . No cam blocks , just had to loosen off one pulley to make sure intake was perfect on mark . Rotate engine few times recheck tension and all is good !

Hi Kevin,

It's very annoying when goof ups happen. Sympathise with you there. Cannot say I have done any aluminium welding myself so perhaps my idea isn't worth a cracker but if the problem is just one tube, welding it up as a complete blockage would not make any material difference to the radiator's performance. Check with a radiator Works.

The other off the cuff idea may be to bond it chemically with some form of resin and hold the adhesive together in a flat compression washer "sandwich" with a 4-5mm nut and bolt and a washer size of say 30-40mm diameter. If you lay the radiator horizontally while the resin is curing and the clamping washers is in place, the resin will flow around the break and bond with the washer as well. That will form a solid core in the area. The operating pressure of the cooling system isn't going to be an issue. However, the expansion and contraction of the heat cycle could be one eventually.

Others may have a better suggestion.. :calling all chemists?

Hi MD .
Good thing is it only one little hole so after reading your thread I found these two options on net ...
First is if I can get these rods then I can get a very skilled mate who can " solder " this up for me like in this link

Or I should give it ago with Devcon which we have in workshop . Not sure which is gonna be best bet ?

Oh .. Saw your race car in a video clip filmed from some very fast fast Alfa ( obviously in a higher class) breezing through the field . Must find it .

Cheers
