I've never been a fan of Strombergs - a Triumph-inspired, less reliable version of SUs in my opinion.
A good condition SU is a fine piece of kit but American carbs work well on American engines
Wholeheartedly agree Richard, the Stromberg is an over-complicated animal to start with compared to the SU (Simple Uncomplicated - i know it should be Skinners Union but that works for me too) but compounded by the auto-choke that was on Marcs (FASD or was that SU only, can't remember now) and generally too prone to failure and wear.

Out of all the V8s i ran (5 in total) i only had one with a pair of Strombergs (manual choke) and it soon became apparent they were faulty - 18mpg at best on a good day was a big clue! All the other V8s i used to get 28mpg from and after i replaced the Strombergs with SUs i once again got 28mpg from it.

As you rightly point out, USA carbs work the best on USA engines, i just hope i haven't given Marc any ideas with that Wiki article - it mentions the Oldsmobile Cutlass Turbo that used the same engine............. :P :wink: :D
Cheers,
Dave

Thanks for the info as always Dave!!

I understand wat you mean Richard. I talked to a specialist what he would do and he even did not want to rebuild the Strombergs. Het was willing to install SU carbs because they are more reliable but then i would need a hand choke and that would mean that my interior would have to come apart again. Not an option.
We use this old brute like it is supposed to. Driven and enjoyed around the continent and therefor reliability is number one priority.:)

A while ago i wanted to clean and check the bottom side of my Rover Vanden Plas. I asked my boss if i could use the lifts and that was no problem! :) First i sprayed a cleaner on the underside and then hosed of everything. It was not very dirty but the loose stuff was gone.
Image
Image

Of course one hopes not to find rust but i did came across some areas that needed attention. At first i was a bit shocked but then i understood that a 38 year old car always has rust, especially an SD1.
This was the floor on the right side. The left side was almost as bad. On a few places it rusted all the way but the main area was the circle. It looks worse than it was because of the rusty moist that got in and left its colour around the car. Besides the rotted circle there were some holes that i welded shut with a plate or with the welder.
Image
I cut out the circle bigger and made a new circle of fresh steel.
Image
This circle was welded from the bottom. Because fire is a hungry and fast ellement i covered the interior to be sure no fires could start. Also a mate was present so that he could help with pressurized air or a fire hose.
Image
After this is applied a rust preventive primer and sealed the seems with sealent.
Right side:
Image
Left side:
Image
Additional primer so i could apply colour:
Image
Coloured and old plugs re-installed. Every thing was cleaned after all the work.
Image
Because i had to remove the old sound deadening i installend new one:
Image
Image
Bottom side of the welded circles with rust preventive primer and sealer:
Image
Next place was the left rear wheel arch. The edge behind the wheel spat was completely rusted away. I had to make all the parts new.
Image
Image
From the left rear wheel well you could see the inside of the boot.... Not good! Behind the towing eye rust formed.
Image
First i cut open the steel from the boot. After i cleaned the steel properly i applied zink coating on the inside of the outside plate.
Image
After this, i welded a plate and applied rust preventive primer:
Image
After this again used sealer to make sure everything is sealed.
Then i welded a small plate on the outside and coated everything with body coating:
Image
The right, rear wheel well was not as bad as the left one. Wheel edge was fine so only had to weld a plate at the back of the wheel well.
Image
Just as on the left side, rust formed behind the towing eye. Not as big as on the left side but still enough to cut open the steel and clean it properly and apply zink primer:
Image
Image
Making new pannels!
Image
Everything welded up and ready for rust preventive primer:
Image
Image
After this also sealed everything with sealer.
In the left front wheel well there was a mean spot that took some Macgyvering. It all worked and it was welded shut with fresh steel again. Primed, sealed and stone chip body spray applied.
Image
In the right sill there was a weak area that i cut open and welded a new section in. After this re-coated bot sills and painted them.
Image
The old boy looked like this during the last weekends:
Image
Today i removed surface rust from the wheel arches and coated them with rust preventive primer and paint
Image
Looks quite good don't you think?:
Image

All that is left are some details and ad rust preventive wax. Cherry on the cake as you would say it. ;)

There was a lot of rust, but you treated it really well.

Congratulations on a very good job

Great work there Marc! Surprisingly rust-free for an SD1 although i think the 1980/81 onwards models had better corrosion protection.

Should be solid for years to come now! :wink: :D
Cheers,
Dave

@ Lodein: thank very much! 😃

@ Dave: Cheers! Yes i agree, not bad for such an old car. Ah that could be. I think the quality of the cars was improved during production.

@ 820Vitesse: Thanks!!

I think the SD1 work that was started surrounding the rust is now completed. :)

Boot first sealed with sealer and then primer so that i could apply colour:
Image
Image
Image
Then i sprayed cavity clear was in the seems to prevent moisture to form.
Boot done!
I applied an extra coat of 2K clear coat allong the wheel arches:
Image
They are more shiny now than the rest of the body :P :
Image
Image
To tackle the wheel arches i had to remove the old mud flaps. By doing so i broke of the threads. I ordered new (old stock) mudflaps. To prevent rust from forming on the brackets i coated them with 2K clear coat as well.
Image
Image
Then i applied cavity wax to the underside of the car and coated the exhaust:
Image
Now i took a picture of the end result of the cirkels that i welded in:
Image
Image
Cleaned the last part of the sill seem that was covered by the lift all the time:

Your Rover SD1 will be better than new, but I heard that is not difficult because the quality of the SD1 was bad !!!

Congratulations on this good job
