Monteverdi Sierra Register

I have compiled the following register for all Sierra's I have been able to find on the internet. Some VINs and photo/details are assumptions, meaning they don't necessary have to match and need to be switched around (once confirmed). Typical this adds up to 20 identified vehicles which is the estimate of the total Sierra's produced (allthough a firm number has never been confirmed). As can be seen this includes the two convertibles and one stationwagon. Note that the last Sierra in this register is dated from March 1980. By then the Dodge Aspen production stopped, so it's not very likely that any more Sierra's have been produced thereafter. If so then the production number is pretty much 20.

Well, according to this link http://classiccars.wikia.com/wiki/Monteverdi_Sierra it turns out that one of these 3 cars is actually very dark blue with a cream interior. And when checking this seems to be correct. So perhaps VIN 9155 might be the actual one.

Random engine bay checks and cleaning - matching numbers!

Previous time I sprayed the entire engine bay with WD40. I had done this to uplift the looks and as some kind of rust prevention. This is what it looks now

Compare that with the view when we just bought it:

Not a lot happened since. At the time Jos checked the basics and a lot of things were ok though. see these blogs:

Engine running free: http://monteverdisierra.blogspot.com/2018/04/moment-of-truth.html

I'm now eager to get the engine running again. So next time around I want to check if it sparks. And I want to clean the carburettor ultrasonic and give it a new service kit. If it sparks and the gas mixture is ok it should simply start. 

Another thing I already had checked was the color of the engine bay. I think by Dodge factory default it's in the same body color. See this example:

So Monteverdi simply resprayed the engine bay entirely black (by now after all those years the Original brown color is become visible again). I suspect for this activity they must have removed all parts in the engine bay. When doing further checking I noticed some items had missing screws or broken/damaged/replaced.

Missing screw, or is this mounted only with 1 screw and glued by factory default:

Broken screw on a radiator cover plate:

Missing screw, by the looks of it there has been one:

Another one missing, or factory default?

Air intake, different screws and one broken/missing:

Next I noticed some of the "vacuum hoses" had been topped off with screws. I suspect they must have experienced some issue's with it. It's a common fix/trick:

And wow, look at how this battery cable is extended via a huge crown stone:

I also noticed the window washer hose was sprayed brown. I figured that when the montverdi bonnet cover was created/fixed over the Original bonnet it of course had to be sprayed in the same Original  body color. So that explains how the black hose got brown. 

Last but not least I discovered something else, apart from the known VIN label:

It was also stamped on the chassis,  I discovered it when cleaning and removing the radiator cover:

So yes, we have matching numbers :-)

Bonnet air intake part II

http://monteverdisierra.blogspot.com/2019/01/monteverdi-sierra-bonnet-air-intake.html

I had already noticed the ridges on the Original BMW air intake counted 43 ridges in total. The Sierra intake however counts 64 in total. So I suspected they tailored two pieces together. On the Original Sierra leaflet I had noticed a slight difference in the mounting with a visible split in the middle:

And today it's saturday so I could have this checked. You can see the ridges in the middle are slightly closer to each other (click photo to enlarge):

So time to dismantle, and yes, it were two seperate parts:

And this is what it looks like whithout:

And the centre piece in detail, just some simple strips welded and parker screws to mount it:

The Original plastic air intake beneath was in a poor state as well:

I spend some more time on cleaning the engine bay. The paravan area (cowl) was very dirty and now with the air intake grilles off it was easy to blow out. Again a lot of walnuts came out of it.

I noticed some other small things which I will do some more checks and reporting on next week.
