  1. These were good cars. There are two probable failure areas.
    1, the oil feed pipes over the tappet covers, most of the V8 single overhead cam, had little plastic clips. These go brittle. I used to buy from the agents. Lift the tappet cover off, replace them. The plastic goes brittle.
    2, the timing gears. With the covers off, check condition of the teeth, especially the one in the V. For that you need a scope. (Snake camera) what happens over the years. The easy gears get replaced. Or just timing chain gets replaced. The tensioner only has an O ring, so it’s easy to replace. But the issue is when starting. That slight rattle. Should not be there. If you blip the throttle, it can jump one tooth on the gear in the V. Suddenly one bank will bend the valves.

  2. Wow…..Dennis & his crew do fantastic work. Ive seen DI blasting before, this one has me hooked. Keep up the great work, love the term, “sympathetic restoration”.

  3. Awesome video as always Dennis and the Coffee Walk team! Love watching everything you all do and like how you show how everything you do is done vs others that don’t and only show a portion of their life and business.

  4. I thought the car was already immaculate, the dry ice process expensive no doubt but the results are amazing 😮

    1. Dry Ice won’t remove the original bodyshutz (undercoating) only the layers of grease/road crud from the decades. Plus the pressure being used is rather light as opposed to what’s normally used …….

  5. The oval car plate is easy to explain. These plates were exclusively made for the German Customs (Z for Zoll; nowadays they are different). This meant there was no VAT to pay in Germany for the vehicle because you were obligued to export this piece within a certain time. German cars were allowed to be driven six months in the U.S. and than being taxed for U.S. VAT. If he still has the ovals may be the car was never imported regularly although prepared for the U.S.market. No wonder he had no U.S. title

    1. And I assume there was the option to have German documentation with the car and since Klaus was German he might’ve explicitly opted for that.

  6. My step father did this in 1989 with a 300D,
    Except he drove his in Germany around Europe for a certain amount of miles,
    Then shipped it back on a boat used, he “saved” some money???
    The boat people lost one of the 2 keys they gave them to move the car, so he kept it locked up in the garage, he thought it was a car smuggling ring, a little paranoid?
    Or not.❤ Love Denniss knowledge

    1. Back then there were people who worked on the ships who would either take one of the keys or make a copy of the key with a portable key-cutting machine, and write down the address the vehicle’s owner had on the paperwork, and once they unloaded the vehicles they sent the keys and addresses to a chop shop and the chop shop paid car thieves to go steal them, the guys on the ships and the car thieves would get paid so much per vehicle, the more expensive the vehicles were the more they would get paid. And at that time a lot of certain types of vehicles like the new Ford Bronco’s were being stolen here in the U.S. and put in shipping containers and onto ships and taken somewhere overseas. It was a major issue back in the 80s and into the 90s. So I take it your stepdad had been told about it.

  7. Well done to Steve for being the mediator Dennis . An of course no one does their homework better than you Dennis . And over here they were notorious for rust ! Thanks Dennis.

  8. When I was a quality engineer for the world’s largest earth moving equipment manufacturer we started using dry ice blasting for steel castings 20 years ago both to remove some toxic preservative coatings from the supplier foundries but also rust from improperly preserved castings being shipped oversea. The best thing about the process is there is nothing left over to dispose of beyond the dust of what was removed and that is huge when talking about possible hazardous material disposal with used blasting media. Steel and iron castings were also immediately ready for painting with no further prep because of the no residue process of dry ice blasting.

  9. That dry ice restoration is quite amazing. It looks like it brings everything back without damaging the Surface.

  10. This was a great window into the ultra high end restoration process. It is something even most car folks will never experience. You don’t need to reveal all your secrets but I hope you will have future episodes with similar content. Watching Alex wrench on a super car and talking about what he is doing would be fascinating. An expert doing body work and paint would be great. A whole episode of just the chrome process. An episode on sourcing parts, both new and old would be cool. I hope you will consider this for future episodes.
