Opel OHV

Hello, Do you use this talk/discussion page? If so I would like to discuss Opel OHV engines as related to their cousins used in the USA. Thanks,Toneron2 (talk) 07:07, 16 January 2010 (UTC)

1983 Chevrolet Cavalier Engine 1 1983 Chevrolet Cavalier Engine 2

Can't seem to find pictures of 1983 Vauxhall Nova or Opel Kadett engines... Toneron2 (talk) 07:42, 16 January 2010 (UTC)

• I am not completely sure, I am not working at GM Powertrain. But there are two reasons that the engines are not related: (1) is size, (2) is time.

Size: The Opel Kadett engine started with 1000 cc and grew up to 1200 cc. That was the end. The GM 122 engine started with 1800 cc in the 1981 Chevrolet Cavalier and grew to 2200 cc. This is almost twice the displacement of the Kadett engine.

Time: The Kadett engine started in 1962 in the Opel Kadett A and was continued in Kadett B (1965) and Kadett C (1973). In 1979, the all new Kadett D had front wheel drive and a completely new OHC engine. As far as I know, this was the start of the GM Family 1 engine. The older OHV engine was continued as a basic engine for Kadett D, Kadett E (1984) and Opel Corsa A (1982). 1993 the Corsa B was introduced, that was the end of the old engine. The Chevrolet Cavalier and its mates (Pontiac J 2000, Oldsmobile Firenza...) started in 1981. It is not very probable that they received the 20 year old Opel Kadett engine.

The European mates of the Chevrolet Cavalier were the front wheel drive Opel Ascona C and Vaushall Cavalier Mk 2. They received the modern OHC engine, starting with displacements of 1300 and 1600 cc. Later, larger engines with 1800 and 2000 cc were added, they were part of the GM family 2. Ironically, the sportier versions of the American cars (Pontiac and Oldsmobile) also received the OHC family 2 engine.

But the OHV engine of the Chevrolet Cavalier, is it related to any European Opel or Vauxhall engine? I don't know. OnkelFordTaunus (talk) 20:30, 16 January 2010 (UTC)

Thank you. It was an incorrect assumption on my part that when the OHC engine replaced the OHV engine sometime during the Kadett C and Ascona C run that it was an evolution of the design. Do you know when the OHC engine appeared? Toneron2 (talk) 19:46, 17 January 2010 (UTC)

• Yes. It first appeared in February 1979 in the Opel Ascona B (a car with RWD!) where it replaced the 1200 cc OHV engine. The reason was that the 1200 cc engine was good in the Kadett, but too weak for the bigger and heavier Ascona. Then, in August 1979, the all new Kadett D was introduced. It was a major change, because Opel had to answer to the good selling Volkswagen Golf. So, the Kadett D got a modern hatchback body, front wheel drive and the new OHC engine (the older 1200 cc OHV engine was also available in the Kadett D for price reasons). In Britain, the Kadett D was rebadged as Vauxhall Astra where it replaced the Vauxhall Viva.

Check the articles of Opel Ascona, Opel Kadett and Vauxhall Astra, they all offer informations about the introduction of the new OHC engine. And, as far as I know, the informations are correct. OnkelFordTaunus (talk) 21:10, 17 January 2010 (UTC)

• Great information! My understanding was the GM Family II started in 1979 - however in re-reading the articles, there appears to be a larger OHC engine available in the previous generation of both vehicles. Was this another engine altogether?

In the Ascona A: "The 1.2 L had an overhead valve(OHV) head, while the 1.6 L and 1.9 L featured a camshaft in head (CIH) type of engine." - if CIH = Cam In Head aka OHC.

Also in the Kadett C: "...Rallye and GT/E models. These models were built first with the Bosch fuel injected 1897 cc OHC (over-head cam) Opel engine, and followed by the updated 1998 cc OHC engine."

Also the Ascona B timeline shows new 2.0 L engines being introduced in 1977 and 1978 and also in 1979 a 2.4 L DOHC! Do you know any more history about all these engines? Thanks again for your time I find this useful - and hope to research further for the articles. Toneron2 (talk) 07:33, 18 January 2010 (UTC)

More info here - looks like an entirely different engine altogether!Toneron2 (talk) 08:22, 18 January 2010 (UTC)

• The information in the link (customs-n-classics.dk) is correct. This was an older engine usually called the Opel CIH engine. I added it to the List of GM engines but it is still red colour because I did not have the time yet to write an article. So just some basic informations:

The engine was introduced in late 1965 in the Opel Rekord B were it replaced the venerable Opel Olympia engine, a prewar design first used in the Opel Olympia 1938. It was the "bread and butter" engine for the Opel Rekord series B, C, D and E until 1986, but it was also used for Opel Ascona A and B, Opel Manta A and B and even - as a luxury big displacement engine - in Opel Kadett B and C.

It started in the Rekord B in three displacements: 1500 cc, 1700 cc and 1900 cc. Later, there were versions of 1600 cc (1970, starting in Ascona A), 2000 cc (1975, starting in Rekord D), 2200 cc (1984, Opel Rekord E2) and even 2400 cc for Opel Omega A and Opel Frontera.

The 2400 cc rally engine is a special engine for Opel Manta 400 and Ascona 400. It was heavily reworked, but it was based on the CIH engine.

Starting with the Ascona C in 1981, the CIH engine was slowly phased out and replaced by the OHC engine we were talking of at the beginning. For more than ten years, both engines were produced side by side, but the CIH engine was reduced to its larger versions (2200 cc in 1984, 2400 cc in 1989).

• Excellent! I am looking forward to your article on the CIH engine. People in the US have no idea about the Opel engineering in the cars they drive. Toneron2 (talk) 19:00, 19 January 2010 (UTC)
