I just bought a 82' Westfalia that needed an engine rebuild. The engine I bought it with was a 2.0L Fuel Injected Air Cooled engine that overheated, and after looking at it and getting a few second-opinions, it's gonna cost a lot to rebuild. I do have an alternative though where I can get an engine from a 77' Westy, Air cooled, fuel injected, 2.0 liter, but I just want to make sure that everything will fit and work with the 82' before I buy it. Do both engines have all the same specs where it will fit right in? Anyone have any other advice for me? I just want to get my new van running so I can enjoy what Westfalia's have to offer! Thanks.
