W8 Passat Engine Teardown and Inspection ~ TINY V8

  • Today we tear down a VW W8 engine. The W8 engine is 2 VR4 engines in a V. Similar to the W12, Turbo W12 and W16 engines. While we dont get a W8 straight piped, we do completely take the W8 apart and check out the heads, timing chains, block and pistons. The W8 Passat was the highest level Passat you could buy. Also thank you to WD-40 Brand for partnering with us on the video.

      Nah, this is their Bentley/Audi Engine. It's not meant originally for a Passat. At least not in Europe, VW just keeps telling themselves (especially back then) that in the USA everybody wants a huge engine. Which is really not the case. People want reliable easy to maintain engines, and that you get from a reputation you build over the years. Had they done that, most wouldn't have been harping about how unreliable VWs are :(. It is really VAG's and VW USA's own fault.

      They make really cool engines, just not the most reliable or at least not the easiest to work on. At the end of the day not every engine design is gonna be a winner when you're doing your own thing like VW instead of playing it safe like most manufacturers. Just ask Mazda about that one as well with their rotaries.

      @buffuniballer 3 роки тому +5

      I believe some of the 90 degree GM V6 engines used similar rod journals to make the engines an even fire arrangement. Otherwise, they were odd fire where you would have some cylinders firing after 135 degrees and others after 105 degrees. It averages out to 120 degrees between each firing event, but it wasn't smooth power delivery.
      So this isn't new. VW just added an extra level of complexity with their design of other parts of the engine.

Off the line was a bit slow given the power but as I understand it that's because the transmission wouldn't hold the power, so they limited power in first gear.

    I love how this is seemingly a super complex engine when you think about a W8 at first. I for one, could never picture how the crank would be laid out for a W motor like this until you broke it down. In typical VAG fashion, what is seemingly super complex is really just an elegantly simple solution: rod bearing journals which are slightly offset and a slanted piston top.

    The super fine mesh on the (broken) screens for the cam adjusters are a common failure point: they clog up with the tiniest amount of sludge buildup. The broken screens probably saved the engine. Other major failure point is the lock up torque converter as VW used the v6 transaxle which wasn’t up to the torque.

    @humblemechanic: in the video you asked whether there's some fancy coating on the valves. No, there's not, it is made from Alusil (hypereutectic aluminium alloy) and a special honing process of the walls form hard silicon crystals on their surface, so the pistons (made from the same alloy) slide directly on the aluminum wall (on a oil film of course :) ).
    Regarding the belt, it is a comon failure on these engines. It has to be replaced let's say every 80-100k miles (together with the tensioner and the wheel you found jammed), but nobody does this.....voilà :) I am also adding that last year somebody in the US bought off the very last one of this little belt in the whole world...
    We at the W8 forum also discussed whether the balancing shafts help to distribute oil, hence upon this failure the engine dies slowly (jamms at the first valve and spins the main bearing)...
    Cheers from the CZ! ;)
