    Very cool. Looks like a lotta 1984 QV engines.

    Out of curiosity I searched Google Images on "Alamy Ferrari Factory". All kinds of random stuff popped up, including other 308 photos I had never seen, such as …

    I think those are UFI brand labeled oil filters (whereas, the ones UFI makes for F are white). Like this example:

    Great pic of the engines!

    All noticed half of those engines has the silver aluminum body fuel distributor and the other half has the iron steel black fuel distributor.

    Silver = K-Jet without Lambda = euro version and 1983 US version
    Black = K-Jet with Lambda = 1984-85 US version

    Steve, no lambda means no frequency valve either?

    Thank you Steve! Wonder if there’s any internal difference between the silver and the black FD

    Yes - the black fuel distributor has the internal plumbing and external porting to allow the frequency valve to change the lower chamber pressure (and change the amount fuel delivered for the same plunger position - in a relatively fast way); the silver fuel distributor does not (and can only change the amount of fuel delivered by changing the control pressure to move the plunger - which is a much slower response). When euro cars with the silver FD are "US federalized" to be "with Lambda", they add a frequency valve and the electronics to change the control pressure, but it's far inferior to how the black FD works.

    Although it can't maintain Lambda to the same degree the ones with a frequency valve can, I have always been impressed by the elegant simplicity of the original basic K-Jetronic system.

    K-Jet without Lambda was/is brilliant as being far, far better than a carburettor and not using any electronics at all (just some constant +12V heaters). It's only downside is having a complex thermo-mechanical gizmo (the WUR).

    K-Jet with Lambda has the downside of adding electronics and the frequency valve (to give the fast Lambda response), and still has the thermo-mechanical WUR (doing a slow response for cold vs warm running). Since the frequency valve and the WUR are doing the same sort of thing, it's a bit overly complex so they evolved to...

    KE-Jet, both with and without Lambda, replaces the WUR and frequency valve with a single Electro-Hydraulic-Actuator so only electronics, no thermo-mechanics.

    I identify with fourth row second from top, so therefore IT IS the engine that came in my Euro QV. That's my story and if you don't like it, you're quattrovalvolephobic!

    Same with me here. A few carb drysump engines while the 2V-i already existed:

    Slightly off topic but the previous post about "what the blue oil filters" were just made a dumb question pop into my head.... Been an owner of several models since 2000, but not sure I've ever heard or known the reason/advantage for the inverted oil filter design/placement that Ferrari has used almost forever?

    I am no expert, but it seems like it was just a convenient place to put the filter. I doubt there is any technical advantage.

    It's nice that the filter is so easily accessed and that everything stays nice and clean during removal. One still has to crawl under the car to drain the oil though (aside from vacuuming it up the dipstick tube).

    I suppose it is quite eye-catching to many car people: I've grown totally accustomed to it. Actually, I kinda like it there.

    To be honest, of all the cars and trucks I’ve owned through the years it’s the ones with oil filters mounted sideways that make the most mess. What were they thinking?

    +308

    Cleaning the surroundings between the cylinder-V and the mess down the bellhousing, etc., though using a lot of paper towels to protect, is the most time consuming job during a 308 oil change. And this is on a drysump car, where I have to remove two drain plugs.
    At least for me.
    But I have experienced, when waiting a few hours after shut down of the engine before removal of the oil filter, the mess is significantly less because most of the oil could drain down the sump and we just have the amount of oil left in the filter, which is retained by the standpipe.

    Is that the UFI filter like the one Steve posted on post#4 above?
