1986 240 Some name for this hose? goes to flame trap, picture 200

I need to clean the flame trap on my 1986 240.

The flame trap is easy to buy. I want to replace this hose during the process, and I don't know the name of the part to order. This sort of thing tends to split when I remove it. Old car.

Here is a picture

    Hi Mkoch,

    I'm sorry, to me the hose in the photo looks like it is located at the middle of inlet manifold. Thats the curved hose leading to the idle control valve (ICV). For B230 engine the part number should be 3517084.

    Regards,
    Amarin.

      Closer yet, but no cigar. 200 1986

      You are absolutely correct; the hose being pointed to is not part of the PCV plumbing, or flame trap.

      I'm sorry, but it seems we are not getting there even now. This car's B230F has different hoses from the 89-93 B230F equipped with LH2.4 using the 3517084 hose you've identified.

      This car is equipped with LH2.2, using the three-terminal idle valve with a hose like 1336080 (NLA)



      The differences are shown here, with the older LH2.2 system on the left and the LH2.4 idle circuit on the right:

        Hi Art,

        I looking into picking up a 1993 sedan soon.
        How can you tell if you are looking at a 3.1 system on a 1993 instead of the 2.4 system?
        Are there other details to look for?

        Is it only the throttle switch, that does not click, due to it being a rheostat Type?

        I think the flame trap of a 2.4 setup stays the same throughout 89-93.

        I’m not sure I want a 3.1 due to the rarity of JY parts.

        Thanks
        Phil

          LH3.1 200

          Phil,

          I think LH3.1 was not available on '93 240s. Perhaps not even in '92. Hope someone else will chime in here and correct my memory, but my understanding is LH3.1 was used only on M47-equipped 240s in 1990 and 1991. You can most easily recognize it by the air mass meter's plug which only has four terminal connections.

          My opinion is it isn't a "newer, better" LH like the higher version number would imply, but a transition toward the less expensive hot film air mass technology used in the FWD 850 series cars beginning in '93, made necessary by emissions requirements. I also would avoid it for the reasons you cite.

            LH3.1 200

            Thanks Art!

            You very well maybe right on all points you speak of.

            I have not seen any of those AMM’s with a shorter width or length connectors, for the number of less pins I presume, on my crusades through Junk Yard’s.
            850’ are rare or I walk around with blind eyes to them. Those as FWD’s scare me on how anybody can get their hands and tools in there. Even with parts of the car missing to give you access the FWD concept is gruesome.
            They remind me of the change over, with fuses and their console location, that happened to the 700 and later series.

            I still appreciate simplicity and it’s the only reason I look twice and do some work on my sister-in-laws 1973 VW Bug.
            Their fuses are in the center and below the dash where you can kick them. Maybe that’s over the top too simple?

            She is finally waking up to the fact that she has put too much money into now. Paint job and engine. Now the engine has one cylinder with excessive blow by. So much that she is getting oil on the inside of her windshield! Heated air goes up there for defrost ... air cooled engines!
            Her young man mechanic who put in new engine in, tricked it out with chrome. The kid also did away with the original air filter box in favor of a tiny round thing.
            Things seemed fine for awhile.

            About a year ago some mechanic “soaked her” for a breather box for the crankcase.
            I thought the breather box was a bad idea and talked her into replacing the original VW air filter box complete with the original crankcase hose. But it’s still not enough to suck it back to burn it.
            I kiddingly suggest to her buy a box of Depends and wire tie one on to that breather box.

            My wife then got the idea that “we” should look for a Volvo for her to buy. The ploy was I could keep it running good for her. Like I don’t have five already.
            She went surfing and talking to her sister but the sister is low on funds but my wife kept surfing anyway. Her sister has held onto her bug since high school but getting ripped off has put sour grapes in her mouth.

            So, long story short, the only “looking” got the new car bug going in me again. I’m one sick puppy!
            Taking aspirins and going to bed only works with buying the newest car fevers!
            Old cars are too cheap to trigger the immune system, I think!

            There are some interesting deals around. I don’t know if I want another wagon or more sedans. The sedans seem to be better taking care of, newer and more plentiful. Wagons are getting hobbled together, especially the mid eighties ones and up.
            They have the more knock-less prone piston engines like my 1986. Money is about the same until the nice 90’s sedans for $500-$1000 more with less blemishes are all around. I try to stay away from clear coats as they are just trouble on the way! They cloud and then peel.

            Anyway thanks helping to take away that concern on the 3.1.
            I will still lift the TPS just to be safe.
            In about a week, I will be zeroed in on one. Translated .... poorer!
            (:-)
            When I croak maybe everyone in our family will get a Volvo, as I have no kids and No, We are not looking into adopting any Brickboarder’s, as of yet!

              LH3.1 200

              Phil, the parallels keep making an appearance. Last time we hijacked a thread to which the OP never returned, we discovered the 3&3 in-law connection.

              Well one of my 3 (sister in law) drove her brand new 73 bug across country stopping to visit us on her way to CA. I got to drive it briefly -- one of only 2x behind the wheel of a VW for me. Almost as fun as a bike, but with more passengers, I remember. But the parallels diverge, as she only kept it for a few years.

              Back to the 3.1 identification: If the car was relatively new and clean, I'd trust hearing that click on any LH2.4-fueled motor, but if not so clean, I'd not immediately conclude it had a potentiometer throttle sensor. Too many are full of oil or misadjusted to feel the click distinctly, especially amid the noise of buyer checkout emotions.

              But have one look at that LH3.1 AMM, and I'm sure you'll see a stranger.

              Edit: Also, had a look at the Bentley just now. According to the VIN decoder, the 88 in positions six and seven indicate it is NOT an LH3.1, and 82 is there if it IS an lh3.1 engine.

    wow. that is a lot of oil. the rear seal on the cam shaft may be blown or is getting a lot of blow-by. something is clogged in the crankcase ventilation system as was suggested in the other posts

    Hi: I can't get your picture to come up, but get on e-euro site and look at their pictures. N.B. I'm in Indy and trying to buy some parts and the guy wants to sell me a complete but non running 89 740 sedan TURBO AND 5 SPEED. $500?

    If that is what you need it is called the flame trap hose.

    That is a lot of oil being blown out over your engine. Do you think the rubber gasket on the oil filler cap is where it is getting by? You should replace that as well.

    If the oil separator is restricted cleaning the flame trap is only part of making sure you eliminate a crankcase pressure problem. The crap you find in the flame trap can build up in the separator as well. Check the separator by removing the oil filler cap and blowing through a length of hose you attach to where the flame trap hose connects. You should be able to easily blow through that hose to insure the separator is not restricted.

    The nipple on the flame trap holder must be open as well as the brass nipple on the intake that the small diameter hose connects to.
