Crankcase ventilation hose plastic bit for a 1.7

[MJ]

I need one of these

A picture paints a thousand words, so here we go.


There’s a rubber hose that runs from the oil separator, round the back of the engine under the distributor cap to a junction with two other pipes. At this junction there’s an L shaped plastic connector piece which pushes into the aforementioned hose, and connects to a junction piece. The red circle shows the relevant area.

Anyone have a spare one of these, as mines split and keeps disconnecting? (See the red arrow.) I could bodge it together with a cable tie and some duck tape, but a non-split part would be better.

If the same person also had one of the blue clip thingies (shown by the blue arrow) I wouldn’t mind that as well, as mine now only has one leg

Do you want the t piece or the hose MJ? Dealers still have the hose in stock (14ish quid), t piece however is long gone, I snapped mine a fortnight ago, so its currently held together with plastic epoxy.

Can't remember if I used the hose in the end, I'll look on the shelf tomorrow.

Around about what size is the connector there? Just wondering as I've used some of the black poly pipe connectors and clips for other vehicles bits and pieces in the past...you don't get much variety on sizes is the only draw-back. Maybe a trip to your local garden centre/hardware store would help?

I obviously didn't explain very well - neither Chris

In the end of the rubber hose, there's an L shape connector that's pushed into it. It's this L piece that's broken. It then connects to something else (which I think is the T piece your referring to.)

If you look at the bottom pic, you can see the rubber hose (under the blue arrow), and the L shaped piece is the bit you can see into the top of (as it's disconnected in that photo)

Garden centre may be a good idea Figgy, thanks. It'd probably be alright with some super glue and duck tape, but I thought I'd just see if anyone had any original Volvo bits - for originality

Right, ok... lets try this another way, I'm still not sure which bit you mean!

The crank case hose has 3 ends, block oil separator (the coke can looking thing) the carb base, and the air filter.

So:

Coke can -> L shaped bit -> Hose that goes under dizzy -> 3dimensional 14mmish internal x2, 6mm internal x1 t piece.

Carb base -> hose -> possibly to tpiece for econ -> hose -> restrictor (should be built into hose for all but '91 cars (if you replace this hose, you can get this 1991 restrictor still) -> hose -> 3d tpiece

Air filter -> Hose -> 3d tpiece.

Looking at that, do you mean the L piece from hose to oil separator? If so, finding that cracked is what lead me to change everything else, and break the other t piece in the process. No, not availible, I've got a 5/8" elbow from my local hose shoppe, and jubileed it to the oil sep, straight connector to the orig hose.

think i've got them bits on a spare 1.7 i have laying around hole engine is for sale if your interested going for peanuts pm me if your interested

[MJ]

Ah ha! I see what happened here - thanks Chris

The hose under the distributor and the L shaped bit were the wrong way round, with the L shaped bit connected to the T piece and the hose connected directly onto the oil separator. No wonder it kept coming off! They do fit fine either way round though!

I took the hose off a week ago or so to look into the problem, and I'm 95% sure that I put it back on the same way round as I found it. I've found a photo from 2 years ago, in which you can see the L shaped part on the right end, so I guess it must have been re-fitted wrongly by a mechanic. Would they check these hoses aren't blocked in a service? Maybe it was taken off to get at the distributor better, but I don't think anything has been done to that for a year or so - maybe I just didn't notice it.

I expect the L shaped bit cracked due to the stresses on it from being connected wrongly.

Lee - I would be interested in the L shaped bit and the blue clip if you'd sell them - I don't need a whole engine though PM sent
