1.6HDi/TDCi oil catch can started to collect oil, Update #2 (Peugeot/Citroen/Ford/Volvo)
4 Comments


So this is my 2007 1.6 HDi Peugeot
Partner engine and this is another update of my oil catch can installation
and since I installed steal scourers and the weather has turned a bit warm it’s
started to collect oil so I wanted to slacken, dismantle a few parts just to
show if oil is coming up in what what’s going on with the whole system and what
I’m thinking to additionally upgrade this whole system so first to have a
look at what’s inside the oil catch can, so if you are really interested in how this
was done check out my previous videos so first to see what is the condition
of the oil catch can. One thing to notice there are several spots here and there from
oily bits and pieces but on the sides in between where the valve opens
so there is not really no oil parts in there so which means that this valve
hasn’t been opened, in other words the pressure hasn’t been high enough I think
this is 50 millibars so it has not opened which is actually quite good so he
hasn’t released this. Next is the oil catch can I mean so I put the steel scourers
inside and the whole thing is it’s fairly oily so oil comes up to
the oil catch can and if you can see there is a lot of oily spots around at
the bottom where and the oil has to coalesce and drop down so inside it is really, really oily so it kind of the camera is too bright but kind of
collects quite a bit of oil so down at bottom there is
quite a bit of yellowish and so on fluids so the next thing is to really
if I put my finger here in the input so oil comes up quite a bit, so I know it has collected oil, so I’m not really sure if the oil
that has been collected is from the
scourers so because the weather became pretty warmer much warmer now, so it
it doesn’t really condense that much moisture but it condense more oil so
I’ll put the camera down inside where the exit is just to show you that there is a
that much layer of oil there. There is a pretty substantial layer of oil above
the water so there is water kind of underneath the house so below
and above there is a really a substantial layer of oil so it
has been collecting oil so now draining it I have hidden the hose kind
of underneath this plastic and empty jar I have to cut this before This is my kind of safety
valve, this is if this is somewhat opened, it would not leak with a bit of a hose inside. I’ll now open it to see what really has been collected perhaps
move the camera slightly. Let’s see. There will be quite a bit of water but there will be
oil as well oh yeah there is a slight oil that came
down not too much so I’ll let it drip till it’s finished
so this is really the the fluid from the from the oil catch can. So I’ll open this so I
mean it cannot be seen but that’s the that’s a really thick oily part
otherwise um it’s very sticky I mean the way I see it, it is very sticky I
mean you can see how it sticks it doesn’t doesn’t really move so it has
collected not too bad some some proportion of oil and quite a bit of
water and a bit of oil that stays on top so it started to collect oil so
it really collect oil so they started to move actually. It he has collected
oil so this is really from the bits and pieces from the oil on the side so
it started to collect oil but let’s see if I’ve slackened and all these tubes so I just really want to see if how efficient the catch can is. I
mean I don’t really expect it to be 99% efficient but let’s see if really oil
travels up and comes up in the turbo so I’ve really slackened them all so it’s
fairly easy to do so kind of to save time not really film it so first of all there
is not really there is nothing come up coming up here which is quite good I
mean I do not really expect oil to back down the next thing is to really look at it here
where this is the input so if I put my finger well it is quite a bit of oil it
doesn’t really separate everything um so yeah I mean oil travels this is like
that so oil travels and kind of when hits the
border here kind of condenses additionally but the other
thing is if I mean the camera doesn’t really show it but if one really looks
at where the spout comes out there isn’t really much oil accumulated there is a
really a small tiny kind of spot there so I mean the oil goes up there but
what is revealing first pay no attention to the black spots, I’ll
come to that. So and this is like that so the oil that hasn’t been condensed by
the oil catch can will come here so there is a kink so first we’ll hit this bend
so if there’s really a lot of oil it will condense there so if we look just
at the kink or inside there it’s really quite clean not much really coming on
this this bend so it doesn’t really it’s not that much oil just just slightly,
so next about this circular pattern of oil um so you can see it I mean I didn’t
really notice before installing an oil catch can so this is quite oily so what
what happens is really my turbo is 95,000 miles so far
so either the seal doesn’t really seal that well and and let’s a bit of oil
when it spins let’s a bit of oil and it sprays it in that pattern from the from
the turbine or the shaft it’s also slightly worn so it slips a bit of
oil so I mean a way to remedy this is to buy a new cartridge and replace it. I’ll
probably you have to look into that so I mean I’m not removing that hose
because there will be some oil around here and this will probably be full of oil
because it travels from there to the oil catch can and if I
put my finger here there is quite a bit of oil so I mean the oil catch can is not
really 100% removing the oil despite the steel scourers I’m not too sure what
percentage how it what percentages the efficiency of that it’s very difficult
to calculate but what I’m thinking it will be an additional update,
I’ve bought really another oil catch can it’s actually pretty small
oh it’s called kkmon but it’s it’s fairly cheap so inside so it’s an alluminium body insight is yeah fairly small I mean it’s
probably more than the hose of this catch can collect that’s the bottom so at
the top really has a baffle and some sort of a bronze filter here which is
pretty fine so the input comes from here hits this small metal there so it goes
so it goes around and probably goes around coalesces and then this is the
out so the oil vapor comes from this side and goes out, so it’s fairly cheap so I
was thinking fitting basically this oil catch can fit in a
second oil catch can here on that side so the output from this catch can will come
in the input of that one and this will go in the in the intake so kind of a second
just to see if this coalesces a bit more because the gases would have
already cooled down so this might coalesce quite a bit more oil so I just want to
see how much more a second catch can will will help one problem with this is that is that the the spout here is really six
millimeter so it does that’s really nothing so what I have to do is buy some
sort of adapter that will fit in here and it will be whatever 15 or at least
12-13 millimeters so it doesn’t really not to restrict that much the air but that
would be an additional update I’ll probably do it fairly quickly within a week or so
and I’ll put this update and then drive around 500 miles (800kn) just to see if it starts to
collect really quick I’ll do an update quicker so I mean that’s it one really
advice so the bottom hose that collects the oil buy a thicker house or
larger diameter hose than mine because it very quickly collects
within five six seven hundred miles and if the weather is really humid
it collects much quicker so we have to empty it quite quicker and the steel scourers
probably work probably work
I’ll see how well they work I suspect the original one might be
better than this knockoff design but we’ll see with the other oil
catch can so yeah this is this is for now once I’ve installed the second oil catch can
I’ll do another update if there is any change in the collection of oil, thank
you very much for watching if you have any suggestions comments questions let
me know in the comment sections comment section of the video subscribe and thank
you very much indeed for watching

  1. On one of yours previous films you said you have a complete brand new rocker cover. Did you manage to install it or you just replace membrane and the cap?

  2. Am no expert but I don't see any real benefits of a catch can but a few negatives. Why?

    Crankcase pressure is caused by blowby and needs to be to vented. This can be done to atmosphere but is vented much more efficiently under vacuum created via the air intake, plus the environmental positive.

    By adding a catch can you are creating a airflow restriction and thus increasing crankcase pressure above normal, this effectively puts every engine component under additional stress.

    There's little point of catching a teaspoon of oil and some water every 20,000km. Water after all is a product of combustion and in the air you burn. Therefore entering your intake and existing your exhaust constantly regardless. The oil can cause intake fouling but it's minor at best, exhaust gases recirculated by the EGR cause noticeable build up especially if combustion is poor due to wear of other components such as injectors.

    Without a significant cooling system I can't see how any oil vapour at all or water vapour can be condensed other then in the Initial cold start period.

    Anyway that's just my opinion I know the 1.6 hdi has a significant oil in breather pipe problem and you make a commendable effort in attempting to resolve this issue.

    I do enjoy watching your videos, and would really like to see a video in detail changing the coolant on the engine along with the location of the air bleeding screws.

    Keep up the great videos!!
