for all you 250 owners here's what you do to prevent uh carbon just

hey guys welcome back to the channel so you guys follow my project a couple weeks ago i
put in that oil catch can the last couple times i've been driving my car i've been getting a code
for uh too too much oxygen or something like that in the system so i suspect it's got to do with the
pcv valve or something's leaking in it so what i'm going to do today i'm going to test it out
i got to go for a drive right now i'm going to bypass that can again and put back in the
pcv valve the way it's supposed to be and uh i'll see if that engine check engine light comes
on because it usually comes on about after 15 minutes of driving so i'll go ahead and try that
now so i've been getting this p071p072 i think low oxygen in the airstream kind of gives you
the false impression that the maf sensor is bad since both the codes go off if you guys remember
my catch cam video i have a link up here in the top here but i kind of rigged the screen on the
the cap with that thing and it might not be providing a good seal to give a good vacuum
or it could be that the oil water separator that i added that thing might be causing some leaks
where i can't get full vacuum so it looks like that same code p0171 and p0174 i've been getting
so i'm gonna just go ahead and clear that now and put that pcv valve back let's see what it does
this is not good it fell out the backside and i gotta go find the backside hole
oh man that was a [ __ ] to get that thing back there so what happens is the thing is mounted
right up here the tube the other side of the tube is right the back side of the intake manifold
and there's a little guide back there and it goes into the pcv valve right there which
you already know so if that ever pops out you got to have some small hands to get back there
to kind of get that thing back into that slot on the intake manifold
it took me like 15 minutes i didn't record any of it but it was a pain my arm is all scratched up
from trying to squeeze it back there so i'll go ahead and drive it and see what happens
so i've been driving it for about 20 minutes with the engine on i had to stop
get something out of my office and guess what check engine light didn't come on i think my
issue was when i screened thing i did on there it might have left too many gaps on that little
gasket the gasket wasn't really that great to begin with anyways so now what i got to do is just
take the can apart remove that screen that i did tighten it back together make sure everything is
super tight and then i try this again make sure all my connections are good so i might
get rid of that one little filter that i added in line too because i think that filter is causing
this thing to or not pull full vacuum so i'll go ahead and take care of that when i get home for
all you 250 owners here's what you do to prevent carbon just redline a day slow as hell redline
one two three
so looking at this filter that we had to add added in line earlier it actually held and it
collected a little bit of oil on the on the on the return line of that so it was doing its job
i'm wondering if this was causing the leak or was it the can so what i'm going to do actually
if i run after i test this out and see if it works or not i might end up putting this back in
and just to see if it throws a coat or not if it doesn't throw a coat i'm gonna leave it in there
and act as a secondary collection for the oil because obviously i only drove maybe less than
100 miles since i put that can in and look at how much oil already collected here you can kind of
see right there but yeah that's a you know it's a decent amount of oil for less than 100 miles and
you can imagine that going back into your intake and just causing all that carbon buildup on the
head
so i decided to go ahead and put this hose all the way to the back of the intake manifold
so earlier i was saying how it was a pain in the ass to get back there and even a pain it has to
get back there with this hose so what you have to do is to get that hose there's actually a guide
right behind this thing and you just kind of slip it right in and then you get once
you slip it in there you can get it pretty much to line up straight with the the nozzle or the
nipple back there and you just slide it straight in i used that oem clip that it came with that
uh it's back there somewhere but uh yeah it's on the back side right against
the firewall there so basically where your vin number is yeah you just gotta
squeeze your hand back there and hawaiianly kind of push it in and help you get in there
one two one
so i decided to take off that steel braiding that i did last time ended up looking too ricey
for me and the black hoses didn't really look that bad even with the hose clamps
once you put all the panels on you don't really see much of it or notice it so
hopefully now that i've got everything clamped together just the straight hoses that everything's
going to be tight and it's going to get a good vacuum seal i noticed when i was working on this
these little nozzles were kind of loose so i had to retighten those with a 19 millimeter
the one thing i did change up this time was you know earlier when i showed you that i was going
straight into the intake manifold nipple with the hose straight to the can so i did that that way
but then i decided to use the oem angled hose because of the way it comes off the pcv valve
so it comes off at a right angle so it doesn't crimp or crush or do any of that and it lets the
flow go through so i did that and i just turned it this way and then i just connected it right here
with the hose clamps and then the hose connector all the way down to the can so hopefully now
everything's good you saw that i kind of air tested that on a compressor and it held pretty
good air so it was a minor leaking out of it once it goes into vacuum it should be fine it'll
pull the vacuum like it needs to so hopefully that solves that problem that i'm getting with
the leaning out of the whatever sensor picks that up that exhaust gas or that
pcv gas so i'll actually drive around with this for a while and we'll see how it goes hey guys
thanks for watching all the way to the end so i did go road test the car i drove it for about
15 to 20 miles i drove it a straight line and i stopped at some stop lights and drove some back
streets just to make sure that check engine diet didn't come out and it didn't come on so obviously
i fixed the problem i think it was it had to be that rigged screen that i created on the top of
that cap that caused it because i don't suspect that filter being bad because you know if you use
it's the same filter that you use on like your spray gun or on your air tools where so it's
pretty air tight and it lets air flow through it so i don't think that was the real issue it was
probably that rig that did so actually next time i open up the can to check if there's oil build up
or to clean out the can i'm going to actually uh put that filter back on just to see what it does
and if it causes the check engine light again so thanks for watching all the way in again
and don't forget you know the merch i talked about a couple episodes ago it's available on
teespring.com i got a link up here and i'll talk to you guys next time on the next video see ya you
