MOT fail need help with emisions…

@cea85142f6=jamesmx3:
no, is that the little 90deg bend tube that comes from the valve cover?
its the pipe rom the camcover to the induction pipe please correct me i wrong but pritty sure
-
thats the crank breather, the pcv is the bit on the front valve cover that is 90deg, im struggling to tell the difference tbh, from what I can piece together the crank breather sucks in filtered air through the intake tube abd the PCV then allows it back into the intake manifold plenum, took my pcv off tonight cos i wondered which way it flowed (since im not really sure on the system myself) and its flows away from the engine, ie, i could blow into it, but i couldnt suck through it.
Which is what leads me to believe that the air is drawn through the crank breather, through the engine and then out through the PCV back directly into the intake manifold plenum. Someone correct me if Im wrong as I dont want to give bad info.
-
my mistake thanks
:oops: :oops:
-
thought to ease any confusion i should just say that i was blowing into the pcv unit through the bottom of it, ie the part of it that sits inside the engine not the other end of it that has the hose running to the manifold
-
took the car in for a test again after changing plugs,exhaust sensor, RC gasket.
result…..
Failed on emmisions, but only on CO this time, not Lambda(sp?) and head light aim and a OSR caliper not up to standard?
So new cat on its way, and im a little confused on how the headlight aim changed from the last MOT, and how the brakes have managed to deteriorate in the 6weeks its been sat still?
Ive had the Hbrake off and it left in gear. Grr!
Was seriosly considering buying a new car, but then I thought if I can spend maybe £200 a year to get this through the MOT, then its not worth it! Considering Ive only driven 5k miles since last MOT.
-
In u.s they swear by product called seafoam. I'd be tempted to try that.
-
Dont think seafoam is available over here, never seen it anyway, probestore sells cataclean, seen that in both the local motor factors, £15, surely worth a try, many say its good.
-
be handy if you knew someone with a emmisions tester to check before and after results before paying for mot re-test ( unless you dont have to of course. )
Ive got to get my emmisions lower this year. Dont think they will use another car for emmisions for the 3rd year running!
-
I used a bottle of cataclean, got another one too!
cat should be here tomorrow, and need to fix the calper and light, then try it next week!
yeh wish there was a way i could test it before the MOT, problem is now its run out, I cant drive anywhere but to an MOT test!

youll be able to check it against the failed mot emissions values if you got a print out?
