Hi and welcome. Not sure on lagona but follow the top pipe from dip stick should take you to something that looks like a ice hockey puck that's the pcv valve.cheers

 

The cannister where the dipstick goes in , why do you ask ? Have you got a problem ?

 

I have oil weeping out a few of the breather joints so thought it could be the pcv valve, but iv spoke to Renault and on the picture they sent me my engine either has part 9 or part 10 part 10 is the pcv but mine has part 9, so dose that mean my engine dose not have a pcv valve?

 

I ain't got a clue how to attach a picture but the Link below has the diagram half way down the page part 9 is just a straight pipe with no pcv valve but part 10 has the valve and the man at Renault said my engine can either has part 9 or part 10, so mines not got the valve??? Would it make any difference if I brought part 10 with the valve and used it in stead of the straight pipe? I am confused hat the same engine can have either parts, I thought most cars are Ment to have a pcv valve?

Does a Laguna diesel have a PCV valve? I thought they were fitted on petrol engines only (they need manifold vacuum to operate). The diesel engine will have a crankcase ventilation system (CCV) but that could be as simple as a filtered connection. Could be wrong... modern engines still confuse me.

 

I don't know how to attach an image but the link below half way down the page is a diagram Renault sent me, part 9 is what is on my car but part 10 is also apart that can be added apparently, part 10 is the pcv, if it can be added why did they leave it out, any one know a reason for this? He also said I should replace all the breather pipes in the picture as mine are probably blocked and causing oil to weep outta the joints

I have a lag 1.9 and mine doesnt have the pcv , just the pipe from the cannister to the air intake, I suppose it depends on the country and their emissions laws

 

I have a 2l scenic 04 petrol I can find this PCV valve either

 

Hi could somebody please tell me where I can get a new pvc valve for my Clio mk3 1.5dci I can't seem to find any on the internet
