How to replace a PCV valve on 1.6HDi/TDCi engines (Peugeot/Citroen/Ford/Volvo), the correct way!

Rocker Cover part number: 0248L1 (amazon UK): amzn.to/3D7hWSG or ebay: ebay.us/tnK1bx
Sometimes this part number refers to the whole rocker cover including the PCV valve cap with membrane and the oil filler cap.
The PCV (positive crankcase valve) of the 1.6HDi/TDCi engines is integral to the rocker cover. This is how to replace the diaphragm, as part of the PCV. I made a previous video and made a complete mess and broke all the plastic pins of the PCV valve cover. The video is here: • How to (or maybe not t...
Sometimes you may get a bit of smoke constantly from the exhaust and the PCV membrane might be broken, this was not the case in my engine, but worth a check.
The car is Peugeot Partner (2007, 90bhp, no DPF, M59, 1.6HDi, ~106k miles).

I only had that thin zip tie, but a slightly thicker zip tie will work better and you can simply push every tab, with one filed edge of course to go underneath the plastic tabs. I learned my lesson and I am not a "cowboy" anymore ;-)

Personally I have not heard of the P2002, but it seem that it is related to low DPF pressure. It seems that the DPF hoses perish and one needs to replace them. I cannot advise on how it can be done, but quite a few forum pictures around the web, seems fairly easy to do. Good luck. My car does not have a DPF, so difficult to tell how to do it.

Thank you. Is there any way to test if the PCV valve is working correctly before you open it, as shown or can you test it after you have opened it. Do owners normally order the full plastic housing unit, including the Oil filler cap and PCV valve as a full replacement?
@moremolecules
@moremolecules Жыл бұрын
The way it is designed there is no way to test it before opening unfortunately. I normally order the cap + the membrane and spring (links in the description of video). It is just safer in case you break some of the plastic pins. Previously I bought the whole thing, but recently there have been ebay sellers that sell just the cap and membrane. It is cheaper and less hassle than replacing and sealing the whole crankcase cover.

hi! ı just wonder why you removed oil catch can in your car. I have followed you about 1 year and whole videos are very useful , thanks a lot .I decided to add oil catch can my car .(which peugeot 307 1.6hdi) but when ı saw your new video with no oil cacht can, a little bit confused about catch can installation, am ı on correct path or not about setup catchcan :)
@moremolecules

Very simple reason. Every year I have to do an annual inspection for roadworthiness of my car and they do not like any modification of the car. In addition, this is a modification to the emissions and they will fail my car. So every year I remove it, fit the standard stuff so to pass and then it takes some time to put it on. I do film a few videos in between, hence I do not have the oil catch can. Sometimes, I remove it in order to film a particular video where it is important to show the original setup.

I cannot say for certain, but it could be. Mine does the same and I have not yet found the reason. I will try some other things in the next month or so and will post the results. It is to do with the cold startup smoke. Depends on what the smoke is of course and the temperature of the weather.

I just got a plastic milk carton and cut some thin strips. I then pulled back the bottom part of the clip slightly and pushed the plastic strip down from the top on each tab - came off easily. I am still wanting to do the timing belt on my 2012 Citroen C3 Picasso 1.6HDi so an 11 year old timing belt with 70,000 miles. It just scares me a little bit and only having the one car if I get half way through and then find I need a part/tool I don't have then I am stuck with no car to go and buy it. I have to do it this summer though.

Yeah, first time I tried with screwdrivers and ended up breaking all of them. With the zip tie it seemed to work without a problem, but I suspect they can still be broken. I think the trick is to have the engine really hot and do it straight away, plastic is more pliable and less prone to breakage.

Good evening. Instead of just changing the valve, I replaced the entire valved top. With the new part, the car smokes excessively. A lot of pressure builds up inside the engine and as soon as I open the oil cap, it expands. I put the old part back in and after a while it stopped. With the new part, it is difficult to suck in the air, with the old one, there is no resistance. (Where the part is connected to the turbo intake pipe) what is normal??? To have suction resistance or not??? As far as I know it should be open at idle and close when the engine revs up. Do I know something wrong??
@moremolecules
@moremolecules 10 ай бұрын
If it is smoking with the new valve top, then something with the spring/rubber membrane that is integral to the valve cover is not right. Probably too tight, you may want to extend the spring a little bit. Difficult to say how little. Say 1-2mm and see if that helps. There is simply excessive crankcase pressure and nowhere to go.

@@moremolecules Good morning, thanks for the reply. That's what I thought too. The company I bought it from will send me a new one. I'll put the new one in and see. Is there a surefire way to test it before I put it up?? How exactly does the valve work?? As far as I know at idle it is almost open and as soon as it starts revving the engine closes a bit so that the turbo does not suck from the engine. Do I know something wrong??

@moremolecules 10 ай бұрын
@@EfthimiouTheodoro I do not think there is a way to test the new membrane/spring combination. Only thing you can probably do is compare the strength and size of the two springs. You are correct that it keeps it open and when the turbo starts sucking air it closes slightly and on full blast it completely closes, although there is still a bit of opening otherwise you would get a lot of pressure in the engine.

pass string through a piece of plastic tube with length equal to the width of a clip. Then pass ends of the string behind each corresponding sides of a clip, exiting outwards at center, accordigly. Pulling equally on both ends will pull tube upwards under the clip,, forcing it to open without damage. Then tying a knot/bow on the string, will keep the tube in place. Repeat on all remaining clips. I have not performed this method. But however, as i am a genius, i know it will work perfectly. trust ?
