am i under the inprestion at you can remove the pcv and if thats the case what dose it do and what would be the concerns if any if removed

Hope this helps. http://www.z32photoguide.com/emissions.html#pcv. http://www.z32photoguide.com/emissions.html#pcvloc

 

If you remove them you have to make a catch tank arrangment, which is not as simple as it seems, best stick to the pcv's.

I'm sure i read somewhere that to remove the PCV valves you need to hook up a pump or something to create a continual vacume? It was pretty recent i think to :confused:

It helps vent the oil vapor from the engine crankcase. If you take them out without plugging the hole you will have oil coming from them and if you block them you will have pressure in the crankcase which will force oil out the dipstick.

What are you reasons for wanting to remove them ?

because im at the understanding that the pcvs can cause smoke from oil build up in them causing smoke from exhaust. why can i not ventilate some how from each cyinder head, and put a breather in or, is this not poss because of pressure issues?

Yes they can cause smoke, but that's because they're blocked. Would think it's much easier and cheaper to just replace them.

They cost about 10 pound to replace, they only cause smoke if they are blocked/seized, and need replacing.

engine out just thought do i replace or get rid

You can chage them in situ :)

Is it only the valves that get blocked? Can the rubber pipes or the metal pipe that wraps around the back of the engine get blocked also? Is it worth blowing an ir line through them ??

I blasted all mine out with carb cleaner so they are all nice and clean. You can buy new pipes from mike (trader) as the old pipes may be brittle

Yes the pipes have restrictors in them that can potentially get crudded up.

can i buy a knew pcv kit with all new pipes

Yep! usually a stock item with mike feeney at MJP in the traders section

can i buy a knew pcv kit with all new pipes

 

Yes, DTA, MJP Zcentre all do kits.

Only £4.50 at MJP currently... (Or at least they were)! Ooops

Have these items suddenly got cheap......or am I missing something here. The last kit I bought which was the 2 valves and new pipes which as stated have springloaded valves in them, cost me £70. :mad:

Not the kit - just the valves - soz.

so the valves cost me.4.50 each and i buy a reel of silicon hose.in blue

Hi,

 

I know we only just talked on the phone about this but in the interest of keeping information in this thread factual allow me to say the following.

 

There are two different types of silicone hoses: (1) Vacuum tubing, which is often sold in meters or on a reel, and (2) silicone tubing, which is often sold per meter length.

 

Vacuum tubing, although made from silicone, is prepared via an entirely different method than pure silicone tubing. As such, vacuum tubing is ONLY suitable for clean AIR applications. The PCV system carries quite a bit of oil vapours which will eventually corrode the vacuum tubing. So, for a PCV application you require SILICONE tubing. Next thing to realise is that you can only bend silicone tubing to a certain extend without loosing structural integrity or causing it to collapse in on itself. As there are a couple of PCV hoses with near 90-degree bends in them you will need to buy pre-formed silicone tubing to replace the OEM hoses.

 

Now for a shameless plug, as luck would have it I can supply all sorts of silicone and vacuum tubing. I've also got access to silicone PCV hoses. For more information/prices please contact me on 0845 4744382.

 

Hope the above (technical) info has been useful.

 

Regards,

The hoses that attach to the actual valves have little brushes in them to stop hard debris clogging the valve right?

 

But they are only little brushes right - nothing special?

Question for you really Dan ;-)

When I did the PCV re-route - I used 2 x new passenger side hoses (11823-P01) and then a 10mm barbed hose joiner to attache the braided to the new connections - I assume I could have just as easily connected directly to the PCV valve with any reducer right? And or just spent 50p on two pipe cleaner/brushers to place in the pipe or maybe just a wire filter for free? Hmmmmm!
