Finally got the time and what a lovely day to do it too. to get to the PCV valves, started with the drivers side as that's where i have the smoke on that bank. managed to get the hose of, and soon as i started moving it, oil started dripping out (PCV valve side) got the pipe off eventually from the rear smaller pipe, and the pipe is actually clogged. there seems to be some kind of hard thing in it, about half way down that seems to be restricting the flow. of what ever it is, to the PCV valve. is this meant to be there, or can i just replace the pipe with a suit able substitute?.

Best off getting a full set from one of the traders. I think mine was about £70

 

The hoses do have stuff in them.

yeah, it has a metal retrisctor a bit thicker than a pound coin, with a hole in the middle, and something that looks like a miniature toilet brush :)

 

I did manage with the correct size pipe to re-use them, but it's a ball ache, suppose you could give it a go, and if it doesn't work for ya then buy the proper ones...

yep got a small metal flow restricter that was jammed full of crap, that needed a very good poke to get the crap out, going to fit a temp pipe for now till i can get a replacement

loo brush thing lol, you lost me there.the pipe only had the metal thing with a hole in it. ive cleaned it up, going to reattach it for now and just replace it as its not that much.

 

Hoping that even with it derestricted slightly that i lose the smoking, ill be a very happy bunny if it does cure it lol

Temporary pipe in place, started the car, gave it a few mins to warm up, and gave it a few revs and no big clouds of smoke. just the normal condensation on the exhaust look.

 

So i have a sneaky suspicion that the PCV valves were the problem all along. but need to get some go go juice to give it a better test. as its running low and i don't want to run it out of fuel.

 

So going to get a 25liter Jerry can and top it up come the weekend and give it a proper test :D fingers crossed, then all it will be a case of doing is replacing them and then MOT time :D

Let us know how you get on with the temporary pipe set up as this maybe my next move. Be good if it doesn't smoke anymore espicially with no metal restrictor!

The restrictor is still in place, i used PTFE tape for now and pushed it into some spare rubber hose i had left over, as its not a permanent fix. i believe the restrictor servers a duel function, 1 to stem the flow of gases, but also as a means to stop oil getting to the valve. unfortunately over time, this gets more clogged until it eventually stops gas getting through completely, and causing the problem.

 

I need to know the route the metal pipe work takes behind the engine, as if you were tracing it back from the plenum, through the valve, past the rubber pipe with the restrictor and then onto a thin metal bit of pipe work that vanishes behind the engine. as this also has a large amount of old engine oil sitting in it forming clogs. last thing i need to do is replace the rubber only for the metal piping to block instead.

 

I left the restrictor in place as its there for a reason. i could try it with out it being there. as the passenger side pipe, doesnt appear to have a restrictor? but i cant be too certain as I'm yet to check properly. only other reason i can see that bit being in the pipe for, is to stop the pipe collapsing on its self at the bend. but its not great enough to cause this.
