boutle Posted August 21, 2013 Report Share Posted August 21, 2013 Hiya first post! First of all, superb instruction. Now, being a bit tight with the cash at the mo, if I'm extra careful not to break any of the clips, is it possible to just take it all apart and clean out any gunk with a degreaser (method, hot soapy water etc) then stick it all back together, instead of forking out for new parts?

LukeD Posted August 21, 2013 Report Share Posted August 21, 2013 Iv just been reading up about the ccv, to diagnosis a faulty ccv it says start the engine take the oil cap off and put a bag over it and you should feel it sucking in, and another way is to remove dipstick and put a balloon over it and it should inflate, are both these ways correct, one sucking and one blowing? (Don't mean to sound dirty lol) Link to comment Share on other sites More sharing options...
LukeD Posted August 21, 2013 Report Share Posted August 21, 2013 To diagnose will the oil cap and dip stick off would both suck in aswell? Link to comment Share on other sites More sharing options...

I would seriously wait until you've got the cash to buy replacements. The hoses will be very brittle and you're 99% certain to snap something which will leave you with a non runner. You'll also have a real job cleaning everything out, and you pretty much have to snap the valve to get it open to clean the inside of that. For the sake of £90 I'd wait.

(Don't mean to sound dirty lol) I believe that the balloon on the dipstick is the best indicator as it would show what's happening after the seperator valve stage. It should inflate if everything's working properly as the valve diverts the oily breather gases back into the sump via the dipstick.

LukeD Posted August 21, 2013 Report Share Posted August 21, 2013 No sorry I mean if the ballon inflates you need to replace the ccv?? Link to comment Share on other sites More sharing options...

R2D2 Posted August 21, 2013 Author Report Share Posted August 21, 2013 No sorry I mean if the ballon inflates you need to replace the ccv??

Yeah I googled it but it didn't make it that clear, I was getting mixed answers lol, I think I need to replace the ccv on my 325, I took the oil cap off and put a bag over it and it was trying to suck it in, so then I took the dipstick out and done the same with that and the bag was trying to get sucked in aswell, I'm so confused can't work it out Link to comment Share on other sites More sharing options...
R2D2 Posted August 21, 2013 Author Report Share Posted August 21, 2013 Ask it in the technical help section, I'm sure someone will be able to give u a definite answer. I'm sure I saw a thread on it a while ago. Link to comment Share on other sites More sharing options...

RickyZ Posted August 22, 2013 Report Share Posted August 22, 2013 You wont get it out without breaking something trust me I had this done to mine at the weekend, using a mechanic with 35 years experience and some clips were still broken It is an absolute PITA to do, get all spare bits before starting Link to comment Share on other sites More sharing options...
steuk Posted November 10, 2013 Report Share Posted November 10, 2013 Excellent write up. I m going to have a shot at this. Doesn't look easy mind. Link to comment Share on other sites More sharing options...
cash_13 Posted November 11, 2013 Report Share Posted November 11, 2013 Interesting topic I always read that the 3 liter engine drunk a lot of oil and always wondered why well now I know.... Are there any real noticable changes what do I look out for.... my 330 has done 88K and is an 02 plate is this a mileage thing or is it age related too like cambelts etc?

Lee F Out of the two it would be a mileage related weak point because its to do with the amount of oil vapour that the valve has to do with over the years which causes it to clog up. Its not as straight forward as that though because there are loads of other factors that come into how often this will need doing.... how cold the climate is in your part of the world, what oil you use, how you drive, etc etc. Link to comment Share on other sites More sharing options...
cash_13 Posted November 11, 2013 Report Share Posted November 11, 2013 Well its always cold here, but then that could just be my age, how its been driven I don't know for sure but a woman owned it I rest my case!!! Its due an oil service so as soon as its back from the paintshop I will have a close look at the condition of what ever pipes I can get to and investigate it... If I see tell tale signs of any kind of sludging I will order the parts. Thanks for the advice Lee F Link to comment Share on other sites More sharing options...
R2D2 Posted November 11, 2013 Author Report Share Posted November 11, 2013 Another good indication is if you take off your disa valve you'll find oil residue if it needs doing as oil vapour get sucked into the inlet manifold if the separator valve is blocked.

Raj24v Posted January 2, 2014 Report Share Posted January 2, 2014 Are there any visual tell tale signs of my M54 needed this done? Apart from oil consumption? Link to comment Share on other sites More sharing options...
R2D2 Posted January 2, 2014 Author Report Share Posted January 2, 2014 Are there any visual tell tale signs of my M54 needed this done? Apart from oil consumption? As above, your intake manifold will be fairly oily if its gone as oil vapours get sucked into it instead of going down the dipstick and back into the sump.

Raj24v Posted January 2, 2014 Report Share Posted January 2, 2014 Thanks for the reply R2D2, so if I just remove my DISA valve and take a look for any oily residue it should highlight any problems?? Link to comment Share on other sites More sharing options...
R2D2 Posted January 2, 2014 Author Report Share Posted January 2, 2014 Yes,just take the disa valve out and any oil residue will be fairly obvious. It's normally a hint that things aren't right if it's too bad, bearing in mind that older engines will have a slight build up in the intake anyway, but too much is usually down to a goosed separator valve.
