white sludge in flametrap housing

Ok I know about the PCV system and Jod's excellent right up on the subject of replacing it all which I will be doing in the near future...I do have the typical smoke from the dipstick at idle and had the leaking oil filler cap but I recently cleaned out the flametrap housing to the inlet pipe to throttle body (and cleaned the throttle body whilst I was there and I did a test today and there is white sludge in the pipework/flametrap housing but there is smoke coming out of it at idle (it was removed at the time...) and still the dipstick is smoking when removed a little. So something is getting through the system just not enough.! Questions - is it cleaning itself out after I have cleaned the blocked flametrap housing or is there something a miss? Are these the right parts for mine (97 2.5 10v V70) (however this one does not look like the kit on the car which has two pipes from the flametrap housing back to the oil trap area??) I know I will need a gasket for the inlet manifold and throttle body...are these best purchased from Volvo? Many thanks for your help.

after having spent a lot of money and time getting my 96 850 back on the road i was checking the oil yesterday and there was white sludge also my heart sank however after warming up it went and has not come back i'm thinking the cold weather is causing it so check that first yes get gaskets from volvo

Thank you! I can't seem to find the part on PFV with the two pipes in the one sleeve like this one . They only seem to have them for the turbo models?? :err:

try this link for good info on the 850 N/A pcv parts.... interestingly i was not aware both the 10 and 20v N/A's had the inlet manifold connection too.... The order number is also the volvo part number cheers jod

Volvo main dealer are reasonably priced for the pcv system especialy with your voc discount or try i used these guys for my 850 t5

ha beat me to it jod

I presume that if I go for the 850 10v 97 version it will fit my 97 10v V70?? Is there any difference? I'm guessing no...

Many many thanks...looks like another trip to Tollbar Volvo.
