+robster+ 39 Posted March 6, 2013 Share Posted March 6, 2013 positive crank case ventilation.for emmisions on turbo cars it lets the vacum from inlet suck the blow by from the crank case into the inlet to be reburntwhen hitting boost the manifold pressure blows the valve in the other direction to block it so your turbo pressure get lost and even blow the dipstick outon my subaru it was just a shuttle valvea ball bearing in a journal ( inside a hose fitting from the crank case vent) that moved with vacum or pressure to block one direction or the othera clean with brake cleaner was all that was reqd if it gummed up with the Oil vapour from engine breathing.the fault was a loss of turbo pressure.it was very simple mechanicallyon my scoob i vented to Oil catch can then atmosphere and blanked off the hose to inlet returnhow does yours operate?

+robster+ 39 Posted March 10, 2013 Share Posted March 10, 2013 why do you need onewhat are the symptoms on a non turbo car ? blocking of engine breather causing Oil leaks/ flat spots/excess pressure in crankcase??for the price of a pizza order id get one or do the vta or Oil catch can mod if you have someone that knows a bit about engines and can help.at this price id say its a mechanical device and should be able to be cleaned via some brake cleaner or removing it and leaving it in a aerosol cap full of petrol or diesel to clean it out?can it be removed as a servicable item?is it a more complex part than im thinking of?hopefully tspiritpete will have an extract of a parts or service manual to see what this is all about as he seems to have nice wee nuggets of info for things like this Quote Link to post Share on other sites
