In the process of doing the usual bits on my 55 GTI (just done DV and amazed at the difference it made) but bit confused about the PCV. I know there are different revisions for early cars and later cars with and without a check valve.
Searched through threads but can't seem to find an answer for this. Mine is a 55 so does it need the latest revision that comes without a check valve pipe or do I need the latest revision and also to buy the check valve pipe to replace the pipe I have already? If I just need the PCV without check valve pipe, do I also have to replace the surrounding pipes (I know the rubber seal has to be replaced) or is there no need to replace it as the pipe doesn't have a check valve and therefore would not need replacing as nothing could be broken with it?
Sorry I know the whole PCV thing has been covered loads but it is hard to find definitive answer on the whole check valve pipe situation as it seems from threads I have read a lot of people have mistakenly bought the check valve pipe for their car when it didn't need it and ended up with the engine running funny.
Thanks!
