Hi guys,
Doing a full boost-circuit check on an RS2 I found that the PCV valve (035103245a) was leaking heavily.
Took it out, cleaned it nicely, and when putting my mityvac directly onto the PCV valve it now leaks out from 2bar to 0 in about 15sec... so a small leak remains.
I said hey, for what it costs I'll order a new one. Got a Febi one and on that it is impossible to build up any pressure... even hand-pumping very quickly can't generate anything about 0.3 bar and bleeds directly to 0.
So the 25 year old PCV valve is better than a brandnew one!
Are these known to remain leaking a small bit (due to the crappy plastic disc design) or should they be completely tight when pressure testing?
Thanks!
