crankcase ventilation Topic is solved

Is there any maintenance that we have to do with the CV. I have heard
many storries about gasket or oil seal leaking. The car is a v70 t5 2001
Thanks

Rear main seal leaks can be a result of pressure in the crankcase from a clogged PCV system. Regular oil changes will go a long way toward preventing the sludge buildup that can clog it. Synthetic oil is especially good at keeping an engine clean.

thanks dosbricks, and what about the Gunk motor flush? would it be good
for my cars. I have a v70 t5 2001 in great shape and a 850 1993 with
211 000 km with a front crank oil seal leaking???

No way would I put Gunk in the engine; it'll make it leak worse. If you want to use something to clean the engine up, use Auto-RX, but do replace that front crank seal first or you may run in to problems.
