Have a 1998 V70 GLT which apears to leak oil out of the top of the dipstick tube. Any ideas? Bad PCV valve? Please advise. Thanks!

Your car should be non turbo check the PCV system it is probably clogged somewhere.Building enough pressure to make it come out the dipstick tube there is a clog somewhere.You should try to figure it out soon before it starts blowing the seals out.
