Recently bought a v70 2001 2.4 non turbo got her home noticed oil pressure warning looked underneath and found all the engine oil leaking out. Did a bit of investigation found Pcv completely clogged removed and replaced removed sump and cleaned channel that connects to PVC changed oil filter and dip stick gasket run her up today and started to drip oil again not too much just one or two drops. Could I have blown the crank seal due to Pcv failure ? The oil seems to be coming from around the bottom of the timing belt
