I was wondering, if you had a blown head gasket, you would lose oil pressure right and the oil light would come on constantly? and also a drop in compression too??? I was just wondering cause my engine (b16A2 2000 Civic si) loses about a half quart of oil a week about. I rarely hit VTEC but someoe told me its normal for VTEC engines to lose a little oil once in a while. I have good compression definately(200,200,195,190 in psi). Anyone help, thanks!
