Had a variation in my idle so my mechanic said to change my pcv valve. Did so and now it smokes n stinks terribly. Bought china pcv. Bought a second one and problem persists. Definatly pulling oil from crank case. I have ordered a new pcv from land rover and am waiting on part. Is there something i am overlooking or am doing wrong. Please help me. I am disabled and only get one check a month and cannot throw money at a hole in the floor... Thank you...
