my PCV hoses are blown/cracked and I have waited in the FS section for weeks to no avail. I saw a very nice, still flexible hose (coolant most likely)on an old rusty, Accord engine laying in my yard for months. Its about the same size of the 2 small PCV hoses on top of the valve covers (dont know if original, new oil hoses are hard or flexible but the old ones on my car are rock hard). Question: will this hold up to the PCV job well?
