So I got the po171 and PO174 codes, looked for the leak, and found the pcv hose to be cracked where it meets the front of the engine, pass side. I glued it for now, but was wondering if it is normal for that elbow to be crushed while the engine is running. I assume it's got a good vacuum, hence the crushing, but is that normal?
If that's the case, then a pice of hose should work fine, right? I used 5/8" ID tube for it, and it also crushed while running. Just wondering if that 90 degree bend should hold up to the vacuum or not.
There's a pic of the bend I'm talking about on this post....
