I replaced mine in about 20 min, you just have to unbolt the hard pipe to the pcv valve on the block which connects to the intake and remove some hose clamps. If you have an 02 you might be eligible for a recall on that part. Apparrantly they did the recall based on vin numbers, and even though mine visibly ripped in multiple spots they still made me pay for it. Typical stealership bullshit.

BTW I'm talking about the crankcase breather hose which is attached to the block or intake mani (can't remember which) but it's at the back of the engine and is a T-shaped hose. Hope that helped
