Q: Need estimate to replace the crankcase breather? Loud whistling noise f-engine on 2002 Volvo S80

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
Loud whistling noise from engine after about 4 miles (very hot TEXAS weather). One mechanic thinks it might be the manifold. A Volvo forum suggests crankcase breather (or Vent Box).
This 2002 Volvo S80 is NOT a turbo.

Check the crankcase breather hose under the manifold, near the power steering pump area. This is a common problem where the hose splits and makes a whistling noise. You may need a flashlight and a mirror to see it.
I had same problem. You have to replace the crankcase breather also called... breather box, flame trap, oil trap. 2 different Volvo dealers quoted me $800 and the other $1350. Go to a independent Volvo mechanic. I got mine for $450 installed. The part in not expensive, but the labor is around 4 hrs. They have to take apart a lot of the engine to get to it. If you don't have it fixed, it can cause your seals to leak.
