Last night I got to reading about our blow off valves and decided to experiment with an idea to get rid of the goose honk. It worked I think. I drove the car all day and haven't heard a peep out of the goose under my hood. It was simple, I just took the blow off valve off the car and felt inside of the L shaped inlet side of the blow off valve and felt the small hole the factory put right in the middle of the exhaust valve, (I have no clue why), and decided to cover the hole because I read that it was the source of the honk noise. I put silicone on one side of a dime and stuck it over the hole. I let it dry and reinstalled the blow off valve. I,ve been trying to make it honk all day long and it hasn't yet. Theoretically my turbos should spool faster since I plugged this leak but I really can't tell any difference, except in my wallet, because it saved me all that money for a new bov.
