I've heard of having the same problems even using the regular intake. When you take it apart is it blowing in the same general spot? It may be time to take it to a machinist.
The first time it went out, both the front and rear rails were leaking. This last time it looked like it was just the front, and a much smaller leak. I put it back together and so far so good. If it goes again I'll have it checked out.
