[QUOTE="Rod Helstad, post: 768273, member: 53749"] Whenever I start my 08 v8 when it is cold, there is a very annoying whistle coming from the engine compartment. The only day that it did not do this was when I dropped it off at the dealership the night before to have it checked (murphys law). It sounds more like a vacuum leak to me. I have turned off the heat/ac to try to figure out if it was tha ac compressor, but it still happens. It only will do this for about the first 5 minutes, then quits when the engine is warm. I even put the original air filter back in thinking it was the additional air flow through the K&N, but it is still the same. I have another appt. for Thursday AM and will leave it outside at the shop so it is cold. Any suggestions????? Rod [/QUOTE]
