Oil Cooler: Does yours cause a whine? I have a fix!

So I noticed a few other people here talk about a whine that started after installing an oil cooler. I talked to Dustin@Z1 about it, and he said that they have seen this occasionally and thought it was a resonance from the oil flowing through the line and that line touching the frame of the car. This noise was really bugging me, since it was pretty loud and I could reproduce it all the time, usually any time above 3500 RPM's.

So I went to my local hardware store, and bought some thick rubber hosing, I think it was the kind you would use for a water heater. I took off my bumper and the various pieces where the lines are being run, and I had 3 spots where the lines were against the frame. It took a bit of time to wrap the line with the hosing, since it was so thick and the spots are tight, but I managed to get them all.

After some extensive driving and hitting various speeds, rpm's, and gears, I can say it is about 90% gone. Only time I can still hear it a little is in a very specific RPM range in a specific gear (I think it is 2nd @ 4500 or so). Other than that the sound is completely gone.

Not a bad fix for about $8 worth of hosing. Just thought I'd pass this along in case it was bugging anyone else as much as it was bothering me.
