Hey Guys,

Got a strange one. I have an '02 GT. L36.With about 67,000 miles. When I first start the car, it has a strange knocking sound.Then after a cpl of minutes,the knock goes away. The car seems to run fine. No oil burning. It does seem to be losing coolant,however.And I can't seem to find the source of that leak. any ideas?

Thanks for any help!
