on a recent episode of gold rush they had a leak devloped in the radiator of a d-8 cat. with no repair facility close the mechanic put eggs(number?) in the radiator and the leak stopped. this reminded me of a call to the radio show on pbs called car talk. there a caller related being in a rural area when his radiator started leaking and a freind suggested putting eggs in the radiator which he did. the leak stopped was able to drive home and where it did leak again he drove it for a year when he sold it. interesting.
