2005 Chevrolet Silverado 1500 Question: engine coolant loss
loosing coolant, clicking noise in motor for a few seconds, and now "whitish-blue" smoke coming from exhaust after truck has been sitting for a while in cold weather. Has 115,000 miles on it and noise quites down or doesn't at all in warm temps. or when its still warm. New surge tank cap and water pump installed. compression test done on surge tank and passed. Any ideas? Bad lifters or head gasket? Also, I use synthetic oil and added lucas oil stablizer on last change nothing curing the noise. - dferris48
