My name is Rob and I have a 1998 GMC Sierra 1500 4WD, 5.7L Vortec, Z-71 with 80K miles. Last Sat I started it up and white smoke bellowed out the left tailpipe. I suspected a blown head gasket. Took it to the garage and they confirmed. Repair claim consisted of gasket replacement, turned both heads, new bolts, plugs, oil, coolant. I picked up the truck on Thur, drove less than 2 miles and with no warning a loud knocking sound came from under the hood. I immediately pulled over and inspected to find a puddle of oil under the ingine and a rod protruding from the oil pan. I am almost certain that this problem is a result from something that wasn't repaired correctly when the head gasket was replaced. Can you please provide insight as to why a rod was thrown after only driving less than 2-miles at low speed. Your promt reply would be greatly appreciated. Thank you much!
