Piston Slap: The Last Frontier, The Dreaded H*** G****t?

Sajeev,

I am a newbie here so I am not sure that I am posing the question in the correct cyber-manner but here goes: I purchased a 2000 Nissan Frontier 4-door truck new in August of 1999. It has 112K miles and I have just replaced the clutch: it was the training vehicle for my teenage daughter. I have a son who is 13 who will also learn to drive on this vehicle, then it will be put to pasture.

When I took the truck to my mechanic to get the new clutch I told him that I smelled burning coolant when I got out of the truck. He did a pressure test and said it came from the radiator, which he replaced.

I still smell it however and I need help. There is no puddle of coolant under the truck after it has been parked. I replace about 1 quart of coolant about every two months or so but it is not disappearing rapidly. I have been resisting using the words h*** g****t for fear that he will recommend replacing them to the tune of big $$$. The smell is strongest under the hood. I don’t smell it near the tail pipe.

Please help. We cannot live without a truck in the family.

Three minutes later, the Dali collided with the bridge. Nothing suspicious at all. Let's go get some booster shots!
