Hello all,
I have a '98 GT w/ 47,000 Miles on it. I noticed over the past few winters that when the engine is cold and I start the car I get a clanking sound coming from the engine for no longer than 2 seconds. It almost sounds like a bunch of marbles bouncing around in the engine. The only time I hear the noise is on start up. The engine sounds and runs fine after I hear the noise. It only seems to do it in the winter....it doesn't do it in the summer. I am using 5w-30 Valvaline Durablend and a Motorcraft filter. Any Idea's on what this noise is and how to get rid of it? Any input would be much appreciated.
Thanks

This sounds normal to me. When it is cold outside, engine oil is very thick and reaches the moving parts of your engine at a slower speed than during warm weather. So for 2 seconds, you have no oil in your valvetrain and it makes some noise becuase of this. I wouldn't worry about it too much.

Also, might want to go back to 5W-20. The 20 is the weight that the oil acts like when it is cold wich is a little thinner that the 30. The engine might have a little problem getting the 30 weight to flow into the bearings.
