This morning I started the car. (It was only 5 degress (F)) and it turned
over slow as usual in cold weather but started. After it ran for 20
seconds, it began making this slapping, clattering, chattering, knocking
noise. It sounded almost like hitting a marble with another marble over and
over at a very fast rate. The noise was going at the same speed as my
engine. The noise was almost as loud as the engine itself. The noise went
away after a minute. I've never noticed this noise before even on days when
I have managed to get the car to start on days where the temperature is -3
F. (Although that's only a few days out of a year.) The only difference
between then and now is I'm using thinner oil. I'm assuming it was just
because of the cold but it might be signs of something happening. I know
it's harder to tell what it is without listening to it, but do you have any
ideas of what this marble hitting a marble noise is? Thanks.

From what I've heard, it might be the rockers.

you didnt say what weight your using but sounds like a lifter not
pumping up like it should causin the rocker arm to tap the valve.

I'm using 5W30 oil, and I just changed my oil last week. I was previously
using 10W40.

Secondly, is this something to worry about or not? It only did it that day
it was very cold.

i dont think it will hurt anything unless it does it all the time.

the grankcase. Drive reasonably for about 50 miles or so with the MMO,
then have oil drained and change filter. Put Bardahl 2 or Lucas oil
stabilizer (I'm partial to the Lucas) in the new oil. If it's a sticky
lifter, this will USUALLY fix it. It helps sticky valves too - and a
bit of MMO in the fuel can help there too.

That's what I thought, but I was just making sure. Thanks.

If the problem comes back or starts doing it more, I will do this.
Presently though, it only did this on the coldest day of the year.
