Hello,
I've written that my cylinder head gasket is worn and leaking oil in previous posts. Also, I get a grinding sound when I run the car cold at low rpms. It goes away after the engine is warmed up. Is this the piston rings grinding? I've had worn gaskets before but the only negative impact was the oil would leak and the coolant level would go down too, but no grinding.
What's the grinding?

 

Can you be more specific? Any idea what part of the engine it's coming from? What kind of grinding noise is it?

 

It's pretty hard to tell. I thought it was the power steering pump but from moving my ear around, it seems to be the engine block area. I know, there's a lot of components around the engine block.

The grinding is most prevalent when the car is cold and I'm driving at low rpm's. When driving at higher rpm's, it goes away.
The grinding is not high-pitched. It's low, kind of like rusty brake discs stopping.

 

how long has this grindin sound been going on.

 

Some times when the engine is really cold, the pistons aren't big enough to fill the cylinder, so they bounce around in there. I think its called piston slap. When the piston get hot, they expand and fill the space in the cylinder and the sound goes away. But i don't think the sound would be grinding. The piston thing is normal.

 

The grinding sound has been going on for maybe four months. So, I didn't always have it. I think it may have started when the leak at the head gasket began.
