I want to install a extra heater to my car and i have question about grounding.

I have AC 220V 400 heater that i want to power from the walloutlet. Can i connect the mains-ground to the car chassis or will i have problems?

The negative terminal of cars battery is connected to the chassis of the car.

Do you have any idea what the fuck you're doing?
Your car is 12VDC. The heater is 220VAC. What you want to do will do NOTHING.

Get the heater in your car fixed if it doesn't work right, or dress in more layers if you're cold.

you need to read the OP post once more. I am powering the heater from the 220 AC mains.

It won't cause any problems for the car battery, but I don't understand why you want to connect the mains ground to your chassis in the first place.

Incase my diy heater breaks and the chassis gets the full 220VAC. I want the mains fuse to blow.

Just another path to ground. Don't wire it up to a GFCI breaker, though.

Is this a block heater? The kind where you just punch out a frost plug and install it without any complaints? I'm a little confused, I've installed a few block heaters into cars here in the great white north and had no issues so I'm wondering what type of heater you are referring to and why you would want another one?

Yes, you can. It will probably not be of any use though, if the heater itself is already grounded.
