车库里的废气可不能跑到屋里去。汽油味还好，汽车尾气可是有毒的。

自己可以查一下房子和车库间的门，密封条有没有破损或是老化？另外，你的房子过去做过builder的sales office吗？要是这样，查一下是否有通到车库的暖气管没堵好？要是车库的顶棚上面有通往attic的洞，看看盖子是否关严了？要是这些都没问题，就得请人看看了。

You also should check where the gas smells from is. Is it a leak in your car, lawn mower...? They are also dangerous. And you should not run your car in garage without the garage door open.

I think it maybe from the air vent in the loft, but the ceiling and one wall in the garage was insulated and with drywall on it because these two parts are part of the house( the builder is bad,they don't finish the other two walls because they are not connected with the house). Is there any tools/instrument/meter I can use to check the waste gas rate? I didn't park my car in the garage, the smell is come from the law mower.
I complained this with builder,but I don't have evidence for the smell, the person who come to check said he didn't smell anything.The garage door seems good, from inside I cann't see any light in the garage.
Any comments?
I found out typing english is more faster than chinese, although it is more harder to read. Sorry about that.

Thanks for everybody who replied me.

Are there any chance the air vent tube go through that wall or ceiling in garage? And are the drywall be painted or just bare?

I think the air vent go through that wall and ceiling,and the drywall are not painted.

I think you can try some "smoke" producing devices, you may able to rent one in HD(I don't know. you can ask the people there). Put you air condition on to see if any smoke in the garage will go to the living room. There is a chance the leak is along the air tub. Because there usually a gap between the tub and insulation. The wall in the garage may not have a vinyl film under it.So it is not air tight. They did not paint it.so the gap between drywall was not filled. The smell may leak to the wall then follow the gap around air tube to the living room.

You mean vent dust go throught the garage ceiling?

Dust要是贯穿车库的隔墙和顶棚，难看不说，还得密封和保温。费力不讨好，builder该不会这么做。它要经过车库，多半是从ceiling上面走，并有保温棉护着。

一种该注意的例外，要是这房子过去做过sales office，车库可能被用作show room。这时候builder会用个临时的管子把热风接到车库里，待房子卖掉时再把它拆了或堵上。要是车库里真的有这么个风口，得好好看看它是不是已经堵好了。

你的房子不像是这种，因为车库里的drywall没有油漆。我出个主意，花不了几个钱，但有些费事，也不知能否找到毛病，仅供参考吧：

先试着把屋里的门窗全关好，出风口关上，要是有回风口，也用东西把它罩起来。然后把车库门关紧，在车库里点上几柱味道重些的熏香什么的－－千万注意防火。

待香燃尽，看看屋里有什么味道。然后打开回风口试试，最后再试试打开出风口。

要是熏香的味道真能跑到屋里，就真得找人看看啦，garage往屋里漏气不是小事。

嘿，我也出了个差不多的主意。什么“所见略同”来着？要不，咱俩就都当回英雄？

按建筑规范，garage和living area之间必须是air tight，而且隔墙还有防火要求。只要能证明是漏气，就肯定是哪儿做错了，叫builder派人来修吧。

Yes, it is as you said.

在墙的上面那个口是return air。

熏香可以在１６８或其他中国店里面买到。另外，Canadian Tire该有Timothy说的那种供紧急停车用的发烟的东西卖－－我没专门去找过，可我买的一个emergency kit里面有两块这种东西，点着了以后冒很浓的烟。

Did you put your central Vac unit in the garage? I heard that the Central Vac unit can leak exhaust (or other smell) into the house and that is why the builder never install central vac in the garage for you.

找出毛病了吗？

刚才见到这么个网页，忽然觉得也许对你的case有用。Link:

若自己找不出漏气的地方，可以找人做个pressure test。据称价钱在两百以下。祝你好运。
