Head gasket seal? I didnt know that thing problem can cause overheat.

guys...really need your help here.

my persona elegance...today morning wanted to drive to work...when open door find some strong smell inside car.

then found out got water leaking/ stagnant at the carpet.

took out the rubber mat...oh boy the mat was pretty wet with water dripping.

the worst is the driver side and the back of driver side.
the carpet floor for both driver and rear driver is really wet.

the passenger and rear passenger side  carpet floor is also wet but not as bad as the driver's side.
anyone here got any idea what is the cause?

is it the door rubber sealant or the plastic water shield behind the door panel?

or is it the undercarriage?

anyone can help me out here?

if one place wet i'm ok...but to have all 4 carpet wet at the same time...i'm really confused right now?

Can telco equipment block car key signal?i cant lock my car when near  this shop that have install telco equipment on top of their roof.if move other location no problem..this shop only 2 floor maybe too near?

Sorry my fault. Both owners manual and service booklet did not mention timing belt change mileage or time.
