Hi everyone. So I was on my way to work this morning when the engine suddenly died and wouldn't start. I was able to coast into the Sunnybank Plaza carpark (for those of you who know where that is). I'm pretty sure the head gasket is gone because the oil definitely seems watery on the dipstick and under the fill cap. A couple questions:

What is a reasonable price to fix the head gasket and change the timing belt (it's due for it)?

Is there anything else that should be done at the same time? Maybe the water pump?

I'll probably be getting the work done at the Kmart auto place. Definitely not my first choice, but it's either that or pay for it to be towed somewhere else.

Any suggestions or expertise would be very appreciated!

Mark
