Whats the easiest way to tell if you have a blown head gasket? It seems I have fumes coming right up in front of me and I here a ticking noise. I though I'd check to see whats going on. Any ideas?
The symptom you're looking for is oil leaking from between the head and the cylinder. This is the line just under where the exhaust pipe leaves the head. If you look at the area right under the exhaust pipe, you can see the edge of the gasket. If it is leaking there, you'll be able to see the oil. In some advanced cases, the oil will be leaking enough for the oil to actually run out across the fins of the cylinder and drip, normally onto the top of the transmission.
The other area you can look at is the base of the cylinder, where it meets the case. You can experience oil seeping out from under the cylinder and down onto the side of the crankcase.
The ticking you hear is either normal valve train noise or it could be the edge of the valve spring retainers hitting the side of the rocker box. This was a common problem with the 07's and some of the 08's.
Good luck,
