NO, there is not a pressure relief valve. That is pretty much the function of the overflow bottle.

With a 1.8 you can do the HG's pretty easily with the engine in the car. If you aren't convinced that you have a HG problem, you could check your compression, or maybe a leak down test would be more telling.
