Hey guys,

I've been having an issue with my 99' Impreza GF. Started to develop a slight tapping noise last week from the engine after a medium pull to 5K.

The tapping is most noticeable under load around 1500 - 2500 rpm, and heaps louder when the engine is cold. The tapping is related to rpm. It's more of a high pitched tap.

Went through all the basics, and have determined it's coming from around cylinders 2 & 4 by using a stethoscope. I had to give it a solid rev to hear the noise while stationary. The noise is most apparent a bit behind the valve cover gasket on the top of the engine.

My guess is valves need adjusting, but really, take that with a grain of salt. I haven't been working on cars for very long.

Any opinions?

Cheers
