Don't use cheap turbo gaskets
 

My Evo developed a loud ticking noise. I thought it was my lifters but discovered that it has a blown manifold-turbo gasket.

This was a cheap $15 online gasket (ebay and even Forced Performance sell them). The OEM gasket is $50 retail. My used OEM gasket is still decent. The cheapo gasket looked like an OEM gasket new but after 5k miles, it has totally degraded. I pulled my turbo-O2 gasket as well since it was a $15 non-OEM item as well. It was started to degrade as well. Lesson learned. Buy OEM turbo gaskets!
