First try bending the tabs on the cap a bit to tighten it up. Also check to see that the clamp in the hose coming from the radiator neck is holding tight. It is common for that clamp to leak. Replace it with a good stainless worm screw type.

I read somewhere to pinch the tabs on cap to hold tighter, I just backed off half turn on pressure cap.

Bend them in. If that doesnt work, just get a new one. It shouldnt be to much just remember not to get the spring type.

This is highly typical of our OEM Radiators. The system seems to not be able to flow enough at high engine speed, so pressure builds up and leaks at the hose or usually the Cap. Our overflow bottle is part of the pressurized system, and you need free flow between the neck of the Radiator and the Overflow Bottle. That is why you must use an OEM Style (Non Spring) Radiator Cap.
