For the serious engine builder, or the novice tinkerer, a cam plate pressure relief test tool from Feuling allows you to correctly check the pressure relief valve on your twin cam engine's cam plate BEFORE it’s installed.

You’ll be able to know the exact pressure at which the relief valve opens thereby allowing you to precisely set spring tension at the desired level. Additionally, any leakage will be noticeable so you can rest assured your next build is going to be oiled properly.
