Heat riser question
I was under my car yesterday, and noticed that the thermostatic spring is missing from the pass side stock log manifold. My valve is very free to rotate, and just goes to a constant position (engine off) based on "gravity". Anyone know if this "default" position is either open or closed? I had the car out tonight for a few minutes, and just checking exhaust flow "by hand" it seemed like pressure from both exhausts (duals) was about the same. Thx for any feedbck / comments.
