One of the most common questions I get from diesel owners is: Will the Sentinel exhaust brake cause my valves to float? Let me set the record straight — the answer is NO, and here’s why! 🙅♂️The Sentinel exhaust brake system is orifice-controlled, meaning it only allows 70-75 PSI of back pressure to build in your engine. This is far below the threshold where valve float becomes a concern. To give you a bit of perspective: on a stock 59 with 60lb valve springs, you need about 92lbs of pressure for the valve to start opening. The Sentinel system stays well under this level, ensuring your engine stays safe and runs smoothly.Whether you’re working with a stock 59 or a 12-valve, the Sentinel exhaust brake won’t interfere with valve function or performance. It’s designed to work harmoniously with your engine, providing optimal back pressure without causing any issues.So, if you’re worried about your exhaust valves floating, don’t stress — the Sentinel exhaust brake system has got you covered!
