Review on 🔥 JLT 3.0 Oil Separator 3086D-B: Enhance Performance of 2019 Silverado 1500 Sierra 1500 5.3L - Black Anodized by Jonathan Wilson

I have 3 GDI cars (Gasoline Direct Injection). I just bought this JLT unit for my 2019 Silverado Black Widow to prevent EGR gases and oil from going back through the throttle body and they weren't holding together. valves up. These JLT blocks pull the EGR gasses out of your PCV and direct all of the oily water into the trap instead of the throttle body and valves. This reduces the possibility of excessive deposits and damage to the valves. This is especially important for GDI engines as the fuel mixture is no longer dumped out of the valves where they are used to keep the valves clean. In GDI engines, the fuel is fed directly into the cylinder. However, these JLT blocks are indeed a good preventative measure to keep your throttle body and valves clean and healthy.
