I've been wrenching on LS engines for years, from street trucks to track beasts, and one nagging issue always pops up: oil vapors sneaking past the stock PCV setup into the intake manifold. That oily mess coats valves, fouls spark plugs, and robs power while smelling like burnt french fries under the hood. Enter this aluminum LS oil diverter barbell—a no-fuss upgrade that routes those vapors away before they cause trouble.
The factory barbell on GM Gen III and IV LS engines (think LS1, LS2, LS3, LQ4, L92, and all those 4.8L to 6.2L mills) is cheap plastic. It works fine at stock power levels but cracks under sustained heat, boost, or nitrous. This one's CNC-machined from billet aluminum, so it laughs off 500+ degrees and stays sealed tight. No more leaks, no more vacuum issues—just solid performance.
Slap it on your Silverado daily driver, Camaro weekend warrior, or full-race Pro Mod. I put one on my '05 GTO with an LS2 and immediately noticed crisper throttle response and no more blue smoke on decel. It's especially clutch for cammed setups or supercharged builds where crankcase pressure spikes. Pair it with a catch can for ultimate oil control, and your engine stays happy longer.
Installation? Drain the oil, pop off the valley cover, swap the barbell, torque to spec, and refill. 30 minutes tops, even solo. No special tools, no drama. If you're chasing reliability in your GM LS swap or hot rod, this diverter barbell is the quiet hero your build deserves. Grab it and forget about oil worries—focus on the drive instead.
