JLT Catch Can results (2021 5.3)

[Stephen Gaze]

Added a JLT Catch Can to my new 2021 LT TB 5.3 at 1400 miles (last Friday). Just out of curiosity, pulled it this afternoon after 150 miles to check. Got some oil already. Just a small amount and only noticeable holding the can at an angle. Looks like the blow-by is about the same as my 496 big block in my old Corvette. Good to see the system is working. I have heard reports of 1/2 a can or 2 to 3 ounces after 4,000 miles. Looks like I will be about the same.

Thanks for sharing, been curious about this myself. I'll be pulling the trigger soon also.

Wise investment for a DI engine.  The amount of oil, oil vapors will definitely cause carbon build up on the back of valves which are dry on DI engines.

I empty mine about every 7500 miles when I do my oil change.  it's always about 1/2 to 3/4 full.
