Im tuning my LEGO LTEC (parody of VTEC) engine to sound like a DOHC 4 cyl engine and I can’t decide which setup I want to use in my video.

Sound 1 has rods that the piston hits to make exhaust popping noise IMO

Sound 2 has the rods removed and it’s the piston sound reverberating inside the cylinder head.

Update: I’m convinced Sound 2 is better.

If I added valves, the engine would rotate too slow and LTEC would not kick in :P My LEGO engines are models powered by a speed controled LEGO motor, not an actual running engine.
