It is notable that the second generation system uses engine oil to hydraulically modulate engine valve function. As a result, the system is dependent upon the quality of the oil in the engine. As anti-foaming agents in engine oil are depleted, air may become entrained or dissolve in the oil, delaying the timing of hydraulic control signals.
A redesigned cylinder head and manifold for improved air flow. Variable exhaust valve timing (the LW2 engine only had variable intake valve timing) Specially-developed fuel injectors. New pistons with pentroof-style centre-domes and valve eyelets for a higher compression ratio of 12.2:1 (compared to 10.2:1 for the dual fuel engine).
The two-valve arrangement is retained, though the titanium intake valves by Del West have grown to 2.2 in (56 mm) and sodium-filled exhaust valves are up to 1.61 in (41 mm). Peak output is 505 bhp (512 PS; 377 kW) at 6300 rpm (72.0 BHP/L) and 470 lb⋅ft (637 N⋅m) of torque at 4800 rpm with a 7000 rpm redline. [68]
Like the Tahoe, the Yukon will also feature an independent rear suspension, a 3.0-liter inline-six turbodiesel engine, and a top-shelf suspension option featuring air springs and magnetic-ride shocks, a standard 5.3-liter V-8, an optional 420 hp (313 kW) 6.2-liter V8, and a 10-speed automatic transmission that is standard across the lineup.
In 1968, the engine had the chrome covers, but without the Chevrolet name, connected to a PCV valve and a chrome 14 in × 3 in (355.6 mm × 76.2 mm) drop-base open-element air cleaner assembly fitted with a crankcase breather on a 780 cu ft/min (22 m 3 /min) vacuum secondary Holley 4-Bbl carburetor. 1969 Corvette and 1970 Z/28 engines were also ...
