How do I set the cam on a 4hg1 Isuzu?

To set the cam on a 4HG1 Isuzu engine, first ensure that the engine is at top dead center (TDC) on the compression stroke for cylinder one. Align the timing marks on the camshaft and crankshaft pulleys according to the manufacturer's specifications. Once aligned, securely tighten the camshaft bolts and check the timing again to ensure proper alignment. Finally, reassemble any removed components and verify that the engine runs smoothly.
