How to replace the timing chain and sprockets on Buick Regal?

To replace the Timing Chain and the sprockets, start by removing the engine's front cover. Get as close as possible with the sprocket timing marks, right after the Timing Chain dampener and the bolt camshaft sprocket. If camshaft sprocket and Timing Chain comes off with difficulty, a gentle blow appertaining to the bottom side of the sprocket using a plastic mallet may be helpful to free it. Next, you have to disassemble the Crankshaft sprocket and if needed, the balance shaft drive gear to reach the camshaft thrust plate and its bolts. Check out all components for wear or damage then clean them. If the Piston has been moved either at the engine assembly plant or while the engine was installed, turn the Crankshaft, so, the number one Piston is at the top dead center and align the camshaft to have its timing mark facing straight down using the sprocket temporarily installed. For installing, if needed install balance shaft driven gear and lock concerning the balance shaft end so that it won't turn while install balance shaft driven gear bolt, torque it to 22 nm (16 ft. Lbs.) using electronic torque angle meter (J 36660-A) twist bolt 70 more degrees. Mount up the camshaft thrust plate with its bolts and tighten to 15 nm (11 ft. Lbs.), followed by the balance shaft drive gear. Ensure the timing marks are as close together as possible on the balance shaft drive gear and the balance shaft driven gear and align the timing marks, then install the Crankshaft sprocket/Timing Chain/sprocket. Replace the camshaft sprocket bolt, tightening the bolt to 100 nm (74 ft. Lbs) by using electronic torque angle meter (J 36660-A) to turn the bolt further 90 degrees. Lastly, fit the Timing Chain dampener and tighten the bolt to 22 nm (16 ft. Lbs), turn the engine two times to verify the alignment of the timing marks and fit the front cover of the engine.

The Timing Chain in Buick Regal vehicles is responsible for the synchronization of the rotation of the camshaft with the crankshaft so as to have proper setting of the valves to support the high performing engines. Sitting close to the front of the engine and made of metal this chain must be lubricated for smooth running and is a part often associated with higher displacement engines. Metal timing chains have been replacing rubber timing belts since the 1990s due to their durability and the central advantage of the long intervals of their use. Timing chains as a form of providing timing accuracy are generally good, but they do have problems springing from failures of the lubrication of chains or breakdown of the tensioner and chain sprockets that will usually be indicated by a rattling noise coming from the engine. The drive chain most commonly used in pushrod engines is a short chain drive since it can sustain torque reversals better than gear drives and is more noiseless as well as durable.
