Fig. 8 Timing Mark Alignment

Remove Front Cover.
Remove crankshaft oil slinger.
Crank engine until 0.0 marks on sprockets are in alignment, Fig. 8.
Remove three camshaft to sprocket bolts.
Remove camshaft sprocket and timing chain together. Sprocket is a light press fit on camshaft for approximately 1/8 inch. If sprocket does not come off easily, a light blow with a plastic hammer on the lower edge of the sprocket should dislodge it.
If crankshaft sprocket is to be replaced, remove it with a gear puller. Install new sprocket, aligning key and keyway.
Install chain onto camshaft sprocket. Hold sprocket with chain hanging vertically, then align marks on sprockets as shown, Fig. 8. The valve timing marks shown in Fig. 8 do not indicate TDC compression stroke for No. 1 cylinder, which is used during distributor installation. If distributor was removed, install timing chain and sprockets, aligning timing marks, Fig. 8, then rotate engine until No. 1 cylinder is on compression and camshaft timing mark is 180 degrees from valve timing position shown in Fig. 8.
Align dowel in camshaft with dowel hole in sprocket and install sprocket on camshaft. Do not attempt to drive sprocket on camshaft, as welch plug at rear of engine can be dislodged.
Draw sprocket onto camshaft, using the three mounting bolts. Tighten to specifications.
Lubricate timing chain and install cover.

Customer replied 678 days and 13 hours ago.

I should have ask this Q first. What r some early warning signs that a chain is in need of replacement?

Expert: Chevy expert replied 678 days and 13 hours ago.

If the timing chain is loose the timing could be wrong but most commonly you would hear a taping noise or a ticking on the timing cover this would be the chain slapping on the cover

Customer replied 678 days and 13 hours ago.

Please answer, correct way to re-time this engine.
