How to align the timing chain on the Buick GL8 3.0 engine?
1 Answers
The camshaft gear also has three marks: two groove marks aligned with the cylinder head plane, and the dot on the gear aligned with the black chain link on the chain. The TDC mark on the crankshaft gear should align with the mark on the oil pump. The chain has differently colored chain links. First, rotate the crankshaft to the top dead center of the first cylinder piston. You will see alignment marks on the timing gears.
