1998 Chevrolet Express 3500 Q&A
1998 Chevrolet Express 3500 Question: timing
When changing timing chains shop manual says to position camshaft sprocket marks at 12"00 and crankshaft sprocket marks at 12"00 then rotate crankshaft 360 or 1 turn. This places the camshaft sprocket mark at 6"00 and the crankshaft sprocket mark again is back to 12"00.Thus the 2 marks are now oposite each other at 6'00 and 12"00,which is where they should be at the end of the timing chain installation.Question is do you stab the distributor pointing the rotor to #1 on the cap while the marks are at 12"00 /12"00 or at 6"00/12"00.I would think stabbing it at 12/12 because that represents #1 compression stroke,but ya never know so hip me please. - ffasteddie
traditionally, 350 timing chains are installed with 12 on the crank and 6 on the cam for compression stroke. follow the procedure as outlined. if you want to be sure, pull a valve cover and make sure of the stroke by the position of the valves. Roy - mastertech6371
