When should I change my timing chain?

[jim_howard_pdx]

Most tech bulletins say to replace your timing chain a minimum of every 100,000 miles.

I bought a Cloyes true roller street set up. It allows you to run the cam straight up, 4 degrees advanced (more low torque) or 4 degrees retarded ( more horsepower at high rpms). $59.00.

Now I just replace the chain anytime the timing cover comes off. Chains run $17.95.

On any chain there is the side from the crank to the cam, it should have NO SLACK to very minimal slack, on the back side there will often be about 1/2 inch of slack. This is normal.

If the chain breaks, the valves stay open, the pistons collide, things bend and break.......NO FUN.

$17.95 every 100,000 miles is like an oil change.....

Just something to think about.....
