Why do single cam bows have timing marks?

Manufacturers intend for their single cams to rotate a certain amount, from a specific starting point. If that rotation is off, then the cam’s performance will be off. Single-cam bows usually have a timing mark that will let you see if the cam is properly timed. Often, it’s a hole in the cam.

What should I do if my timing cover is taken off?

Anytime you take a timing cover off, take a quick look at the timing marks, then check for excessive backlash, gear or sprocket wear and belt or chain play. Also check for clogged gear or chain lube drains. High-mileage engines may need a new chain, gears or belt just as a safeguard, before timing failure sets in.

What makes the timing chain rattle on a Ford Explorer?

Some of the early engines up through 2002 in the Ranger and Explorer have had a timing chain rattle problem due to the poor design of the original teflon chain guides. The noise is most noticeable when a cold engine is first started, and is usually loudest from 2400 to 3000 rpm.

How do you find the timing mark on a Mustang?

You can stick a small screwdriver or bamboo skewer through the spark plug hole and feel the piston. You can then make small movements of the crankshaft and determine if the piston is all the way at the top. Once the #1 piston is at the top, look for the TDC mark on the balancer – that’s the side where your timing pointer goes.

Where are the timing marks on a Ford 302?

Ford used several different timing pointer/harmonic balance sets on 302s depending on the year and what side the water pump inlet (lower radiator hose) was on. What side is the lower radiator hose on on your engine? Do you now what year the engine is? Here’s a picture of the “cast-in” pointer found on engines with a passenger-side-inlet water pump.

Where is the timing light on a 94-95 Mustang?

On 94-95’s its near the passenger side strut tower (B).
