broken timing chain now Ticking noise need help

undercover50 said:

my timing chain broke on tuesday and broke my timing chain cover. I was some how able to drive the car 14 miles home . The car ran smooth all the way home. I kept my eye on the oil pressure ad it was fine. Once I turned the car off and tried to start it back up i heard the timming chain rip completley off the gear. After the timming chain was replaced I started hearing this loud ticking noise from my car. what could be causing this ticking sound. I had just had a cam installed along with new lifters



Thanks for the help

im certainly no expert here. however, i dont see how the timing chain breaking bad enough to hurt the cover would allow you to drive at all. if it broke, when you cranked the motor, pistons and valves would have been introduced (these are interferance motors, no?). if it had only jumped a tooth, it would not gouge the cover, and would run poopey, right??

i could be totally wrong, but it doesnt add up. sorry to offer no real help, but that is what occurred to me. good luck.

Pull the valve covers and check for a bent pushrod. They are the weakest part in the valve train. You could also have a bent rocker or a bent valve. In the future if you ever suspect a problem with the timing chain don't even try to start the car. You can bend up a lot of expensive valve train components.

The valves always open and close when the piston is either headed up or down. The valves should never be wide open when the piston is at the top (TDC). When the chain slips it allows the cam to get out of time with the crankshaft. If it allows the cam timing to get off far enough the piston can come up when a valve is wide open. When that happens the piston hits the valve and something bends. All you need to do now is find out what is bent.
