Timing Chain broke, trying to get the new one on
How do you replace a timing Chain? on 1994 GMC Sonoma
If the timing chain broke there is a distinct possibility that more internal damage may have occurred (bent valves, perhaps even piston damage). There is a company that independent auto repair shops buy their information from that the same information inexpensively to do it yourselfers. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate http://bit.ly/AllData_Repair_Manuals_Online This is going to be the best resource if you are doing the work yourself.
