    73 Eldo Timing Chain

    I recently aquired a 1973 Eldorado convertible that is not running, previous owner's mechanic said the timing chain is bad. I pulled the balancer, hub, timing cover etc. I'm trying to check the timing marks before I remove the old timing set but I can't find any marks on either gear. The cam gear is missing a little of the plastic or nylon. I did order the roller set with 3 keyways. Any help with diagnosis would be greatly appreciated!

    A 1973 motor has small chamber heads.. If this motor jumped a tooth or two on the timing chain the pistons will hit the valves.. So there is a good chance you need to take the heads off and change some valves...If you want to test for bent valves , take off the rockerarms and put compressed air to the sparkplug holes.. you need the correct fittings and hose...If the valves are bent you will hear the air coming out the tailpipe or carb.. If the valves are good you will only hear air go by the rings and come out the crankcase..
