seen it happen a bunch of times. Told ya!jimfulco said:My '72 Nova 350 was slapping the inside of the front cover at 50,000 miles. I had a '78 305 that just had a slight hesitation off-idle that I couldn't fix with carb or ignition work, but a new chain at ~70,000mi. fixed it right up. Stupid plastic parts!
Pretty dead on, there usually is no warning that I know of. Broken a few before, never had irratic timing, missing, or anything, was just driving along and it died. Turned the key, it turned about half over and then SCREEEAAACCCHHH!!! All over for that motor.troy-curt said:usually there is no warning. They don't break very often, just strip teeth off.
Wrencher said:Get a buddy to help ya, have them watch the rotor while you turn the crank one way until the rotor starts to move, mark the balancer and timing cover, turn back the opposite direction until the rotor moves again, mark and measure, 1/2" or less is acceptable.
If you open that engine up and see that the gears are made from nylon, could you PLEASE post some pics of the set? I would love to see a nylon set that made it to 180,000 miles. I want to see the condition of these gears, but more than likely they are all pot metal if they have made it that long. I never have seen an original set make it past 127,000 miles. No, I'm not trying to insult anyone, I really would like to see what a set of nylon gears looks like with 180,000 miles. Never seen one last that long.84_sportcoupe said:OMG!!! so what you are telling me that is the gears in my 84 305 with 187000 miles
never rebuilt, are made of nylonain: well looks like i need to get that replaced pronto.... man im glad i read this!! you guys rock...... that really explains a lot of problems ive been having... i should have replaced the whole timing set already but i only drive the car once or twice a month. so i wasn't in a huge hurry.
