I have an 87 F-150. i noticed coolant leacking from the front of the engine. so i proceeded to replace the waterpump and thermostat. Of coarse murfee allways finds me and the bolts broke off, so i had to remove the timming cover. and the timming chain and sprockets where about done. so i replaced them. when i got it all back together and went to crank it the chain jumped off the sprocket. i figured it was just my dumb luck and replace the chain and sprockets again. it jumped off agian please help
Thanks :fraz:

What timing chain did you replace it with? How much slack was there in the new chain after you installed it? When you put the chain on was it a firm fit to get on, my last one took a bit of leveraging to get on.

not sure what brand the new timming sets where. the new chains went on tight had to put a little elbow grease to get it on. no slack in the chain after it was installed

thanks

For something like that to happen surely;

a) cam bolt was loose? or
b) dowel in the camshaft snapped?

I've seen this happen in Holden 253/308's. Sometimes they got away with it.
