When to replace the cam chain.
Like the title says. I cant find a definitive answer on whether this needs to be changed or not, My rigs got 140,000 on it ( this was/ is my first vehicle, so a few of those were hard miles...) but make no noises or anything like that. Theres a little slack in the chain itself, but since theres no tensioner, there has to be a little play, right? If it does have to be done, ill do the gear to. Is the crank gear removeable, it looks like a real PITA to get off, so it may stay on just cause. Any ideas?
