Yes, that tool is perfect, and the price is right. You must remove the distributor to use it, so mark the base so you can get it back in as it was. The rotor will turn as you lift it out because the gear on the bottom of the shaft will twist past the worm gear on the cam shaft. You must reverse that twist to get it back in exactly the same way. Or just time it from scratch, whatever is needed. Under the rotor are timing advance weights, never mind them since you will get the proper tool. And I said GENTLY! No need to stress the bolt or anything else. Let the oil soak for as long as it takes. Mine took weeks. After work every day I would go out to the garage and give it a go- eventually it budged. From then on it was more oil and more time, eventually loosening up all the way. But it seemed like forever at the time.
Thank you sir! I just ordered the tool. And I WILL be taking your advice! Slowly but surely it will come loose 🙂...
