Ok, point taken!yes but why?
That would be something you do if it was broken or you had the engine apart for a rebuild and thought the spring was weak..
In your case (your engine certainly doesn't look clapped out!) I would just do the simple safe chain tension method I mentioned: plugs out, loosen nut, roll the car in gear, tighten nut...forget about it for another 3 years!
Now if your engine sounds like a bag of bolts, then OK investigate further and take it all apart.

Now, i just came from the garage where i wanted to change the brake fluid, but when my wife pushed the brake pedal a gurgling sound was heard. I traced it to the hole under the cast iron thingie where all brake pipes go from. Just after the joint to the main brake cylinder or what it's called. When she pushes the pedal it gurgles and comes out fluid from the hole. Is it the main brake cylinder or what could be wrong? Never had this problem on a car.
