Very good I am pleased to be able to help you and I hope that my little contribution will serve you and stay calm with your problem.
So you seem that the distribution you have not left well ready, if you changed the distribution strap, tensioning rollers and guides and also the water pump with its corresponding joint, you must control the tuning of the engine to see if the engine is well synchronized.
First you must put the first engine cylinder in the PMS control the engine synchronization marks and block the engine with something so that you do not move, in this section loosen the tensioner of the dentate belt of the distribution, marks the belt with a chalk in the direction of the belt to return it again and re -make the corresponding settings.
You can re -assemble the same dent strap again since it recently mounted and has a few kilometers. First cylinder you should not turn contrary to the direction of rotation of the engine because the tensioning value of the belt would be wrong and you are exposed to you can break it and skip a tooth of the distribution .... greetings and luck
