Austin mini 850 escape and windshield escape

Hello, I have a mini 850, the escape flange with the collector, is bitterness of my life. I changed the flange, put pasta for escape assembly, everything clean. And it still has a gas leak, and the air filter dirties me at a few kilometers. Any idea? Also say that the cone of the tube and the collector output have no deformation.
On the other hand, the windshield wiper has never worked well. Without strength, and where you feel like it. I disassembled the motor, cleaned it and put a new induced. Since the inducting coil has continuity and nough derivations. The brushes are whole, without scratches, there is no damaged cable in the engine. The varillage works soft (a kind of zipper. But it still does not have strength. Thank you very much. Greetings, Joan

It is strange that if everything is so correct, you have escape. It is likely to have a small deformation. Make all repairs you did without removing the set and worked without good visibility. Now the ideal would be that you take away Elalescape and multiple once armed it to see if they are really twin. Maybe you should perform the outsourcing that outside will be more visible. You could also take into account that the escape system is saturated and that helps to occur due to the most weak points.
Regarding the window, you also say you have reviewed all the point and without a ebmbargo does not work. If the winding is fine the brushes or coals also the collector also, the zipper and gears as well, do not meet much to say that if you need to say in which state are all the bushings and/or engine bears and gears. Greetings and luck

Hello, thanks for your answer. I will look at how you say the escape and see if there is something that escapes me, as you say for lack of good vision. As for the windshield wiper, he wears bronze caps, and apparently they are not spent. I only have to check if enough voltage arrives when acting on the switch. I hope to give the ruling soon. Thank you very much again. greetings. Joan
