Buon pomeriggio.
Amici, vorrei consultare quali sono le cause che possono causare una valvola di fuga o di ammissione ???
On the other hand, a mechanic tells me, that after doing a complete service to a camera, where the valve guides and their approaches, and the contact surface with the block, the latter if it is rectified too much, can cause it to cause the engine to be up Turn off because it folds the valves, since the camera was very low, and the pistons are demanded more, so they make more route and come to collide with the valve, is this true ???
Grazie e saluti !!!
