hello my project is the following my well-known has an audi 80 1.8 s that already has 250000km on it to rebuild on a gas system. have here another golf 3 motor lying on it only 135000km the mkb of it is adz. since it is not the same mkb, here comes my question 1.8 are 1.8 but can I simply remove the old motor components to the new motor without changing any holders now. also because at audi the motor is in the air and at vw cross-in. so just old for new exchange. good the gas plant must be entered by the tüv and just that is clear, but to change the thing still holds that makes no sense. about help from you I am grateful
