Hello, have a problem with my Galant E70. The hydro-punch clacks. Actually nothing special about 170 000 km can happen. Now the thing is: If the car is warm, then it’s gone. If there is little oil in the car, it gets louder. So is there actually the hydro-push broken or is it something else (possibly oil pump?) and can help there possibly an oil sludge flushing? Would be much cheaper than having the hydro-push switch for the V6… Am for everyone Hint grateful!
