Hi leutz I had a broken cylinder head gasket and had it replaced me. when I picked up the car and drove a while I had, after I filled up at the tank and then started to pick it up for the second time after, when giving gas a noise … sounds like a whirring that occurs in the lower turning zone but in all walks … I drove back to the workshop and the mechanic said that it might be due to the engine wash. he meant it’s the lighting machine and I’m supposed to see if the noise disappears tomorrow by itself, he said it might be because there’s still something wet … can you confirm his suspicions ? and assuming my lighting machine is gone, how expensive would it be if I had to eliminate the cause of the noise making ? thx jaX
