hello all, new to the forum but not Volvo. I have a strange issue I need help working out. 02 s60 2.4 turbo auto fwd 57,000 KM
start it up in the morning and let it warm up everything sounds perfect rev or power brake everything sounds and functions perfect, as soon as I start driving its still normal until I accelerate then it sounds like piston slap or rattling in the engine until engine is heat soaked but not all the time even, I have replaced plugs, timing belt, engine mounts (all) and running good oil and fuel with Lucas fuel treatment. everything came off looking good and went on good. the car is in like new condition except for the noise. I read vvt can make some noise so I am replacing the solenoid gasket with the updated filter built into the gasket and cleaning everything up.
any kind of suggestions would be so helpful, I see people had similar issues but no direction for a repair. thank you to everyone.
