Hello was just looking for a litle advise please!!


Does piston slap get worse if you dont treat it , i mean if i dont rag my car around is my engine still gonna go bang like the chap at the garage said?
I took the car to another mechanic and he had two rally subaru's parked in his garage and he said the piston slap was not that bad and he would advise to run it on thicker oil for 500 miles????

thank u for any help!
