Hello i have a imported 98 sti which has piston slap, however a subaru expert said it was nothing to worry about as was minor slap and it is comman with my type of car!!
One thing he advised was possibley putting thicker oil in the car which may solve the problem??does anyone have the same problem and putting thicker oil a good idea?
Have tried slick 50 and also changed the left hand side tappets,thanks for any advise!
