Has anyone had any experiences with engine flushes on a Cupra , I have Noisey tappets and it’s driving me crazy, I’ve just bought myself 2 forte injector cleaners and 2 lots of petrol treatment bottles , the injector cleaners work very very well. So I am probably going to flush the engine in a few days with the forte brand , the car has been well maintained , regular oil changes but don’t think it ever has been flushed , 90,000 on the car now , just abit cautious as people say it can block up feed lines and so on..
