hi,i have a seat ibiza 1.4 aud engine 8v 2001 and ive heard lots of stories where seat ibizas suffer from piston slap causing a loud engine knock.My car does have a bit of a knock fom cold and goes when warm, is this one of the affected engines?It doesnt seem to be using oil or lacking power and has started all the time i have had it.Do these engines normally make a bit of noise or more of a characteristic?It isnt really loud at the moment.cheers.
