Ive just about finished my R & D with a mk5 GT 1.4 and I have to say all these failures do not suprise me . Piston to bore clearances all over the places , really crap cylinder head casting , intake air temps through the roof at idle and absolutely no cool airflow over the engine on a hot day its only a matter of time before the engines grenade . I'll put up a post shortly on what Ive found and what Ive done and hopefully it all works (VW just throw another engine in so dont expect them to magically fix the issue!) .
