Hi all just start by saying I'm loving my first vr it's a one owner low mileage (54k) 1996 5 door In mystic blue I Wanted to know if there is any modified parts regarding the timing chain/guides As I've seen a deutch car video stating the vr6 engine is very reliable once mods have been Made or parts changed for the timing chain and guides ???? Is this even true if it is then is it for obd1 and obd2 If any one can shed some light on this it would be appreciated as it's got me wondering about the factory fitted components and if there are parts to prevent future issues Cheers all
