i think everyone just shits themselves with the Vanos cos they've heard they are common problems & expensive
vanos motors should be treated on there own merits; if it s noisy; stay away; if its not consider buying it
my friend had a 96k evo; FBMWSH and the vanos has never been changed and was quiet
for 3500 you wont find a very tidy evo IMO, the 3.0l you probably will
