VANOS seal replacement on M50TU and M52,easy DIY

if your e36 has lost power between 3000-4500rpm the vanos seals are probably shot. the original rubber seals harden and leak oil pressure. replacement kits are about $60 online and the job takes 2 hours with basic tools. you dont even need to remove the timing chain. massive difference in midrange power once its done. every e36 over 150k needs this.
