AOA zeeshan chain cover tu porana he milay ga or scrap market say he milay ge if u need I can inquire few people in scrap market here in lahore, for timing chain I would advise to update not only chain but complete Timing system so u can have peace in life for atleast 20~30 thousand kilometers.
or else if u change only timing chain then after few time the guides will be blown... then if u change only that then after some time the tentioner will be blown... and the loop continues.
the timing chain can only be sourced from thailand if u have some one there or AliExpress if u can live with chinese parts.
