Hello,
audi 80 (1993 uk) 1.9Tdi
i am about to buy the necessary parts for a timing belt replacement
job and i am a bit confused about some parts.

parts required;
timing belt
belt tensioner
water pump and seal
front crank seal (is this the proper name?)
i read about a cam seal (is this required or is it the same as the
crank seal?)

idler pulley, idler roller - are these the same part? and are the
required in addition to the belt tensioner?

i know there are lots of posts about timing belts, and people will
probably be pissed at another novice posting silly questions, but all
relevant help will be appreciated.

thanks
richard
