he is gonna need alot more to do rings than a workshop manual...
its one of these jobs do i pay som1 a mint to fix it
do i attemp to fix it myself by buying special tools and parts that will end up costing alot of time and money
or do i do the cheapest option wait till the last minute take all the good parts off the motor and buy a second hand one for a few hundred dollars
you will be best off i can tell you now to just buy a second hand motor with a 3 month warrantee
taking the pistons out is the last job an inexperienced person should be attempting
and if you do buy a second hand motor and you want to learn or do up your motor its out of the car just waiting for you to start throwing money at it.
