keensert is very similar to the system CATERPILLAR Technicians use to repair damaged threads.You have a cat dealer in POOLE.
Ask them the avaibility and prices for the 3/8UNC thread repair kit reference
9S-3618 , this kit comes with 6 inserts, so you can repair more damaged threads....
Don't use your engine with this damaged threads, you will blow your cylinderhead gasket very fast, and add some distortions to your cylinder block surface.
Usualy, the threads Inside your XR2 block are 3/8UNC in size, better to check first to make any order of kit anyway.
hope that helps
