Frequently Asked Questions — Engine Repair in Hyderabad
When is cylinder sleeving needed?
Sleeving is needed when cylinders are worn beyond maximum oversize, have severe damage, or when restoring to original bore size is required for specific applications.
Can cracked engine blocks be repaired?
Yes, most cracks can be repaired through welding, pinning, or metal stitching. Location and severity determine the best repair method.
How much can cylinders be bored over?
Most engines allow 0.020-0.040 inch (0.5-1.0mm) overbore. We measure wall thickness ultrasonically to ensure adequate material remains.
Is block repair worth it vs replacement?
Block repair is usually 30-50% the cost of replacement and maintains your original engine. For most applications, it is the economical choice.
