i think the 1.6 ltr was only for some markets the engine i think it may be is! cyl head head with new bolts, 25nm +90 +90 +90 + 45 degrees the big end/conrod bearings 25nm +30 degrees thats if it a vauxhall/general motors engine. it may not be
Assume you are needing the cylinder head torque specs?
The head bolts are angular torqued and best practice is to fit new bolts and ensure all the female threads are thoroughly cleaned. I recommend greasing the bolt threads and washer faces.
The initial torque (following a spiral pattern) is 25 NM followed by angular movements of (degrees) 90 + 90 + 90 + 45
I generally start the engine and thoroughly warm up and allow it to cool before the final 45.
Head bolts are typically a Torque Angle to Yield specification, an example 100NM plus 75 to 100 Degrees of angle. You should be able to reuse the bolts, assuming that they have not been reused before. The bolts are plastically deformed when they go into yield, typically you can reuse them 1 to 2 more times. It is stated in the service manual to replace the bolts because it is never known how many times in the past they may have been retightened. So if you have a good history of the vehicle, and know that the head has not been removed, your pretty safe to reuse.
