Hello everyone,
My name is Enrique(Spanish is my first language so some of the technical names might be a bit off, I'm sorry) , I'm currently fixing my Renault Clio 1.6V with my dad because the timing belt broke and some of the valves got bent sadly.
We took off everything, the timing belt, the cylinder head, replaced the bent valves, cleaned out the cylinder head, bought the things we need to put it back together but we have encountered a problem.
We put in the new head gasket and laid the Cylinder head on top of it, we replaced the bolts because one had stretched. We replaced them with 10.9 16mm bolts which don't have the same length of thread the original ones did, but maybe like half of the thread (is that okay?)
We bought a torque wrench and we proceeded to start tightening the bolts(following the instructions of 15ft-lb and 240 degrees afterwards) in the correct sequence(snakelike pattern) but we have stumbled onto a problem, after following the instructions, we see that the bolts all have different torques and I'm not sure but it doesn't make sense to me that they don't all reach similar torques.Some have 60ft-lb, some 50, some 55, and one cant even reach 50, it stays at 48, we tried giving that one a little more but we gave it almost half a turn more and it stays at 48ft-lb. We're not sure how to proceed because we don't want the car to break again. Please help and thank you in advance.
PS. if we untighten the bolts, does the head gasket get damaged? do we have to replace it?
