One question.....how often have you used a torque wrench on engine re-assembly and on what bolts/nuts.......?
Well prior to the course I only used my own torque wrench on the wheel nuts. however since the course i've used it on everything when putting the engine back..
e.g. on this assessment which was just top end we had torques for:
inlet manifold
exhaust manifold
coil pack retaining bolts
head bolts (inc. head correct tightening sequence)
cam shafts shells (inc. tightening sequence)
valve cover
cant think of any more we used.
the head bolts were torqued in stages... however cos they're stretch bolts and they've been undone/re-tightened many times we just did the first two stages and missed out the final ''angle tightening''.
