Logic tells me torque to yield bolts (additional rotation after torque to a spec) have to be replaced.
Can someone please confirm the only bolts on the engine which should be replaced are
Head bolts First torque to 40 N•m (30 lbf•in); Then tighten screws turning an additional 120° rotation with a torque angle gauge and finish tightening with a 90° rotation.
Main bolts 40 N•m (29 lbf•ft) following sequence 1 to 8 and then to 55 N•m (41 lbf•ft)
Rocker shaft bolts Torque screws at first to 10 N•m (89 lbf•in); Torque screws to 20 N•m (177 lbf•in).; Finish tightening screws turning an additional 90° rotation with a torque angle gauge.
Connecting rod-bolts – Install screws and torque to 45 N•m (33 lbf•ft). Do not apply any thread locker product.– Finish tightening the screws with an additional 90° turn using an angle torque wrench
I am also replacing cam sprocket and flywheel bolts while apart.
Also all rings, bearings, chain and chain guides.
Tear down is to replace head assembly (with a 2017) and piston.
Thank you!
