...but 3 degrees each way is more than you might think, especially with a long wrench. I would still retorque them if I didn`t think they were done to spec.

It's a pretty close spec ... 50 +/- 3
You obviously don't eye ball it.
Is there a special gauge for this I can buy.
I don't want one main cap different from the rest of em.... should I break loose and re-tighten all of them ?

Thanks for the help.
Don't want any slip ups on this.
Wrestling with the cost of replacing timing chain and rails as well while I have it out. I haven't opened it up to inspect yet. Not sure I want to go there but.......


Step two is to turn the bolts an additional 50 degrees. Torque angle is another way of specifying torque which is intended to eliminate variations in friction of the threads. It has nothing to do with offset wrenches, adaptors, etc.

On the CD is 16 +/- 2 ft/lbs
Torque angle 50 +/- 3 degrees

Are they saying to use this figure at 50 degrees ??
This seems way too low... at that angle.
Besides on the main caps it's possible to always be straight on the bolt.

I'm still puzzled.


"Torque Angle" in conjunction to the stated torque value.
Is the offset of the torque wrench to the centerline of the normal torque wrench.

Many places you can not use straight torquewrench. You have to use and offset connector. Almost the same as a extention but for sideways offset.

A one inch offset at 45 degree should increase the torque needed to get the same as 90 degree offset.

This is sometimes used to reference driveline offset too, principals are the same.
