Gen3 main cap bolts

[63SplitWindow]

As part of the job replacing the oil pan and pickup for the Gen 3 swap into an A body, it is necessary to remove and swap out 2 of the main cap bolts for the new windage tray. My question is, do the new torque to yield bolts require lube? What is recommended if I do?
I am only replacing 2 bolts on 2 different main caps. I think I can do that without disturbing the other 2 bolts on the maincaps.
Thanks,
Bill

...torque to yield bolts...

FYI, they aren't torque to yield. The tightening procedure uses a torque to angle process, but that doesn't mean the bolts are torque to yield.

This is talking about head bolts, but it's the same idea.

I will check this out.....Thanks Dion

Here's what I found in the 2015-18 Charger FSM I have:

Hopefully you can read that.

Here is a clip of the torque specs. Note that while it does say new fasteners must be used for rods and oil pan bolts, it doesn't say that for the main cap bolts.

Note that the above info is from the 6.2 section of the FSM. The 5.7 shows different specs and it seemed like you were working with a HC motor so I made sure to clip info from that section.

Yes....I am working with a HC motor.
I was only looking to replace the oil pan....wasn't looking to open the bottom end....lol

I understand. FWIW, I wouldn't call moving a couple bolts around as "opening up" the bottom end.
