If you use penetrating oil, does it cause the bolts to come loose after you reassemble them?

If you use penetrating oil to disassemble, does it cause the bolts to come loose after you reassemble them?    

 

Do you have to clean the parts somehow afterwards or just retighten to the proper torque and be done with it?

You can just clean the bolt with brake cleaner and apply some antiseize.

To lay a couple of false "old wives' tale" to rest, the use of thread lubricants like ARP Ultra Torque, penetrating fluids, or anti seize will never cause fasteners to come loose; the only thing that causes that is the fact they were not torqued to the correct specs in the first place, or were dry or unclean when they were assembled.  And before you ask, the use of any of these compounds will not cause over torqueing of the fasteners, but the assembly of dry or rusted fasteners will cause under torqueing and the potential for fasteners to come loose at a later time.

+1 on what JFP said.

Lots of "untruths" on the Internet about this.

I agree
