I would use the tabbed washers : they don't affect the torque reading as once the nut is torqued, they bend easily and just lock the nut into place. Loctite - if available - may not always be effective if the parts are not clean. Tabs work if the parts are clean or dirty.
This is essentially looking for binding. It has nothing to do with how long it will spin on its own inertia.
As you progress thru the assembly, it should turn with little effort to ensure there is no binding. Some instructions will even give you torque specs for each piston added.
If it does not turn easily, then something may be installed ...
After a full rebuild, with every part lubed as it should be I would not expect to be able to spin any 4+ cylinder engine over freely by hand.
If say you we're turning it at the flywheel, or the engine only had the crank installed then yes you should be able to turn it over quite easily.. but with pistons installed and trying to spin it say via the crank ...
Rod Knock Causes
Rod knock is when the hydrodynamic layer of oil between a hydrostatic bearing and a journal is being broken during the 4 cycle combustion process. Additionally, rod knock occurs with ball bearings in a connecting rod if there is too much clearance between ball bearings and races.
You can get rod knock frequently in conjunction with the ...
A very accurate way to mic your rod and main journals is to use a telescoping gauge set. They looks something like this set:
The ends of the "T" are spring loaded and the end at the base of the "T" twists to lock the head in place to set the distance. They work something like this for the main bearings:
Install all of your main bearings in the appropriate ...
Solar Mike is correct.
The known terminology to anyone with shop experience will call it a "sway bar end link"
it provides stability and attempts to keep your tires planted to the pavement (which is where you want them planted, not in the air).
The most common name is "sway bar end link"
if you are looking to replace them, be sure to get new hardware (nuts) ...
