Tip for manually turning engine over (non-LSD, anyway)

This won't help anyone with a limited slip differential, sorry. You can stop reading now.

Last night I had my cam cover off to check valve clearances and the timing chain tension. Manuals always say to push the car in gear to turn the engine over; instead I decided to try something else. I jacked up the left rear wheel, put the car in fourth, and turned the rear wheel by hand. The engine turned. Much easier than pushing the car around an uneven gravel driveway at night. (Would have been even easier had I pulled the sparkplugs first.) I don't know if this is a common technique, but I'd never read about it, so I thought I'd pass it along.

Hi Bob,

A nice surprise is to find that the previous owner drilled & tapped the large front crank pulley nut, and added a 14 mm bolt. I can then easily turn the engine with a wrench (it also helps to have installed an electric fan and removed the original fan shrouds). This modification would be neat to do if you have your engine disassembled...

Another method was revealed when a buddy came by to watch me indexing the cams, and said he always turns the engine using the factory tool on the camshaft sprocket holes. This seemed to me to be kinda backwards, but it works. And, removing the spark plugs obviously makes the engine easier to turn.
