i was wondering if i had to actually loosen the crank bolt to turn the engine to TDC to do a valve adjustment, or what? i know there's a way by putting the car in fifth and rolling it or something, but i'd rather do it the real way. the problem is that the torque specs for the crank bolt is 178 lb/ft and my torque wrench only goes up to 150 anyone w/ experience help me out

i think all you'll need is a long rachet with a 19mm socket to turn the crankshaft.

You don't have to loosen the bolt to turn the crank. Just turn it with a breaker bar. Only turn it counterclockwise.

oh ok. well i know there is a place under the driver's side fenderwall where you can reach it, but im just making sure i don't ahve to loosen the b!tch. anyone else?

Why would you loosen it? You don't need to. Just take the 19mm socket and turn it counterclockwise (ONLY counterclockwise).

How would you damage anything by turning it clockwise?

71dsp

You -probably- won't damage anything, but the cams and every other moving part in the engine are made to turn counterclockwise (the direction of engine rotation), plus all of the surfaces have worn together by the engine rotating countclockwise, so it's a bad idea to rotate it in the opposite direction.

Easiest method is to jack one drive wheel off the ground, put the car in 4th gear, then turn the wheel that's up off the ground- you'll turn the engine over as you do so.

I've turned it clockwise about 1/4 of a turn. It was my first time turning the crank. My engine runs completely normal, so I assume it's ok.

Remember, pull your spark plugs out. It's damn near impossible to turn it with the plugs in.

Marsh

I've turned it clockwise many times. It won't hurt the engine unless you were to do it at some measurable rpm. But yes, you "should" turn it CCW.
