checking for bent push rods question
Hi all
If I wanted to remove my rockers to check for bent push rods, is it as simple as removing them and then just torken them back on? Is the tork setting 22 ft/pounds? Any thing I should do while I am doing this?
Thanks
Bud

You should torque them using the sequence indicated in the manual. I've pasted part of it below:
Install the rocker arms and bolts. DO NOT tighten the rocker arm bolts at this time.
1) Rotate the crankshaft until the number one piston is at top dead center (TDC) of the compression stroke. In this position, cylinder number one rocker arms will be off lobe lift, and the crankshaft sprocket key will be at the 1:30 position.
The engine firing order is 1,8,7,2,6,5,4,3. Cylinders 1,3,5, and 7 are left bank. Cylinders 2,4,6, and 8 are right bank.
2) With the engine in the number one firing position, tighten the following valve rocker arm bolts:
Tighten the exhaust valve rocker arm bolts 1,2,7, and 8 to 30 N·m (22 lb ft).
Tighten the intake valve rocker arm bolts 1,3,4, and 5 to 30 N·m (22 lb ft).
3) Rotate the crankshaft 360 degrees.
4) Tighten the following valve rocker arm bolts:
Tighten the exhaust valve rocker arm bolts 3,4,5, and 6 to 30 N·m (22 lb ft).
Tighten the intake valve rocker arm bolts 2,6,7, and 8 to 30 N·m (22 lb ft).
To more easily rotate the engine with the steering rack still in place, I modified a 24 mm socket to fit the crank pulley bolt so that I could use a wrench to turn it.
