SOURCE: on the 92 chevy lumina eurosport 3.1 push rods on

the euro sport is the same as the lumina base just with a body kit, stiffer suspension, and dual exhaust.

but on the 3.1 engine the pushrods are all the same length, but depending on the stroke each cylinder is on the pushrod may be in a different position.

you are assuming that every pushrod should be in the rest state. that is not true. if the cylinder you are installing the pushrod for is on the intake stroke when you install the intake valve pushrod and tighten the rocker arm nut the valve will procede to open like it should be open for the intake stroke.

this is normal and its nothing wrong with it.

SOURCE: how tight to tighten valve cover

I highly recommend you buy a Hanes/Chilton manual for your make and model of car. The manual will tell you inch pounds and torque sequence for tightening the vale cover back on. Usually the sequence works from the center and works it way to the outside bolts. Please rate this reply if you found this helpful.

SOURCE: how tight should my valve cover be tighten downed

All you have to do is get a 3/8 ratchet or a wrench and just snug the bolts up to about 10 ft.lbs.of torque then go back and do all the bolts again to about 15 ft.lbs. of torque and you should be good to go.Basically 15ft.lbs. is just using one hand and snug it down with light pull of ratchet.

Install push rods on a 6v71 detroit diesel


Your talking valves , not rods. Yes they are a pain. The valves have to be flat and tight against the head, then compress the spring and cap to get the keepers in. I modified large welding clamps to do this.

I'm having problems getting the rocker arm assemble to go back on and tighten down with out locking the cam where it will not turn at all and that is with bolts finger tight


When the rocker arm assembly is tightened down the lobes on the cam will be pushing the lifters which will put force on the push rods which will rotate the rockers which will open the valves against the valve springs. And,,,
That will create frictional resistance in the entire system, And,,,
Any rotation of the cam will require valve springs to compress.
I know that my old fingers would not contemplate trying to rotate it.
Cheers

Blown Head Gasket repair - How do I set the valves correctly? DO I need to turn the crank shaft or just tighten to remove LASH?


what type of engine are you working on. On GM small blocks you will need to turn the crank to zero on the timing tab, which will bring #1 piston to the top ( you can remove #1 plug and verify #1 piston is at the top) Then you will need to turn the rocker arm nut on the intake valves until the push rod is just finger tight, (turn the push rod as you are tightening the nut) and then turn it 3/4 of a turn. once you have done the intake valves you need to rotate the crank 180 degrees to bring up the exhaust valves and do the same procedure to them. If it is the valve lash it should start. Hope this helps, this will probably work on most cars.

Install cylinder head bolts finger-tight. New cylinder head bolts are recommended due to stretch of the old bolts.
Tighten bolts in sequence, tighten the long bolts to 46 ft. lbs. (63 Nm) plue 90 degrees. Tighten the short bolts to 43 ft. lbs. (58 Nm)


Install pushrode and rocker arms and rocker arm nuts. Tighten nuts to 22 ft. lbs. (30 Nm).


Install valve cover and tighten bolts to 89 inch lbs. (10 Nm).

are you asking , how to set rockers ?

chapter 9 page 27
------------------text fsm---------------------
INSPECTION
Inspect the pivot surface area of each rocker arm.
Replace any that are scuffed, pitted, cracked or
excessively worn.
Inspect the valve stem tip contact surface of each
rocker arm and replace any rocker arm that is deeply
pitted.
Inspect each push rod end for excessive wear and
replace as required. If any push rod is excessively
worn because of lack of oil, replace it and inspect the
corresponding hydraulic tappet for excessive wear.
Inspect the push rods for straightness by rolling
them on a flat surface or by shining a light between
the push rod and the flat surface.
A wear pattern along the length of the push rod is
not normal. Inspect the engine cylinder head for
obstruction if this condition exists.
INSTALLATION
NOTE: This procedure can be done with the engine
in or out of the vehicle.
(1) Lubricate the ball ends of the push rods with
Mopart Engine Oil Supplement, or equivalent and
install push rods in their original locations. Ensure
that the bottom end of each push rod is centered in
the tappet plunger cap seat.
(2) Using Mopart Engine Oil Supplement, or
equivalent, lubricate the area of the rocker arm that
the pivot contacts. Install rocker arms, pivots and
bridge above each cylinder in their originally position
(Fig. 23).
(3) Loosely install the capscrews through each
bridge.
(4) At each bridge, tighten the capscrews alternately,
one turn at a time, to avoid damaging the
bridge. Tighten the capscrews to 28 N·m (21 ft. lbs.)
torque.
(5) Install the engine cylinder head cover (Refer to
9 - ENGINE/CYLINDER HEAD/CYLINDER HEAD
COVER(S) - INSTALLATION).

The roller rockers broke. I am not sure why but I need to know how to replace them


You didn't say what kind of car is, but but if they have a hex nut with Allen screw inside it. Remove the nut and screw the screw back. Remove their old rocker and put the new one on. Put the nut on but not too tight. Now turn the motor slowly until the other valve for that cylinder opens. Now a just and nut down. If it's a hydraulic tighten the nut down snug thing go 3/4 turn more. If its mechanical use a feeler gauge and go with the proper clearance. Then tighten the Allen screw back down very tight. Try to figure out what went wrong. Because it could happen again. Remove the push rods and roll them on a flat surface to see if they are straight don't use bent push rods. Then check for spring bind, with the valve all the way open there should be no spring bind use a feeler gauge to check for this. Also look at the rocker to make sure it's not restricted in any way, also no interference with the pushrod. Without seeing it that's about the best I can do. Good luck.

Need head bolt,intake upper and lower and rocker arm torque lbs.


Head bolts--------- 22 ft lbs.
Intake upper------ 18 ft lbs.
Intake lower------- 10 ft lbs. Tighten vertical bolts first, the diagonal bolts, failure to do this will result in an oil leak.
As far as the rocker arm bolts, they have to be adjusted with the valves closed, tighten down just enough to turn the push rods with your fingers with slight tension.
This is out of a Technical Specifications Manual.
