Rebuilding a 3.1l v6. I removed all pushrods making sure to keep them in correct order. What do i tighten them to?I've read that you want to spin each one by hand until you can no longer spin them freely, then go 1/2 turn extra. My question is, do i need to put wrench on harmonic balancer and turn engine over while i am doing this? How to find exhaust/intake stroke? Haven't moved anything yet, aside from new head gasket/lim. Can i just drop them in and tighten as described above?

 

There's no need to turn the crankshaft. Coat the friction surfaces with assembly lube. Tighten the rocker arm bolts to 89 lb-in (10 N·m) plus 30 degrees.

 

cOOL, that's what i thought, thanxs for the reply and clarification, you sir are awesome!

 

think i found the problem with the misfire cylinder #3, when i removed the valve assembly and peaked underneath, i found the spark plug was not spun in all the way! i had replaced the plugs in the past and thought it was seated correctly however, upon applying more pressure,and carb/choke cleaner/pb blaster/ i was able to spin it in until it was properly seated. No, it was not stripped or cross threaded / it was rusted/frozen threads i believe to be causing the misfire.Installed new head gaskets,LIM gaskets.have to put fuel rail-injectors/upper plenum in next day off. Have to do oil change. should be done(crosses fingers)<a href="http://twitpic.com/8vv9p1" title="New Multimedia Message on Twitpic"><img src="http://twitpic.com/show/thumb/8vv9p1.jpg" width="150" height="150" alt="New Multimedia Message on Twitpic"></a> uhhmmm ouch!!!

 

I can't say I've ever had a problem installing. My problem always has been getting them out. Did you use anti-seize compound or did the spark plug maker say not to use it?

 

-This car was used an abused. 250,000+ miles on it, engine was replaced.I'm thinking the backwoods grease monkey i bought it from just spun it in, felt it stop, and said "o.k." (however, i did the exact same thing, when trying to iron out the misfire problem earlier, -so i am no better.) Upon removing the valve assembly it was very easy to see it was not spun in all the way. Yes, i have reassembled with anti-seize.
-When i have trouble removing spark plugs, I add an extension(when it will fit) then take a hammer, and tap on the end of the extension. I will then put the wrench on, and again with the hammer, tapping this time on the end of the wrench loosening it,don't do this with a crappy wrench, as it will strip out eventually and become worthless. 9times outta/10 it works for me like a charm. Also a good blast of penetrating oil. Impact guns,or pneumatic tools ,are considered an absolute last resort, as it is very sketchy that you may strip it out just trying to remove it.When i get desperate, such as set-screws on bearing collars, or sprockets, or exhaust pipe, i heat the buggers up with a torch, then do what i described above.
Drilling, re-taping/re-threading is a chore.
