How to tighten rockers??

[Shah]

I think I know what im doing, but im not a mechanic so could someone give me a quick run through. I know I have to remove valve covers and tighten the rockers, but i need to know specs and tools needed. Thanks

this is for your v6, yes? why do you think they need to be adjusted?

Im hearing some ticking noises. Im not sure it that is the problem, but I want to try and fix it before I take it to a mechanic.

as i understand it, the 3.8l just uses a torque spec for the adjustment. i havent been able to track it down as yet.

are you confident that tick you hear is either lifter or rocker arm? do you have access to a mechanics stethoscope?

is the tick only at cold startup? only after hot? does it seem directly related to engine rpm?

To answer your questions:

1. Im am not 100%, but from talking to some of the guys it seems to be the rocker/lifter.

2.No stethoscope

3. Only at cold start up, then lessenes when engine gets warm. I havent let it heat up all the way.

4. Ticking increases with increase in rpms

on the 3.8 you tighten them down to 15lbs then go an additional 90 degrees

I have seen 11lb and then 90degrees for the 3.8

I will have to look in my books

[thursday12889]

yeah so you'll need a torque wrench

[97rs4life]

yup 11lbs and then 90*

page 24 of 27 has the torque specs. You will need a torque wrench. Also be careful as the stockers I believe are TTY (torque to yield). You will also probably need a valve cover gasket just to make sure it doesn't leak when you put it back on

it says 15 right on alldata

[1BADAIR]

if they are TTY they need to be replaced if loosened or retorqued

[97rs4life]

it says 15 right on alldata

yea but that is Nm, 11lbs is 15 Nm

[Keego Ridah]

yea but that is Nm, 11lbs is 15 Nm

good point buddy
