hey guys I was gonna tighten up the valvetrain on my 93 3.4 and was wondering what you all suggest I do, I have a little knocking from the rockers, the car has 148,000 miles on it so I'm sure that it needs to be readjusted. If anyone's done this before send a few pointers my way. Thanks guys....

 

hey guys please help me out before I screw this thing up, I'm gonna do something either way at about 1:00 today so give me some pointers, please! Thanks

 

maybe you should leave well enough alone and let it live out the rest of its days?

or maybe i'm just saying that because i have no useful advice for you.

 

Buy some rocker clips and tighten them with the engine running.
Thats the way I like to do them.

 

Its a pain in the ***...

you need to remove the upper intake plenum fuel rail and injectors...


then the valve covers but its a little bit of a bitch because the AIR pump lines snag on I think the driver side valve cover making it difficult ot get the valve cover off.

it also helps to remove the alternator.

I would buy like 3 cans of engine degreaser, and a old toothbrush and soem rags... While you have all your stuff apart... its a good idea to clean it like the top of the lower intake maniflold and the insed of the upper intake plenum and the throttle body.

i would also take the igniotn coils off and clean up all the points with some sandpaper.


As for adjsuting the rockers.. i don't remember the exact procedure... but I do know it involves, putting the motor at top dead center... tightening certain rockers... then crank it a certain amount, and tightening certain rockers...

It list the procedure in a haynes or Chiltons manual... may want ot pick one up or at least read the right order.

I reccomend jsut loosening all the rockers then doing the tightent down process...

I did this about 8,000 miles ago and haven't had a tick since... I had some serious ticking.... And either fixing that or doing a serious cleaning of the throttle body and upper intake gave me back a few horses.

If you absoultely need me to type up the procedure I can.... jsut not tonight I am at my girlfreind's place, its 3 AM I jsut got home form work and I have to be back at work at 7am. So may be a couple days before i get it up if you want it.
