Robby1870 Posted June 6, 2003 Report Share Posted June 6, 2003 Well, as you can see in my sig, Im doing the rockers this weekend. Along with them Im doing new O2 sensor, O-ring, and adjustable vacuum modulator, along with some much needed cleaning. Just wanted to let everyone know, and if anyone can thing of anything else that would be good to change while its apart, lemme know (Im doing all new gaskets too and by-passing the TB coolant line). I'll post pics and get them up ASAP. In a couple of weeks, I hope to do a write up on my website about the project so others can see whats involved Robby Quote Link to comment Share on other sites More sharing options...

Guest Anonymous Posted June 6, 2003 Report Share Posted June 6, 2003 I just want to know how much difference the rockers make. BTW, what did they cost you and where did you get them? Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted June 6, 2003 Author Report Share Posted June 6, 2003 I just want to know how much difference the rockers make. BTW, what did they cost you and where did you get them? Yeah, I'll let everyone know what they do for me. I got them from Comp Cams. Here's what I got from them: 12 1.6 roller tip rockers 12 High performance hardened pushrods 12 fulcrum balls 12 10mm rocker nuts All of that with some cam lube was $176 shipped to my door. Now after all that I spent $110 on upper and lower intake gaskets, rocker studs from a Gen I 2.8, valve cover gaskets, O2, and 18mm deep well socket for the rocker studs.

Guest Anonymous Posted June 6, 2003 Report Share Posted June 6, 2003 Why did you get the 2.8 rocker studs? Quote Link to comment Share on other sites More sharing options...
NOHC_WBody Posted June 6, 2003 Report Share Posted June 6, 2003 IIRC, the Gen1 Valve covers are taller and are necessary to clear the new 1.6 rockers. Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted June 7, 2003 Author Report Share Posted June 7, 2003 Well, I dont think the 2.8 valve covers are necessary, but the studs are. B/c, this is what I think, that the 2.8 studs are 10mm (I know they are, cuz I measured them), the rockers are made for 10mm studs, but I think my studs are either 8mm or not tall enough for the 1.6 rockers BTW, whatever idiot that put my car together that decided to put every coolant hose clamp on so that you cant reach to tabs to undo it should be shot. Also, whatever moron that made it so you have to take the P/s pump off to get to the last lower intake bolt, should be shot, and whoever wrote a Haynes manual should be shot Robby Quote Link to comment Share on other sites More sharing options...
Brian P Posted June 7, 2003 Report Share Posted June 7, 2003 The reason why you need 2.8 Gen 1 rocker studs is because they're adjustable!! I hope you are getting the nuts with it too, because they're different (locking) and I also hope you've studied how to adjust pretension. If you don't know, you will be harming more than good!!! BTW the 1.6 ratio does make a difference, a nice one Quote Link to comment Share on other sites More sharing options...

BTW the 1.6 ratio does make a difference, a nice one Already got the locking nuts, came with the comp cams stuff I got. What do you mean by pretension? Cuz, my dad doesnt know what you mean by it either, I guess whatever it is, hes never heard it called that. Robby Quote Link to comment Share on other sites More sharing options...

I think I meant pre-load Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted June 7, 2003 Author Report Share Posted June 7, 2003 I'll go along with Pre-load. Yeah, I Know what that is with the lifters. Shoulnt it just be if you torque the rocker arm nut to spec, that should take care of the pre-loading, I mean after the rocker and pushrods are in place? At least thats how I thought you take care of preloading Robby Quote Link to comment Share on other sites More sharing options...
Brian P Posted June 7, 2003 Report Share Posted June 7, 2003 well yes and no, stock instructions for a gen 2 are much different than a gen 1. Gen 1 requires you to do things the old fashioned way. Like torque to a certain specification, then turn another 1.5 turns, for example. ANother way is to do it while the engine is running but that gets messy! I'm sure the rockers *should* have instructions for this. Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted June 7, 2003 Author Report Share Posted June 7, 2003 yeah, I'll read the instructions tomorrow, dont wanna get up now. But, do you know or know where to find the torque spec for the new rocker studs?? My crappy Haynes doesnt give one. And should I use loctite for the new studs?? Just curious Robby Quote Link to comment Share on other sites More sharing options...
Brian P Posted June 7, 2003 Report Share Posted June 7, 2003 yes red loctite is a good idea Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted June 9, 2003 Author Report Share Posted June 9, 2003 Update: Well, given the fact that the last three days I have had to work like 9 hours each day, my project is a little behind schedule, but all is well. After taking all the manifolds and what not off, I found that where the EGR puts the gas back into the plenum, that hole was like 35-50% blocked, and inside the plenum it was all gommed up. So, thats all clean now, along with the lower intake. Also, stayed up late one night with some 400 Grit sandpaper, and got the top of the plenum pretty shiny, and both valve covers look shiny and clean too. So, I have the new rockers and pushrods in, however not torqued down, just on. The sun decided to shorten my day today after work. So, tomorrow is another cleaning day, and re-wrapping all my wiring, prolly wont get around to gettin the rockers toqued down tomorrow, maybe Tuesday. Got new O2 in, and adjustable modulator. So, its going well, should be done like Tues or Wed, then I'll let you guys know the results. If nothing else, gettin the intakes clean and new O2 will help out.
