1.6 Rocker Arm Issues

[LeftVentricle]

Dont forget, if you want 1.6 rockers but dont wanna pay much or revamp the rocker system on gen 1's and gen 2's, '93-'95 3100's used 1.6 rockers. Readily available used and affordable.You will notice extra power.

Apologies for resurrecting this ancient thread, but I wanted to get comfirmation on this. These rockers can be installed without modification?

It's only 2 years old.. not that bad.

The 93-95 3100 rockers are still stamped steel ball-and-pivot rockers, just like in the Gen 2 engines, except with a higher ratio. They should install just fine. You might re-read through the thread, but I was thinking there might be something you have to do (washer below the nut maybe?) do to the Gen 2 studs. I could be thinking of something different, though...

I have a set of these rockers here (or 2?). Drop right in. Check the guide plates to see if the notches are deeper for the 1.6 ratio. That is all I can think of.

The guideplates from the stock Gen 2 will need to be grinded out a bit...or you could just pick up the 94-95 guideplates to bolt in without having to do any grinding. There's a picture of the stock guideplates ground out for clearance on page 3 of this thread. I initially installed a set of 1.6's w/ the stock guideplates in my 1993 Grand Prix and then saw that the pushrods were rubbing slightly(some would bottom out and some would touch the sides of the guideplates).
