I'm a newb to this forum but not to most anything automotive. Especially repairing or modifying, I'm more into muscle cars but work on most anything. I've searched the forums for the answer but didn't find one. The question being. I've rebuilt the quad 4 in my 95 cavalier Z24 and am second guessing the balance shaft timing procedure. I can re-time the shafts allot easier now on the stand before I install the engine, if need be. The FSM states the procedure as, Place number 1 piston at TDC, then rotate 90 degrees, install balance shaft locking tool and install the sprocket an chain to the shaft. Now my second guessing part, which way do I turn the crank an additional 90 degrees? I turned clockwise from the balancer pulley and now realise that this engine runs counterclockwise. So now do I have the balance shafts 180 degrees out or not? Any quad 4 gurus out there know what I'm talking about. I do know that the balance shaft system was added to this motor in 95 and the carried over to the Twin Cam in 96. I sure would appreciate any help or direction as to where I can find the answer Thanks in advance Mark
The engine runs counterclockwise? Since when?

Must only run that way in his little world. In the real world they run clockwise.
I used to race cars, now I race myself.

Perfect solution to your problem, get a real quad4.
When my balance shaft assembly went out, that was my wisest choice so far with my car. Now I have more power, no balance shafts and a love for my car that will never end.
Ok!!! So, That was my first thought but when I had motor on what I thought was TDC and turned motor counterclockwise the ehaust valves opened leading me to think that the enginge ran in that direction. But, I quess I had the motor at the top of the exhaust stroke!! And turning backwards opened the ehaust valves again. Sorry for the mistake, but I still need to know if I timed the balance shafts correctly. What do you guys think?
When I rebuilt a 96 grand am 2.4 9with balanced shafts), we did not have to time the balance shafts. Only the timing of the motor it's self.

Hi John
did the balace shafts run off the crank with a chain and sprocket?
if you get them unbalanced i was told youll gain 18hp, thats what i plan on doing, can anyone confirm this?

You might be confusing "unbalanced" with "removing." Removing the balance shafts will gain you more power, but even with that, 18 is a bit high.

"Youth in Asia"...I don't see anything wrong with that.
is the 2.3 oil pump an external pump, cuz im not getting exactly how this removal works.... Does the whole bal. shaft housing get removed or just the internal pump and balance shafts....because that damn housing weighs close to 50 pounds....im going to have a machine shop do this for me but i would like to have an idea in my mind of what all is done.....

No, the 2.3L pump is internal. Everything is removed, even the housing. The 2.4 gear on the crank also has to be removed and the 2.3L one heated and tapped on. There are also new oil passages that get drilled, as well as others drilled and tapped. If you would like pictures of the install, I have the ones that someone gave me a while back. I did mine slightly different though...The NY-Jbody way.

The engine turns clockwise, as do most others.
The balance shafts are geared to turn at twice the crankshaft speed, so it doesn't matter which direction you turn it to 90°. The point is to set the shafts with all the pistons halfway down the bore. The shafts will be in the same position at 90° BTC and 90° ATC.
