Hey fella's I have a 1999 s-10.I've had it for about 4 years.When I got it she had a 106,000 and now 197,000.I almost gave up on her Honestly.


Pretty neat little truck.It's a 4.3 with a nv3500.It's 4wd with a regular cab shortbed.I had the rearend rebuilt with a posi unit and it has 3:42 gears.I put a centerforce daul friction clutch in it.It also has a hurst shifter and a tach in it.Was my daily driver for 3 1/2 years.I just had the intake off and replaced everything with a/c delco parts.Fresh tuneup using ac parts.And there is no service engine light on.

Last december the slave cylinder went out.So I took it off the road and replaced the slave cylinder and throwout bearing.I think I made a mistake and bought the parts at autozone.I normally always use ac delco parts on it.

Well today I got the insurance put back on it and took her for a test drive.

The motor seems to be shakey and gets worse as you rev it up.The new throwout bearing is alot louder.Everything went back togother smoothly.The motor never goes over 180.Has a steady 45-50psi oil pressure.Power seems to be fine.Has plenty of it.I broke the tires loose at 50mph.HEHE.That is why I love this little truck!

I don't understand what I could of done that would cause this to happen.Everything seemed to go togother smoothly.The trans shift's awesome and seems to have the crank centerline and input shaft aligned well.Slid right togother.



The next thing I was thinking is the harmonic balancer.Also underneath the intake the motor had a shaft.It was in the lifter valley.I believe it has something to do with engine balance.Is this correct?Can this part get wornout?


Does anyone have any kind of idea's?


Thanks.
