i know everybody and their mother posts about this, but i am having problems snapping the bolts connecting the flanges of the manifolds to the stock y pipe, how to i get the bolts to a) stop snapping and b) how do i get the y pipe off of the manifolds now so i cna get to the manifold bolts?

what size wrench are the o2 sensors?

Also how do i get the egr and air off because the headers i have dont have hook ups for them

 

Why worry about snapping the bolts holding the Y-pipe to the stock manifolds? You're going to throw the manifolds in the trash when you install the headers.

 

If the heads of the bolts snap off it's no big deal as the ypipe will come off anyways.

If you want to make it a little easier on yourself anyways, just soak them in PB blaster overnight.

I just use an impact gun with an extension on them where it fits.

 

Like the other guy said i'd put some Pb blaster on them. I used it on mine but i think all them snapped off but one. However i would defiently use pb blaster on the other header bolts because you dont want one of those breaking off.

 

PB Blaster is da' shizzzz.

 

Yes, use PB Blaster on everything. Each of the 3 bolts conecting the Y pipe to each manifold, all 6 bolts connecting each manifold to the head, and on the AIR and EGR fittings on the manifolds.

I can't remember exactly what size the o2 sensors are, mayb 3/4"... Just use PB Blaster and your life will be much easier.

 

i dont think i would have survived my header install without PB blaster. that stuff is like a gift from god

 

Yep, yet another advocate right here for PB Blaster. I soaked all of the old hardware for a few days before putting a wrench on anything and everything came apart easily and nicely.

 

PB blaster was a gift from god he gave it to Jesus the first time he had to remove the water pump on his LT1 Camaro

 

If Jesus really had a pipe to God, then he should have asked for a direct opti replacement, too.

 

God has appoligzed for the Optispark and also Mustangs and Honda Civics
