howdy


i have a 1994 Z28


i have a bolt thats broke even with the block (i believe) that is closest to the firewall. and now there is an exhaust leak right around where it is (i can reach my hand back and feel the air coming out when the car is on.


few questions about this now.

1) would there be any way to jack leg a fix? even if it is only temporary

2) would fixing this be something average joe could do?


any suggestions or input would be greatly apprecated

 

About the only thing you can do is pull the head and get it fixed there isn't enough room to do anything in the car.

 

Take the car to a exhaust shop and have them tack weld a nut to the broken bolt.It is possible i have seen it done and done it my self.Dont worry you will not mess up the aluminum head as long as its done carefully.It should'nt take much torque to get it out.

 

^^ yeah he is right. its a 50/50 chance though... better worth a shot than not right?

 

You will probably need to loosen the exhaust manifold and drop it down to do this.

 

would this work if the bolt is broke flush?


i'm doing some research to see if i want to try to tackle this myself...and pray to god i can get a pair of vice grips on the thing to get it out

 

The bolt being broken flush is exactly the problem i am talking about.What i recommended has worked every time for me.

 

appreciate the tip sincal


that never occured to me

live and learn eh?

 

How many times have you broken bolts off in the head?


j/k

 

I tighten all my bolts to GERMAN specs!!! (GooooodnnTiight)

 

If you're planning to upgrade to headers anytime soon, then you wouldn't have to remove it. Theres 2 bolt holes on the end, manifolds use the outside and headers use the inside.

 

hmmm i didnt know that


ill definatly have to look into a set, and read up on em, see if i can do it myself



any suggestions on brands?


will i have to mess with any of the exhaust pipe from there to the back?

 

Most headers you will have to modify at least to the cat, maybe to the axle.

 

You could go with Mac shorty headers, the use the other holes and come with all the AIR fittings and a Y-pipe. Think you might need to have a flange welded for the cat? but you have a good excuse to add headers. Allot easier then pulling the head too!

 

i took it to my buddies shop, and he said the cat was starting to leak....so hmmm maybe ill have an excuse for headers after all
