I think I will do it myself and see how I make out, if nothing. Then I will and I want to be there when they do it

I sent them an email a little while ago about it. No response yet. I think they need a manifold with the air pump holes. Does the other ones clear the air pump. Can you keep it on it or do the headers not clear it? Thanks a bunch.

NOPE

Well I worked on it tonight for 5 hours and came up with nothing. It continues to leak I think its eaither the manifold or the Y-pipe. Is it possible there is to much back pressure? The car runs fine and does not over heat. There are currently no headers for my car but i know they are working on them I drive it for now with the leak, in the mean time, what do you recommand i do? What could I do instead of headers that would cure the problem? I was thinking bring it to a shop and having them take care of it? Any ideas? Thanks guys

Get a new set of studs for the manifolds - if what i'm reading is correct, somewhere along the line, a shop screwed up one of your studs?

That would explain the lack of seating correctly.

On my '88 Camaro - REMOVE THE BATTERY CABLES - BOTH.

You do NOT want to touch the starter cable on the passanger side if it is still hooked up to the battery!!

Anywho, if you disconnect your starter, and drop it down (2 bolts) then you should be able to get to the bottom stud easily. If you have small enough hands, you can skip removing the starter, and just reach up there - the flat side of the GM Iron donut will face the manifold - the curved part goes 'in' the Y pipe itself.

Tighten the bottom nut by hand, while a friend is holding the donut from the top - just to make sure it stays even. You should not have the donut with a 'lip' on the sides of the manifold.

Tight the top nut by hand, as well, then EVENLY TORQUE THEM DOWN.

The Driver's side, same theory, but easier to get to.

Personally, given the temps and all - I'd ride with the leak, and save up for the Pacesetter headers.

I understand not wanting/having the money to do them now, but you will be LIGHTYEARS ahead by doing that later, rather than throwing money at it right now, IMHO

O yeah. I did the same as you told me. I tighten them evenly and the darn things still leak. I replaced the studs tonight and nothing. Mainly leaks on the passenger side I think something must just be screwed up I spent 5 hours like i said and froze I must say. Way to cold out Hopefully I will be able to get some headers made up for it? But is there any other solutions or anything that could be fab up or have a shop do? I have honestly given up until I get some headers

Take the car to another muffler shop.
From all you have spoken about, everything is there for proper working operation.
Leaking upon start up is indication of not seating properly.
Cracks in manifold? Certainly.
Especially if someone used the pipe system as alift point.
And that does crack exhaust manifolds.
This happened to my car.
The "Y" Pipe showed no damage. Yet the manifold, passenger side, was cracked.
Find another muffler shop for help.

Yeah, I have to start looking and seeing which shops are better then other ones and go from there. I know the manifold can't be cracked because with the soft seals it doesn't leak, just these. I don't know what I will do. Can't wait for headers when they come out . Lets hope soon. I'm not going to touch it until late spring when its warm unless it gets worse which it better not. Any other good suggestions
