66 - exhaust question

[Stephen L.]

bb car - took exh manifolds off to clean them up

put the rh side (passenger), fine and exhaust pipe went right back up into side pipe cover

but lh side has not...it is sticking farther out and will not seat properly in the side pipe cover - everything went back together the same (new donut on both sides between the exh pipe and the manifold - but that (disintegrated) was there before

stumped.....

Re: 66 - exhaust question

Steve,

Driver's side has the heat riser valve. Donut exhaust extension sleeve(on the exhaust pipe side of the valve) goes into heat riser valve. Is the donut exhaust extension sleeve fully seated into the heat riser valve.

On the new donut, partially crush it first on the passenger side and then move it to the driver's side.

Re: 66 - exhaust question

Douglas...on my car the heat riser assembly is on the passenger side (this is a BB car...might you be thinking SB?)

as for the donut, i just torqued it to the aim spec (17ft lbs)

Re: 66 - exhaust question

Steve,

It's a good thing these cars are only a hobby for me! Yup, heat riser on passenger side. But, my main point was that the exhaust extension sleeve may not be fully seated into the exhaust manifold causing the side exhaust pipe not to clear the exhaust cover, especially with a new donut. Good to hear you got her all back together.

Re: 66 - exhaust question

thanks Douglas

back together yes..but with the exhaust pipe jammed up and only partially under the shield!

Re: 66 - exhaust question

Steve,

Try disconnecting the side pipe in the rear and connecting the front to the exhaust manifold first. Make sure you are using the exhaust extension because it helps the side pipe correctly aligned coming from the manifold. If that doesn't work, try putting a very small amount of lift under the motor as it might be slightly shifted in the motor mounts.

Re: 66 - exhaust question

Douglas - thanks folks have mentioned a steel collar and now you mention an exhaust extension...is this the same thing? and if so, what is it!?

when i disconnected there was nothing that acted like a collar around the donut - there is the tail pipe, the triangular piece that fits over the studs - the donut between them and the exh mani - and on the other side the heat riser

where would this extension/collar go? - do you have a part number or a page in the aim?

thanks!

look up Exhaust Donut Alignment Sleeve part nos. 4093, 4094, 4095 in Paragon.
The sleeve transitions the manifold to the head pipe, with the donut around it.

Re: 66 - exhaust question

Stephen,
If your exhaust donuts have never been changed, it's a good chance that the original steel alignment sleeve just rusted away and that's why you didn't have one in there when you initially took it apart. As has been mentioned, this sleeve aligns the header pipe with the exhaust header. Install this sleeve and loosely snug the three bolts at the exhaust manifold. Then attach the rear of the pipe in front of the rear wheel. You should then be able to align everything to make it fit inside the cover. Good luck and let us all know how it turns out.
P.S. Paragon sells both stainless steel and regular steel sleeves...stainless will outlast most of us.

Re: 66 - exhaust question

got it!! makes sense now

yes, i suspect the original ones are rust flakes blown out through the exhaust over the years...absolutely no sign of those when i took them apart

thanks guys

Thanks Leif - yes, that is what i am going to do...loosen everything back up and start over...it came apart so it has to go back together

thanks
