Been reading the forums for a while. Sometimes my wife asks what i'm laughing at so hard and i tell her that it's all this learning that i'm doing just tickles me down deep. So thanks guys for all the great info and the very entertaining way that most of you deliver the messages!

Among other things, we have a 1959 Chevy Apache with a 235 cu in engine. It has developed a leak in the manifold gasket (s). Before i go digging into that, i was wondering if anyone knew where i could get a NOS intake and exhaust manifold. any suggestions other than Ebay would be very helpful.

thanks again for the great knowledge and wonderful delivery. This sight is a blessing to us because of all of you who contribute.

Blessings,

Oldtruckspapa

If you separate the manifolds, tighten them to the head individually before tightening them together. Good place to use brass nuts.

I have a 3835587 exhaust manifold for 20.00. The best gaskets to use are Remflex. Have them on both my 1954 235 engines..Bill

Leaking exhaust gaskets are not all that uncommon on these motors. So before you pull the trigger on NOS, and start taking apart the assembly ,check the condition of what you have. If the manifold is not cracked, and the flapper is not frozen, remove the assembly and as suggested above, use a Rimflex gasket. A littler more in the way of cost then a stock type gasket but its a one piece gasket and seals like you cant believe. Way way better then stock.

Oldtruckspapa ,

Why do you think you need a new intake & exhaust manifold ?

Finding a GM NOS intake & exhaust manifold will be next to impossible to find .

I purchased a nos intake manifold back in 2008 .

I've only seen one other nos intake manifold that showed up on ebay in 2009 .

After keeping my eye out for a NOS exhaust manifold since 2007 .

One turned up on ebay last year . It's a super rare part in nos condition .

Both GM NOS manifold's had to carefully media blasted to clean off

light oxidation & light surface rust .

This is what I used in my blast cabinet .

Sorry it's taken so long to get back to yall. Let me first thank those of you who responded. George, thanks for the info on Corn cob media! and Dragsix, thanks for the Remflex suggestion. Bill i'm still trying to figure out how to get you my email address.

so, removed the manifolds and found neither was cracked or damaged so don't think i need the NOS that is impossible to find anyhow. However, the heat direction plate is frozen partially open. anyone know how to get it unfrozen? doesn't look like someone did it on purpose as was suggested in another post on this sight.

If i read and understood correctly, some have indicated that that condition would be ok and should operate satisfactorily. however, i'm going to exhaust all possibilities to try and find a manifold that has an operating heat flapper.

thanks again for all the great input!!

Blessings,

Oldtruckspapa

Thanks for the update and shout out but I would like to note that 49 3100 noted the rimflex gasket first. So you had two positive recommendations on the gasket!
