Cracked Header

I was wondering if $300 to fix a cracked header was a decent
price...or if there is a cheaper way to fix it..

if ya have a wire feed welder you can just weld it up. Not sure if an arc will work...it might. I'm pretty sure an oxy-acetanlyne would get the job done. Check the classifieds ont his site...I'm sure you can end up with a used header for about that price if not less.

orignal header or aftermarket ?

either way that sounds kinda expensive......

you can usually pick up a set of stock used headers for under $100

check ebay they usually have a couple available or you can check out Ian at 944online.com



good luck

it is an original header.... the mechanic i went to said it was too close to the engine to weld...would a wire feed welder make a difference?

for that price you could probably get an aftermarket header (bursch?). Also, I am not sure, but since you have an early 85 you probably have the heavy cast headers, you could always upgrade to the later lighter ones.

wow, I've never heard of the early cast manifold cracking, which one do you have? I have a good used set of cast ones if you're interested. I always thought they were bullet proof, usually the later tube ones crack.

If you are going to repair the stock cast manifold by welding, make sure you preheat the manifold before you weld it. Also, how much lighter are the later exhaust manifolds???

Both styles seem to crack somewhat often. Most problematic ones are the 82-85 iron headers, these tend to crack @ the 2 into 1 section of the piping, on the upperside. There's enough room to weld them, if your mechanic isn't comfortable w/doing it, tell him to take it off. I don't think preheating is necessary but that's my opinon. 86 model turbos also crack, later ones included an expansion joint on the #1 cylinder to combat this.

The later manifolds are quite a bit lighter than the early ones. I don't think it'd be worth it to spend money on headers on any 944 except to upgrade to different fittings on a 944 turbo, if you're upgrading to a garret turbo. As I often say, US 944s share the same manifolds as the european cars, that had higher compression, and no cat. One can only conclude that they flow well enough. Any "gains" would then have to be just shifting the power band (as in tuning, and not actually making more power, ifyou were to look at a torque curve, the area under the curve on a 944 with aftermarket headers vs. a 944 w/stock headers whould be about the same).

Also, in the future, please use the search feature, this question was asked, and answered on the current page, as I type this.

In all my years, I've never heard or seen a cast one cracked, on the other hand I've seen about 4 of the later style n/a's do this, as for the turbo's, well that's a different story.

If you weld it with a MIG or some other electrical welder, you'd better remove the chips. Or remove the header.
