ok, on my stock manifold the heat riser flap do-hicker the springer is broken. what is the best way to fix this. if i took it all out would it hurt the flow. seems like it wouldnt flow well anyway. what is the best way to fix it because i cant see a way to even take it apart?

someone chime in and be nice

thanks guys, dustin

Get a hammer.


A hammer can fix anything.

come on man...i need help here even tho i did "hammer" the new guy

Is any part of the spring still there?

If so, you may be able to bend part of it so that it works again. Clockwise is cold direction, so have it setup so that the reworked spring just manages to rotate the lever clockwise (when cold).


If the spring is hopeless, I'd just rotate the flap full counterclockwise and wire (or whatever) it in place.

will it hurt cold weather driving a significant bit

Actually, the spring tends to keep the flap open to heat up the intake manifold. With no spring, the flap will tend to go into warmed up mode and be fine.

So you really don't have to do anything. Warming up the carb will just take a little longer, and if you're not where it's really cold, it probably will be ok

ok i appreciate the help got it under control

next question is that after i get that fixed...im thinkin about wrapping the manifold with header wrap to reduce heat on the intake manifold and engine bay itself


then im thinkin about getting the heat reflective stuff and wrapping the intake


good or bad idea

any input

The cast iron manifolds are known to crack.

Not sure that keeping the heat in them is the best thing to do........

what about wrapping the intake?

no idea


my first reaction is why bother, doesn't get all that hot.

just out for doing something different and pointless i guess

thought someone here would have tried it

What year car do you have? As long as you have an air cleaner with heated intake (a "stove" around the manifold where the exhaust pipe bolts on with a hose running from it to the air cleaner) warm up shouldn't be a problem. I removed my flaper valve (much to some peoples dismay) and have no problems with cold weather driveability. However....alot of time was spent adjusting the choke to accomidate the lack of the heat to the carburetor base.

You definitely DON'T want to hold heat in the intake manifold. You'll get best performance and economy if the incoming air charge is cool, a hot manifold will work against you,
