I replace the cast iron exhaust manifold 4 yrs back with converter integrated on it, common problem them is cracking, has had crack since Jan but not bad an warms up good it goes away, but when start on cold start. More do, , every start a lil, it runs rough for 10 seconds or a lil more until exhaust manifold metsl where crack expand an start seal leak, the shop Say a month ago that shouldn't hurt nothing ? Not bad on valves ? Or do somethknv to variable speed timing ? Thinking of blow up to whole $1000 bucks get fix. Not wsnt to go back an put off, a anyone know when start cold start an run rough 10-15 seconds until leak seal self. If possibly bad ?

Never heard of a cracked manifold on an old clunker hurting anything. Somebody trying to separate you from your money.
Forget that fear of gravity-get a little savagery in your life.

The first time replace , much worse, I took shop, drove home. Drove old truck work, drove shop windows down, loud. ! Carbon monoxide go though vents st u , it was much worse crack, more concern if damage something on motor on cold start when run rough for 10 seconds until metsl expand an seal leak.

Don't pay attention to Walleyed. He likes to rattle people. I think your truck is running ok. Just remember to check fluids and change the oil. I don't think you need to worry about the truck.

A crack in the manifold will allow air into the exhaust, This fresh air in the exhaust can skew the readings of the oxygen sensors. Not a big deal for the sensor after the cat, but if it is the sensor in the manifold next to the head, this can affect the fuel:air ratio being supplied to the engine. That may be why it runs a bit rough when it is cold. I've "heard" of guys replacing their O2 sensor with a dumby one that effectively bypasses that reading.

Is everyone nearly as sarcastic as u in that part country ? Or is that u normally like ? Trying to give you some sound advice, coonman. A bicycle would give you many years of useful transportation and fewer parts to diagnose when you have a mechanical issue. Scrap the Colorado and use the proceeds to buy a used, serviceable bike. You'd save in repair bills, get good exercise, and help save the planet !!! It's a WIN=WIN situation for everyone !!! You'd get dependable transportation, and we'd be spared a weekly diatribe on your vechile woes !!! Carry on, coonman. w

Coonman --go to AutoZone and buy the compound that seals small holes and cracks in manifolds. I have used it and it works. Cheap too! Thanks for advice , but in cast iron, cracked. Replace is all do. My ancient junk 87-S10, which never drive much, save emergency vechile. Should be junked, would not trust all, or shutoff if went somewhere, N bad rust throughout an frame, not to safe. Anyway that has aluminum manifold an was successfully welded years ago

Not a big deal for the sensor after the cat, but if it is the sensor in the manifold next to the head, this can affect the fuel:air ratio being supplied to the engine. That may be why it runs a bit rough when it is cold. There is a O2 sensor go right into exhaust manifold. Can't see if in converter, because shield, just concern when run erratic on cold start for 10 or more seconds because crack in manifold. Until metal hot expand an run normal that could damage valves. Or screw up timing, if goes out time. Ur motor is toast, the shop Say shouldn't do nothing motor, but exhaust in cab is not what want. I pretty sure at times, at idle an park few min or cold start , smell exhaust. , It been that way the same since first year, just wondering if thst rough idle at first until metal expand an stop leak an run right , if rough idle could screw up motor ? I believe my old truck did same thing crack manifold except worse. , Until welded.the cost an cast iron manifold ridiculous, at gm garage, it be over $1500, was bad gm design, evaporater drip water manifold weaken,

Didnt know you rode a bicycle walleyed. Or are you one of those democrat "do as I say,not as I do" types.
