I have heard from some people to stay away from buying the OEM manifolds if you going to do that job because there is a good chance they will warp again in a few years.. Is this true? Would you guys suggest a certain aftermarket manifold?

it's the otherway around.. after market manifolds like doorman and **** don't last very long.. the OEM FORD STUDS/NUTS/GASKETS and manifolds are the way to go if you plan on keeping stock... otherwise get a set of long tubes

Is that true? But its the OEM manifolds that are warping and cracking on everyones truck? After 30k im going to have another warped manifold. What about switching to headers?

My 2006 with 125k miles has never had a manifold issue. If OEM's fail every 30k then I'd know about it.

if i were you i would go with a set of shorty headers with stainless steel nut and stud kit.. use an OEM gasket set. unless you want to redo your whole exaust.. then go with long tube headers.

Yep, mine went 190k before failing. Never heard of OEM manifolds failing at 30k

I replaced my passenger side with a dorman. No issues.

How long ago and what was your mileage when you replaced it ? did you use an OEM stud and nut kit ? OEM gasket ?

Did you do this job yourself ? How difficult would you say it was ?

On a scale of 1 - 10 with 10 being most difficult I would rate it a 7 with the potential to be higher. It is not impossible for a good back yard mechanic but it ranks up there as one of the ****tier jobs I ever had to do. I planned up having the truck off the road for a week, just in case. I took my time and walked away when I started to get frustrated or needed some time to consider a better way to do something. I didn't use the entire week but I spread it out over a number of days just for that side.

FWIW I could do it much faster now but would still not like to.

Do lots of research, plan out the needed tools, especially extractors and have a welder handy just in case.

OP

I guess I have helped derail two of your threads now.

IMHO I would use OEM if you are going with manifolds. There are far too many stories of people going with Dorman and having issues shortly down the road. If you are keeping the truck any length of time, OEM. Selling in the near future, Dorman.
