Cause and effect of a cracked manifold?

[getto]

My 89 fj62 has a cracked manifold- or so the Toyo dealer says- and I was wondering how easy of a fix this is? Is it expensive? Time consuming? How does it affect the truck's performance? Thanks.

I'd say that it's a 7/10.

Mildly expensive.

About 5-10 hrs labor.

Vast improvments in performance if that is truly the problem.

Which manifold is cracked, where and how badly? This all affects the answer.

That's a good question. The dealer just told me the manifold was cracked. I need to dig deeper into this because I am getting very poor gas mileage and my LC is running very sluggish. How would I tell which manifold is cracked? Thanks.

You should ask the dealership to tell you where the crack is and show it to you.

it is probably directly below the carb.

I am assuming that it does not have a header correct?

FJ-62 right, so no carb. Does your idle bounce up and down? That is one symptom of a vacuum leak. You can spray some carb cleaner around the manifolds to see if you can pin point where the leak/crack is.

Missedt he 62 part.. (in the us at least )

Seriously different intake..

They didn't tell you if it was the intake or exhaust manifold?
