Late model 4.0 manifold crack?
I've heard things about the late model 4.0 cracking the exhaust
manifold. Is this on XJ's, TJ's ZJ's, WJ's, or all? What years, specifically? Do most people just install a header when the manifold breaks? TY, Carl |
Re: Late model 4.0 manifold crack?
It is a 4.0 engine defect. It should be a recall matter because it is
exhaust and emissions related. You can tell if you have the upgraded part in there by looking for a baffle in the manifold where the last two pipes come together. Our 88's was fine until I paid some so called Jeep shop to put the front crossover pipe in for me. The jerks snapped mine and just said 'well they all break there' Ya right, my 88's lasted until they got to it a couple years ago...
