OMIX 17624.07 Exhaust Manifold for 81-90 Jeep Vehicles with 4.2L Engine

Junk. I thought OMIX would have some good quality control but not this exhaust manifold. Threads in bung for EGR Tube were trash (rounded the threads on a new EGR tube). I also had to grind the hold down flanges to match the thickness of the intake flanges so the bolt and washer would thread in. Exhaust ports have a lot of casting slag on them and do not match up to gaskets well. I will try and get a refund and try another brand. Eventually, 4.0L head swap will be final solution and quality parts are available for the 4.0 head.
