Question about Nissan Navara
Hi, Ive got a Navara DX 2009 2.5. About two months ago, I thought the gasket was stuffed at the Engine Exhaust Manifold so I removed the heat shield and discovered the manifold was cracked across the middle with two cylinders either side. A friend welded it while it was still in place across the top, but the crack is probably better described as broken in half and the underside was never welded. I intended the weld to be a stop gap while I came up with the money for a replacement manifold. The weld didn't last long at all but Ive had to continue driving to work etc. Tonight on my way home from work, with the money to repair it less than a week away, the engine started to splutter or loss power for fraction of a second. The splutter became more frequent towards the end of the trip. Is this related to the broken manifold? If so, am I or have I caused further, serious damage? or will this spluttering issue disappear once the manifold and gasket have been replaced? Would it be wise to drive it to work in the morning (100km round trip)? Thanks Jay

You can clean the area really good with degreaser and apply JB Weld but that is only a temporary fix it will leak again

havent seen one yet that works, they last a day or two then exhaust leak is back, how about cutting off the flange and welding in a small piece that has a flange on it, or try to have the pipe welde at a muffler shop.

Testimonial: "thank you for your help, however the crack is just ABOVE the flange that goes above the piece your picture shows. "
I would change it, it is very difficult to weld a manifold, i know from experience. i made more of a mess than it was worth. i would take care of it soon if the fumes are coming in, carbon dioxide is very dangerous.
I hope this helps. please help me by leaving feedbck, thank you.
