Question about Nissan Navara

Cracked Engine Exhaust Manifold

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

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. "

SOURCE: should I change or weld my cracked exhaust

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.

Had 4 exhaust gaskets replaced over two year period now I have the same problem again

Hi Don. Is a shop doing the gasket replacement or was it a D.I.Y. thing? I ask because the problem may very well be a warped/cracked exhaust manifold, or worse a cylinder head issue. If your doing this yourself, perhaps remove the exhaust manifold and take it to a shop to be checked for warpage or cracks, and simply repace it (along with a new gasket of course) if yours is found to be faulty. Also, use new hardware ( studs/bolts) to install the manifold and torque to proper torque specs. Proper torque is important.

I got a 1999 gmc sonoma 4.3 v6 vortec I have strong exhaust fumes coming threw the a/c vents while the a/ is on

You have a leak in the exhaust system. Have it looked at soon. You don't want to be breathing carbon monoxide while driving. If you hear a "ticking" sound while the engine is running (more predominant with a cold engine) it's most likely an exhaust manifold leak, either a bad gasket, broken stud or cracked manifold. Other possible causes could be the "donut" gaskets that seal the Y pipe to the exhaust manifolds, the Y pipe to catalytic converter gasket (if equipped).

Blowing anitfreeze out the tailpipe. I know this means a head gasket. When the engine runs, it blows antifreeze out the passenger side of the engine at the exhaust manifold by the middle cylinder. Does...

could be just head gasket and bad exhaust manifold gasket (coolant leaks past head gasket into exhaust port then leaks out of exhaust manifold gasket)
or it possible that head is cracked too
Only way to know for sure is to remove head and inspect it

Hi i got problem with my bmw e39 540 i auto .when engine warm it changes gear late and got a whisle noise .it only does when engine warmed and if i turn engine of and wait for 20 min or less it gets normal...

Look for vacuum leaks, late shifting can be a result of lower than normal manifold vacuum, look for dislodged or broken hoses.

My thought is when you find the whistling, you will have the solution...

1995 cherokee 2.5 td 150k miles will not start.

The oil pressure dropping to zero is common for cherokees. Replace the oil pressure sending unit and it will be good as new. Cracked exhaust manifolds are also common. Usually it will crack where the 2 pipes are welded into 1 pipe before it connects to the front pipe. There are lots of replacement headers out there to choose from. I just ordered one through quadratec.
