As far as I remember you can't do it all from underneath unless you are an experienced proctologist. The air cleaner assembly is above the manifold and removing that means removing all the duct work on the firewall etc. The guys at Autologic did mine as well as the PCV valve and the glow plugs at the 200K service.
I would be very interested to see your comaprison between the manifolds. Check to see if the ports match the gasket. The one I saw on the net had the EGR port coming off cylinder one only. Having less exhaust gas in the intake tract is not ideal for emissions, but I am not sure what effect there is on partial throttle tune. Closed or Full throttle will be unaffected. Cheers |

Can't notice any difference in driving with the egr bypassed, except less hesitation when taking off. I'm not 100% sure it is the manifold , but everyone says they crack, a mech told me he'd never seen one that didn't have at least a few cracks... It could be the turbo, I noticed one morning what looked like a stream of exhaust coming out from my front right hand wheel arch whilst I was waiting to turn right, but then it disappeared later... I've changed the air cleaner element, and are going to replace the breather , just got to find an E-torx socket to get it off, never seen one like it before. If I have to remove the intake , I'll do it, but I've read the injectors can weld themselves in and be hell to remove. I'll remove the covers, air cleaner etc, and then go underneath, after I find a cast iron manifold...

I wanted to know if it could be done without removing the injectors, that's a relief. The turbo, I'm thinking whether to replace it just to be safe, but they're not cheap. Did you have to remove turbo to get to the manifold? Did you just use WD40 to loosen up the bolts? The cast iron manifold you used, was it from a earlier BMW diesel or a new cast iron manifold made in the the same design as the stainless one more or less?

Nice work Skier1.
I looked into this 2 years ago and have always regretted not fitting the cast iron manifold. I am not sure why the injectors need to be removed? as mine were not touched. Did you notice any difference in the engine noise as mine has an exhaust resonance from the OEM manifold at 2500 especially when cold. Cheers Dan. |
