Hello Lads
I'm just signed up here tonight..found the site after Googling Honda iCTDi EGR.
Anyway, Wife has 05 2.2 diesel Sport, 140k almost.
It brokedown today so I towed it home to investigate. I'm a diesel plant fitter by trade so I'm familiar with engines and stuff but I haven't really needed to strip the Accord until today.
First thing I did was remove the pressure sensor in front of the butterfly throttle valve.., It was completely covered in gunk so I decided to remove the butterfly.
That was badly covered too, and after looking into the manky inlet manifold, that had to come off aswell.
Looking at the pictures posted so far on this thread, you're mani's are going to require removal for cleaning in my opinion.
Mine was almost closed off on the smaller ports (4 small, 4 large) because of the tar-like black gunk.
It's not that big of a job to get the entire maifold off, but it's definately nescessary to do because it will be full of that black tarry ***** right up to the inlet ports on the cylinder head.
I cleaned the manifold out using solvent cleaner in a parts washer at my garage and used a long welding rod to scrape off the stuff all the way down through the manifold.
Looking at the inlet ports on the head itself, once the inlet manifold was off, again the four smaller inlets were full of black *****.
This I scraped out as much as possible, and when I re-***emble the inlet and have the engine running I'll use cleaner sprayed into the intake to (hopefully) remove the rest of it.
I'll post up again when it's all back together and let you know how it runs.
