Does anyone know what would it cost to have the intake manifold cleaned out by the Nissan dealer or a competent workshop? I am researching for a used GU5 or later (CRD motor) and am wondering if high mileage examples will require an intake manifold clean. I don't have the skills or tools or facilities to be able to do this, so I need to factor in the cost of getting this done properly by professionals.
Thanks in advance!

Not sure of exact costs, a Nissan dealer may be quite expensive, and your local mechanic less but still probably a few hours work. My mechanic said he could do a manifold clean, and install Dawes and Needle valves and block EGR for around $250.00 which sounds pretty good.
I would say that if it has never been cleaned or had the EGR blocked from new the throttle body and manifold may be very gunked up. After a clean and EGR block I'm under the impression that it should keep clean and you won't need to do much maintenance in that regard.
Dawes valve finally arrived the other day so I'll be getting it installed tomorrow along with Needle and EGR block. I've decided to just get the mechanic to take apart the manifold and clean it directly, I guess this will be the most thorough and I'll know it's clean, and for around $250 I figure it's not too bad an outlay for peace of mind.
My mechanic couldn't get the EGR4 product and the only similar thing he had was for petrol engines. I reckon the best way to get the EGR4 would be through a Nissan dealer (as long as they do the work), or apparently it is more readily available in the Eastern states so you may have more luck if you live there or know someone who can source it and ship it over.
I'll let you know how everything goes after tomorrow.

sure all will go well and $250 is an awesome price...... i just got a price today of $585 just for inlet clean $89 included for gasket kit........ i think this is a bit steep

I called a local Repco in Melbourne who knew of it but never stock it. They contacted the Wynns Vic rep for me who wouldn't let them stock it but he gave me the rep's mobile number.
I haven't chased it up actually, got too swamped with work but having seen the responses from elsewhere, I'm not too confident I'd be able to get it.
Yeah I'm sure you'll get the same spiel I did from the rep, and they'll point you in the direction of a dealer. It'd be interesting to know how much it would cost getting it done through the dealer.Originally Posted by twisties
Yeah this was just a rough estimate so hopefully it doesn't take him much longer!
Taipan exhaust on the gold coast do the wynns clean when inlet not too blocked..... think he told me about $120 that was 3 weeks ago but now i went with an opposition exhaust i am a bit embarrassed to go back to them....

Everything done today and wow, it's like I'm driving a different car!! I'm very happy, Dawes and Needle work great and EGTs are much much lower, down to about 230-250 deg 60km/h around town.
My mechanic found a lot of carbon build up in the manifold, similar amounts to the throttle body. This would contribute to the lower EGTs I'm sure, but it took my mechanic much longer than he thought. He was kind enough to charge me what he quoted (even though I was protesting trying to pay more or what it really cost) so all up $250 for the manifold clean and another $30 bucks to install the Dawes, Needle and block EGR. I think though he would probably would have spent at least a couple of hours more on it, so probably still a fair price would be around $400 or so. He said he was putting it down as a learning experience - what a legend!! He also took the time to come for a drive with me to check the boost levels etc and make sure it was all working ok.
I'm definitely glad I got the manifold done just for peace of mind but obviously it's had an affect on the engine. I would imagine stock engines having done around 200k would have similar build up of carbon so would be worth doing.

Yeah I thought 2hrs was optimistic. I'm fairly handy on the tools and it took me all day. Mine looked like the picture in the reference documents after 150k and I defiantly noticed a difference when I did it.
