That is the intake after the egr. I always thought egr on a Diesel was a bad idea. If my 300d lacked power this would be a good thing to check, but I plugged it up years ago. - ------Original Message------ From: Edward Pomeroy To: Dj Subject: Re: [db] this could explain it... Sent: Sep 5, 2010 04:43 John Is that the down pipe off the exhaust manifold to the catalytic? It seems too wet for that. Please explain as my Jetta also seems to lack power above 3400 RPM Thanks, Edward On 9/5/2010 1:06 AM, john wrote: > no wonder the TDI wouldn't produce power over 3,000 rpm... > > http://johnmeister.com/DIESELS/tdi/JEM_8496-tdi-155k_2010-09-04.jpg > > > > > > ----- > ------------------------------------------------------------------------ > when replying, please reply to: fotomeister@comcast.net > john@wagoneers.com does not get checked often and is heavily spammed > ------------------------------------------------------------------------ > Snohomish, Washington -o|||||o- where Jeeps don't rust, they mold > http://AMSOIL.com/redirect.cgi?zo=283461 si vis pacem, para bellum > http://johnmeister.com http://wagoneers.com http://fotomeister.us > ------------------------------------------------------------------------ > > Sent via BlackBerry by AT&T ------------------------------ Date: Sun, 5 Sep 2010 15:13:09 +0000 From: dieseljohn@comcast.net Subject: Re: [db] this could explain it... No, not burning any oil at all. Tight engine, no oil use. This is apparently normal on the super clean tdi's. The newer ones rightfully claim to be cleaner than the peeus, and of course even an older tdi will get better mileage on the highway. The egr valve was also clogged, have a picture when I separated it, didn't spend a lot of time on the pc last night. Will provide more after it's all together again. This is why an egr valve on a Diesel is such a bad idea. The tdi even has a cooler on the egr so the recycled exhaust isn't hot. But the unburned carbon particles collect around the valve inlet and the intake manifold and accumulate. This engine has 155,000 miles on it. The intake has never been cleaned. Not sure how often this 3 hour job needs to be done, but there is a calibration process to reduce the egr output which should reduce this. Need to read up on it. This engine passed emissions with flying colors, 1% opacity out of 20 max. But didn't produce any power over 3,000 rpm. It would rev to redline but it wasn't pulling any more. Used the propane and air trick to clean it out. Started the carbon on fire with the propane torch with a wet rag over the manifold in the driveway, added air and had flames coming out of the ports for 10 to 15 minutes. It's soaking in my solvent tank now, will install after church. Will post more pictures and maybe some really poor video of it, with links to some videos found on youtube. Will be in the same path, new directory called egr-cleaning ck back in a few days. :) John - ------Original Message------ From: FParker Sender: owner-diesel-benz@digest.net To: dbl Subject: RE: [db] this could explain it...

The propane trick might work. The shops send them out, they use ulrasound to clean them.
