I cleaned mine as well and I think we should check it every 3,000 miles and if it looks good, then do it every oil change. I took my intake apart and it was and EGR was ok not full of goop..

Sorry, I'm borrowing DnA Diesel's pic.

In the foreground is the fuel pressure sensor on the common rail. Behind that is the hole for the boost pressure sensor. The black hole is for the sensor. The threaded hole is for the mounting bolt. This is all on top of the engine on the driver's side almost at the firewall. A 4mm allen wrench is needed for removal of the boost sensor. The worst part is getting the wiring harness out of the way enough to work.

Matt, no problem...I'm going to take a cover-off pic of the engine bay for future reference.

Photos here: DnA Diesel's photo page - Jeep

As a suggestion, I sprayed some silicone lube on the four post attachment grommets on the engine cover...makes it a lot easier to get the cover off.

I have such a marked photo for my Jetta in my photobucket VW folder.

Cheers
Duey

Well here is my take on this and what I have seen, If you have not done any thing with the CCV ,t he boost pressure sensor will GUNK UP with the system stock every 1,000 with a lot of build up and needing of a good cleaning, now with the ccv mod, every 3,000 is only a slight black powder build up and not sludge up if it were stock. Now with a Chip Tune,ccv mod only a very light powder build up and not blocked or sludged up. I think the best thing to do is very oil change, have a look and make sure its clean.

I do 7000 mile oil changes. Every oil change so far I have had a CEL come on for ...... an EGR valve replacement. This schnit is getting old. I love my CRD but this dang EGR stinks.
