Post subject:  No vacuum since yesterday, and no power at all.....
:shock: All start (noticeable) with my A/C that did'nt work for the front vents in the dash, OK, vacuum problem to works the vents, that goes me to another and more big problem, since a week ago I was noticed less power in my CRD, and after a thought, I guess this vacuum problem is killing my turbo also, I stop immediately the CRD and notice oil for the area close to the Turbo. Is my first real problem with my CRD (68,000 miles), and I was reading about EGR, etc. Please anyone that can help me with my first step???

Thanks in advanced

Luis from Puerto Rico.

Post subject:  What model
Hi, Luis. You didn't mention in your post what model CRD you have. I assume you're driving a US-Spec Liberty (either 2005 or 2006 with a 2.8l CRD). Are you more worried about the loss of power or the Air Conditioning not working properly. They may be related but they also might not.

I would start with finding the location of your oil drip (using a flashlight, etc). That's a good first step in troubleshooting.

My model is a 2005, I started 5 minutes ago washing with degreaser all the area, I can't say if the two problems area related, but may be, since the Jeep feel strong a week ago, with 25 mpg of efficiency, and no visible smoke in the exhaust, then about 4 days ago, I started to feel that there's no power and need to use more "gas" in the pedal to achieved 50 or 60 mph, and started to notice the dark smoke existing the exhaust. I use 50 to 70 % of Bio diesel, although right now is less than 25% and I guess this is not the problem, the Bio is a good quality, washed, etc. This week when I noticed the loss of power I changed the Fuel Filter and Air Filter, but the problem persist. Some friends in a A/C shop tell me the vacuum pump in the right side of the Jeep (above the right wheel) isn't working, but they didn't detect grounds problems in the Fuse box. Maybe this needed vacuum is the key problem because I know in some way affect the performance of the turbo (smoke).

Post subject:  are you seeing any trouble codes?
Out of curiosity, are you getting any trouble codes (via scanner)? It sounds like you may have a intercooler hose with a leak. It would be a very common thing for your jeep's age.

Try taking off the hose that goes from the turbo to the intercooler (large diameter at the top of the engine just to the left of center looking at the engine from the front). It's probably has a good deal of oil inside it and if you bend the hose around in your hands, you may find a weak point or split that is allowing boost air to leak out when your turbo spools.

There may be an issue with the turbo, but a cracked hose WOULD leak oil, and it's easy to find, so check that first.

Check out the threads on "SAMCO" silicone hoses. They're pricey, but not much more than the stock rubber ones. Also, check into putting a filter (either a home-made or MANN-Provent) on the crank-case ventilation. That will stop the oil from going into your intercooler (and your intake).

About 2 hours ago I repaired the damaged gauge, how???, well the part affected was the "turbo end", I bought a Turbo Hose from a close Turbo Store, and use the gauge thas was good with a metal tube modified by a muffler shop, and voila. And you know how much for the new gauge from Mopar??, $290!!!!, how about that!!!. Well my situation is that after I made the reparation, the CRD feel strong again with no dark smoke exiting the exhaust. But figure out that this don't solve my problem of the A/C. The vents in front of the Dash still sleeping, the air goes out for the vents close to the mirrors. What can I check now???, Another leak??, the Vacuum pump above the right wheel??, all looks clean now. As a matter of fact, I never until today made a Full Trottle to the CRD, but today testing I done it and encounter that it didn't pass the rpm above 4,000, the CRD don't hesitate but don't go above that mark. Thinking about it, the In-Tank Cummins pump?? maybe the solution???, well anyway, I need to solve the A/C problem first. anny suggestion???

Thanks in advanced

Luis.

Luis; a lo mejor tiene una mangera de vacuum roto. Sin vacuum el turbo variable no funciona en absoluto. Tampoco el selecionador del ventilador ni el multiplicador de los frenos. Las bombas de vacuum casi nunca fallan de repente, asi que, probablemente tiene una manguere suelto en algun lugar. Deberia escuchar para un silbido probablemente en el area del controlador del turbo al lado derecha del motor.

Ok, I'm gonna look more further, Luis.

Nothing wrong, at least visual from the vacuum box to the brake system and EGR, unless the damage were not visible into the hoses protectors, but it supposed to be fine down there. Just need to check the line that goes to the A/C into the car. To be continued...

Have you pulled one of the vac lines to check if there is any detectable vacuum?

Yes, but nothing at all, I clean all the area, all looks fine, I removed some lines trying to figured out, but nothing appeared until now. I use the Jeep two hours ago, and it works fine with no hesitation, also I can hear the turbo when activated in aceleration!!!, that's normal without vacuum, also the brakes feels normal. When the problem with the A/C began, I start it On and Off that day and after that the system works normal, then when I shut the CRD in a Gas station the A/C just works for the defrog area. I was hoping that the reparation of the hose from the turbo to the intercooler solve this problem also, but that was not the case.
Thanks to write and sorry for my problems. Luis.
