Post subject:  It sounds like a vaccum leak...

It is coming from the passengers side of the motor.
It increases under acceleration.
Seems to have less power.
When running and listening with the hood up, there seems to be a vibration also.
The vaccun leak sound persists for 10-20 seconds after I shut off the truck....

Any ideas on what I should expect from the dealer...

I had my hands in there this weekend when installing new struts and springs, around the turbo area, seemed to be lots of black sooty oil on the turbo, but I didnt think much aobut it as my mechanic buddy said, "with a diesel, if it is not dripping, it is not leaking."

Guess I am thinking turbo or fuel system, but I definately have very limited knowledge...

Thought I would see if anybody had any ideas, it will go to the dealeer anyhow, i dont have the time or knowledge to fix much under the hood.

are you not running an EHM or a provent?

"Nix" has a great way on making and testing hoses for leaks, you might want to PM him.

I have not dared to do anything under the hood. No ORM, no EHM, nothing. Paranoid about the warranty I guess. ORM is appealing, but having the CEL on all thie time is not. I was going to wait until warranty was up before I do anything under the hood.

I have read about people "purging" filters and emptying water from the water/fuel seperator. Explainations? Guess I need to get into the service manual...


Thanks again.

I am betting that your hose to the intercooler on the paasenger side has slipped off or has a crack. Most seem to be failing at around 2 years/ 30>40K miles.

Sounds plausible... im at 26K, 2 years, and would explain the oil in that vicinity. We will see what the "experts'' haha at the dealership say. Actaully I do not have any complaints aboput my dealership, yet. Warranty here we come...

Thanks

I got to know the tech at my dealership yesterday. He was a really nice guy. Said he was not supposed to replace the hoses until they were "dripping" but he ordered 2 new ones for me under warranty anyhow...

For the embarrassing part :oops: ...found the source of the sound.. So, when istalling the FL last weekend, I pulled/replaced the battery tray and my amazing friend (never seen a KJ or FL, installed both fronts wiht out directions in about 2 hours) pulled/replaced the air box...he did not get the lid seated correctly at the back of the box (hence the vaccum leak sound). Long and short, the tech yesterday said the lip at the back of the box was warped a bit and didnt seat correctly and he would get me one under warranty..nice guy. and nobody at the dealer said anyhting about the lift..

Awesome. Sounds like there are some reasonable dealerships out there.
