Engine stop

[musicaldoc]

I have a MY 2007 Liberty, is it normal that when you turn the key to the off position the engine rumbles (that's the best way I can describe it) for one second before stopping?

Now I'm becoming aware that it makes a kind of gentle "SBUFF" noise after the rumble...did you ever notice it in your 2.8 CRD ?

The "SBUFF" (great description, BTW) noise is normal.

I guess it should be the pop-off valve action, but why it can be heard sometimes yes and others no ?? I'm somewhat confused...900 miles without "SBUFF" and now it comes out.

Hmmm, 13000 km on mine and never noticed "SBUFF" noise... Maybe I'm just used to diesel engines?!?

Cheers,
Gige

Does your CRD start and stop smoothly or with a short rumble-rough action?

Yup. It's smoother during shut-off when the engine is warm though.

Marlon, I'm used to WV diesels which shut-off immediately when you turn the key.

My KJ at the turn of the key shakes for one second with a "TROTROTRO" sound...befor the famous small "SBUFF" (you know I like to describe sounds )...I'd like to find out if it's ok...I have to record it and find the way to post the MP3
