I've only had my 06 crd 28000km, for one week, but under hard acceleration i'm hearing a lot more wooshing sounds as well as almost a tappet type of rattle until the revs come up some. Being new with this jeep, is this normal or not. Thanks for any help. |

Trying to decode your verbal description with a Diesel will: 1) Make you worry for nothing 2) Tell you it is OK and you trash your engine. If you have a friend who owns a Common Rail Type diesel ask them to go along for a ride and listen. Common Rail Engines in US and Canada are: Newer Dodge Cummins trucks (I think 03 up), Duramax engines, Sprinter engines, Mercedes CDI engines including the Jeep Grand Cherokee. A good mechanic who works on the engines above will be able to tell by listening. Another option would be to record the sound, post it on U-tube, and post the link, we will be happy to help you. Also I recommend you read and act upon some of the other posts like the ones on ORM and SEGR so your friends will say,"Diesel EH?" instead of,"Is that a Diesel?" Then Clean the MAP, and pick a lift pump out after looking over the threads. GMCTD's Haystack in the CRD Tech Section has an abundance of great information. Your fuel economy will benefit too. |

Well I may have an idea as to what these bad noises were. I tried the ORM and the difference was amazing. No more rattling under acceleration, and the engine felt much stronger. Maybe the egr valve was the problem. |
