#36 of 92 2004 caravan, engine wihring noise by 2761 Jan 11, 2008 (9:41 am)
I have a 2004 dodge caravan with a 3.3l. Engine is usually warmed up for approx 3-5 minutes prior to driving and makes no noise. When driven there is no noise until you slow or stop the vehicle then a whirring noise begins and gets louder as engine RPMs increase. Noise will eventually go away, after approx 10minutes of driving and will not return. This sounds like a pump cavitating, I checked all fluids and they are all full. I also had an engine code for evap. emissions system. Any advice?

the power steering noise makes the most sense to me. Thanks for the comments, I'll let you know. I usually deal with heavy equipment, this is somewhat new to me. Thanks again!

Replying to: shipo (Oct 15, 2007 5:41 am) I had a similar noise which eventually turned to a louder more scraping type sound on my 99 3.8 Grand Voyager. Several mechanics could not locate the problem. As it turned the noise was the camshaft which eventually broke. I have researched and found many other 3.3 and 3.8 with similar problems. I would have your cam bearings replaced. Mine froze and caused a break in the cam and damage to my valves.

Replying to: bobshep (Jan 15, 2008 7:53 am) Uhhh, maybe you have me confused with someone else. My 1998 3.8 liter engine is not making any such noise, even though it has over 150,000 on the clock. That and my Used Oil Analysis shows very low lead and tin readings indicating that my bearings are still in very good shape.   Best Regards, Shipo Replies to this message: bobshep (Jan 15, 2008 8:02 am) xwesx (Jan 15, 2008 8:09 am) bobshep (Jan 15, 2008 8:14 am)

Replying to: bobshep (Jan 15, 2008 8:02 am) I followed it - appeared to me as though you were replying to a post that Shipo, also, had replied. The original poster listed a metallic rattle as his problem. Replies to this message: bobshep (Jan 15, 2008 8:14 am)

#44 of 92 dodge caravan 3.3l engine noise by dcshd Sep 10, 2007 (4:36 pm)
hearing bottom end engine noise only at idle or low rpm. Not a rod noise, thinking might be crank walking. Noise seems to be very close to flywheel. have remove oil pan and looks normal? have not measured end play as of yet but if i pry crank forward and back it seems a bit excessive and noise sounds similar. any thoughts and if thats the problem is it hard to fix?

Replying to: dcshd (Sep 10, 2007 4:36 pm) Is the knock occasional, occasional as in not every revolution, more like three or four knocks and then quiet for a few revs and then back again?   If so then it is considered "normal". I first noticed this noise from the 3.8 liter engine in our 1998 DGC (a virtual twin of the 3.3 engine) shortly after we got the van. Now, 150,000 miles later I can still hear it. The noise hasn't improved and it hasn't gotten any worse, it just is. I'm thinking it might be oil pump related.   Best Regards, Shipo Replies to this message: dcshd (Sep 10, 2007 4:50 pm) 4bigdee (Oct 17, 2007 11:53 pm)
