Hello

I am new to the site. I notice there have been several pots about engine noise so please forgive me if this is old news to some.

I have a 2001 XJ8 (3.2L) which has done 70k miles and is in very nice condition. I previously had a 1999 XJ8 (4.2) on which I changed the timing chains and tensioners for third generation so do know my way about these cars but am by no means an expert... I also had a 1968 Mark 2 till about 4 years ago... Too much work to keep happy though!!

To the problem: The car runs well but at around 2000 RPM I get a sort of whurring noise which seems to come from the engine area. It is not tyre noise because I get it when stationary but only bewtween 2000 and 2500 revs. Over 2500 no noise.... under 2000 no noise....

I have read on one site that a similar noise can be got rid of by pressing 'sport mode' but this is not the case with me.

I am inclined to think it is one of the auxilliary plant running from the belt... (Alternator or something) Either that or one of the OHC bearings.

Any ideas would be very greatly appreaciated before I start tearing the heart out of the old gilr!

Many thanks

It is better to keep one's mouth shut and be presumed a fool than to open it and remove all doubt.

 

Does it change with AC on or off? With temperature? I don't know the 3.2. Can you disconnect a nelt amd sww if the noise goes away?

BTW, love your username!

 

Thanks Rob I will try both and post results.

Welcome to the forum! My all time favorite book, BTW... although I think I preferred Mother Abigail. If you've ever been to Golden, CO, it really is a Garden of Eden beautiful kind of place... of course Las Vegas lives up to Randall Flagg's expectations too, lol.

Your devilish noise might be coming from the tensioner pulley - a length of hose, one end stuck in your ear the other moved around the engine compartment when the noise is occurring (use a friend on the throttle) can help you locate the sorcerer... uh, source.

Thanks Again.

An excellent book, I have both versions, the original release and the uncut version. I prefer the original, it's not as dark as the full length version.
It's a great good versus evil tale.
