Lately at high RPM's I have been hearing a slight rattle which sounds to me like valves rattling, anyone here experience this in their 99?
I currently have about 54K on the engine and am using Mobil 1 10w 30.
All comments and suggestions appreciated.
more likely is the CAT or the heat shield above the CAT.......
I have the CAT/ heat shield 'metal buzz' that occurs in the upper RPM range of 4th gear only. Is this similar?Quote:

I was relieved when I realized it wasn't coming from under the hood!
Might be, I would be pleasantly suprised if that is just it.
Sure sounds internal though.
I will have Gary take a listen next month, unless i see one of you guys this Sunday at the P102 school.
Umm kind of shounds like pre-ignition to me. Try seafoaming it along with some fuel system cleaner and see if it goes away.
Now that you bring that up, i just Seafoam'd the car about a month ago and did the Seafoam oil and gas treatment a couple of months ago...but I always fuel the car with super since it's a little cry baby on anything but super unleaded.
I have ofetn wondered why other people who own the 99's can run regular and my car knocks like crazy on it.
Could the timing get off on a VT car? and if so how would i go about fixing it?
any suggestions are welcome....and thanks
Hmm... my bad rod bearings sounded like a "rattling" noise above 3000rpm... :(
Could be anything, though. We'll look at it this weekend at AX102.
Cool I will be there regardless of whether I get in or not.
