I'm posting this in 2 different forums, hoping to get a quick response. I have a question on my 2005 VHO. I'm needing new front rotors and pads and curious which ones you would suggest and why? I want to stay away from drilled/slotted ones, have experienced cracking even with the expensive ones but heard that slotted ones work great, whats your opinion? Also, just how big are our front rotors? I'm hearing 12.99 and 13.99 from auto parts stores, which is correct?

UPDATE: The noise finally got more consistant and as it turned out is is indeed one of the cats so I went ahead and had them both replaced, problem solved

Is there a way to check the flywheel or flex plate without having to pull the motor?

03SSBoy, do you have the same issue?

The noise is sort of coming back, not as loud but its there from time to time. I've beat on the cat and it made no noise. Of course everytime I try to get the noise to duplicate for a mechanic it wont, figures huh? I've had it on a lift again and we shook the crap out of the exhaust thinking something was loose but found nothing, really sucks! It isnt missing or down on power but I would really hate it if its an internal motor issue and I end up blowing up the block because its alot cheaper to rebuild it than be forced to replace it. And of course I would hate to pull the motor, get it rebuilt only to find the noise is still there. The part that bothers me the most is not knowing.

Leviser, can you send me a link to the video?

Update!! I'm not sure what in the heck happened but it hasnt made the noise since Monday morning, most bizarre

If it's the cats, which ones would you suggest I replace them with?

Thanks guys, I'll give the tips a try tomorrow morning

Thanks for the replies guys. I cant recall for sure if I hit some water while the cat was hot but I might have, however, wouldnt the truck throw a code if the cat is bad? Live4DaThrottle, I didnt cut open the filter but I have had several shops examine and smell the oil and everyone says it looks great. Also, if a lifter collasped wouldnt it be constant? As to the sound, it kinda sounds more like sheet metal or aluminum vs solid metal, does that make sense?

A few weeks back my truck, 2005 VHO with Magnacharger, 120,000 miles started making a rather loud clacking/clunking noise when I start it up after it sat overnight. I ran out and popped the hood but you could barely hear the noise from under the hood but it was loud under the truck and seemed to be louder on the pass side. I shut it off, restarted it and no noise. The next morning the same thing happened only this time I actually drove it down the road, about 10 yards and the noise stopped. I figured it only did it while it was cold so the following morning I called AAA, put it on a flat bed without ever starting it so I could get it to the shop cold and they could hear the noise. Of course it didnt make any noise so they never got to hear it. The next morning I recorded the noise but they couldnt tell by listining to my recording. Initially I thought it was the O ring on the oil pickup tube because I was told it was a pretty common problem with the LS motors, so I replaced it and it seemed to quiet down for a couple weeks then it started again. So I took it to a shop. At first he thought it was the main bearing clearance but after putting a mechanical guage on it the guage remained stable so he does not believe that is the issue and is pretty stumped, as am I. It only does it when its cold and quiets down rather quickly but this morning it didnt do it at all, most bizarre. Any ideals? Also, are there and performance shops in Southern California that might be able to help me? I figure until I at least get a diagnosis I probably shouldnt take it out of town but I do have AAA Plus so I can get it hauled just about anywhere in So Cal, within reason of course. I'm going to try and attach the file of the noise that I recorded on my android. On the sound file I placed my phone under the drivers side, started it up, let it record for a minute then took my phone under the hood, as I say during the recording, then place it back under the drivers side. OK, it wont let me upload the file, its a m4a file

Also, a couple times, while at a stop light it chugged so I placed it into neutral and reved the motor a little. Then stopped for gas and it died as I was pulling up to the pump, started right back up. Drove another 60 miles home, stopped to recycle some coffee and idled fine. Went back to the dealer and it ran great, hasent died since, that was Friday
