"Marbles in the motor" sound??????

[apextrans]

I know i've seen something about this on here before. I hear it at ilde. Sounds just like marbles rolling around & clicking together. What is it or What does this mean?

Injector would be my first guess.

Currently with my DD, it is the marble Nicole left in the cup holder of the car seat!

Check your timing, if injector timing is off it can sound like that at idle.

Another thing to look at is the cold start advance, mine clatters like a can of spray paint until it kicks off.

could also be a flywheel, they make a terrible racket when going out

duhh... oh well we all need a laugh at my expense, i'll read more before my next post

my buddys PSD sounds like that but his is the torque converter the only other thing I could think would be the vacuum pump

I noticed it after the cold advance kick off. I'll check it again in the morning.

WAV file?

WAV file?

Ummm...are you joking!?!? I'm lucky I can log onto this place. Seriously, I don't have any idea how to do that or the equipment to do it with. I think my timing may be off though. I've lost a few points on the SOTP gauge & it doesn't sound right at ilde. Would the truck have started at all if I was one tooth off when I put the truck back together?

Off topic, but did you ever get your axle fixed?

Scott, maybe you can make the meet in York Thanksgiving Sunday. Check the BOOB for details.

Which truck is makin the marble sound. Mine did it after I put the new TC in that was about 100,000 miles or so ago and still sounds the same with no problems

Can you isolate it to where on the engine you hear it? How about removing accessory belts one at a time to rule out those possibilities?

my vacuum pump did this also
