i got a 94 chevy k2500 6.5 vin f with nv4500 and a dual mass clutch. been fixing things left and right and have been putting this off but has been getting worse over the last 4k miles(only had for those miles)has 242k miles on it. i have a rattle coming from what sounds like the rear of oil pan to the bell housing. its quite loud only at idle comes and goes as it wants to. drives fine idles fine. i rotated crank to see if the crank was broke and i have no slop in it.guy said he had new clutch put in 5k miles ago i have to overhaul the trans per grinding 2nd and 3rd gears when downshifting was wondering if someone can give me some insight that i do not tear trans out and need extra parts i didn't plan for cause i only have one hoist and the shop. i checked the crank pulley its older but not moving an excessive amount i have motor mount on my tool box i will be putting in in the next few days. have new injectors in it as well and is not an injector knock. engine will shake when it rattles to.
any info, heard of's, have seen, thoughts would be much appreciated
thank you for the help,
jon

Made a phone call and got told I should get rid of the dual mass and swap to a single disk right away cause of wore out springs in the clutch if the guy only replaced the disks and didn't do a full clutch kit. Maybe the syntrifical force is enough to make it not rattle at off idle speeds.
Any thoughts on this?
Thanks for the reply:)

drop the manual tranny and fix it . 1994 manual is going to need new springs, clutch/plate and probably a clutch piston.
if they half assed this by just installing the clutch disk then I believe it.
they may have cracked the flywheel when then put the tranny back in because they are idiots...
