TRANS WAS SEPERATED FROM ENGINE!!!!!!!!!!

the diesel vibration and spinning convertor was causing the entire trans to wobble left to right, and cross wobble side to top, and side to bottom.. ALL THE BOLTS NEEDED EFFORT TO REMOVE, so im assuming they stretced over time..

hence why i couldnt pinpoint the rattle

so after checking convertor and flex plate alignment and secureness, couple hours removing bolts, matching them to grade 8, applying blue locktite and retightening, no more rattling...

so...

off i go to where i left off before all this happened, to look for injectors , which are worse now due to my WIF issue recently, and exhaust system..

thanks you guys.. for dedicating time to help me out on this one..

Yep Great news. And to remind you, myself, and everyone else, It still beats that new truck payment hounding you everymonth, compounded by an Exise tax bill for another G.

My Bad, I should have included in my Flex Plate description that the reason the flex plate broke was because the tranny bolts were missing/broke/and loose... Damn PO!

I am very glad you found the issue before permanent damage was done. Keep an eye on that flex plate though since it has probably been stressed from the off axis movement.

yah, i took a look up there using a borescope for one, slowly turning the flex to see its circumferance, took my time on that part.. but it checked out ok,, but you never know..

I looked all over town for grade 8 type metric bolts when I was trying to mount the engine on the stand (metric grade 8 bolts are called 10.5 or some such weirdness). I never could find any, so I used grade 5 (8.9). 3/8 SAE will thread in without doing too much damage. My engine builder had my engine mounted to his stand with 3/8 bolts when I went to pick it up, :mad2: but the metrics went right in afterward without too much fuss.

The extra grip from the threads not being quite the same might keep them from backing out again. I think I'll put some medium Loctite on mine if I ever get the thing back in the truck.

i just called the local privately owned AP and told them the sizes i needed in grade 8, and yes.. they are actually 10.5 hardness due to the metalurgy of the metal when its that thick, or something like that.. who cares.. lol, :thumbsup: but the poor guys there took about 3 hours to find them, which is the time i used to check the flex and convertor, im just glad my internals are good
