i got an 2000 5.3, got it frm the junkyard.an looked at it the manifold bolts broke in the damn head...i tried the easyout **** but its not working =,so can some tell how to get all 8 of the bolts out...

 

Are the bolts broke off in the head or flush with them??

 

one flush n the other 7 arnt...very frm 1/8'' to bout a half inch...

 

for the ones that aren't flush spray on some penetrating lube and carefully try to get them out with some vice grips (works very well).

For the flush one, you need a machinist with an EDM to melt them out (or they might chisel them out and rethread)

 

Ouch...Too bad junk yards don't have warranties!!

 

Looks like a good reason to get new heads to me lmao :smile:

 

Drill a 1/8 hole in the center of the bolt then use a dremel with a tungsten bit and spilt the bolt into 3 and stop short of the threads. I did mine with the head still on the truck not a big deal pretty easy hope this helps.

 

i would of had an warranty but since its not going in a 2000 truck, they wont warranty it..butt really its in good shape rear main seal has no signs of a link...heads like good side them exhaust bolts but i try again n c...wish me luck

 

Its not too bad of a deal man, I know it can get aggravating tho

 

+1, and you could try drilling the flush bolt out, starting small, getting dead center, and being very patient. Keep stepping up the drill bit until you can basically pick apart the remaining thin layer of bolt thread, being careful not to damage the head. I've done this many times, you have to be careful and it's tedious, but it works.
