Cam Seals Trouble..

[sahtt]

Doing the TB job in its entirety. Used a chain wrench, some serious 'engineering', and a heavy duty torque wrench and the crank nut came off at about 180lbs of tq I'd guess, wasn't hard, did it with no help.

However, I locked the cam pulleys from movement and put some serious torque on the nuts without any success. There is no specific directions for this that I can find in the write-up or searching here or the LS4 forum. I need to replace those cam seals and resync the timing to make sure everything is good before taking it farther apart to replace the tensioners, idle pulleys, and WP.

Thanks for any assistance, looking foward to getting this damn thing on the road.

I was able to finally get it off, although the pulley was not slipping; it wasn't secure enough to let the torque do its magic.
