6.9 reassembly
I am putting my engine back together after removing the cylinder heads to get a glow plug out of the prechamber. I got a little ambitious, took both heads off, started to take the rods off but realized the bearings are good and the rings probably have another 100,000 on them, so I will allow myself to get it back together tomorrow before the weather turns wintery. The only thing I don't have are the head bolts, I have the old ones but want to use new, and since I don't want to wait I will use the old and just not torque them down, slip the new ones on after I get them sometime around thanksgiving...then I will bench test. If any of you have opinions about this let me know, I can use all the guidance I can get. Racer-30 has been a great help and I know he is slaving away getting his motor home back together.

On a 6.9 its a bit more important than a 7.3 because the bolts are smaller diameter, But Again the bolts are Good enough to re-use as long as you clean the threads in the block and lube them with motor oil at the very least.. If you are planning on running a turbo on a 6.9 it can be done safely as long as you stay under 15psi boost. Over that and you better have a backup engine and a friend with a tow truck. Just my 2 cents

head bolts
Thanks gentlemen, got a nice 50 degree day and sunshine, time to get to it. Half of this project has been covering and waterproofing as the fall descends. Must be nice to have a garage with even half a heater.

I'd settle for even a concrete pad to work on, rolling around in dirt and rock is REALLY getting old. So much so this year I finally asked a contractor what it'd cost to put in a driveway, one so short it's barley longer than my pickup. He wants $2,800 + permits. 
Not likely going to happen in my lifetime.

i doubt you would have problems either. I would save my money for fuel.
fyi--if you ever have a chance to get one of those big mats they use at stores by the door they make pretty decent "layer on ers". Easy to move them around and to store. Throw them behind the seat if you need to work somewhere else.
