Those head bolts are torqued to 205 lbft.  A 3/4" breaker bar with a 3/4" socket should do it. 220 lbft is the highest i would go, when going back together, but 205-210 is plenty. Do you have the torque pattern, and it is 3 rounds tol done..

Will take time, not sure how fast it will happen.  I have legs made up to get it off the floor and I can drop the pan.  Local guy has std pan that he will trade for my ESI pan(that won't fit my chassis).

 

Found a couple loose exhaust rockers(like more then 1/8" lash)hope that isn't a cam failure!  Didn't make any bad noises while running and had 70# oil pressure.  Will investigate that further.

My 3/4" IR won't break the head bolts loose, but was using adapter for 1/2" socket.  Need to buy a good 3/4" socket and see if that improves the performance.

 

Should have some updates next week?

 

Just run the over head and check not the hard! Loose means nothing unless you’re on the valve set marks! That space is there to make the engine brake function! 220 is bolt tourque that said as Joey mentioned top end with studs ! Esi Engine 53 quart pan!

No engine brake(dynatard) that I'm aware of.  I would assume, like a gas engine, that even at TDC there should only be max clearance(.020?).  Not +.150.  all the rest that I could check without rotating it, were pretty close to .020 sumthin.  Going by "feel".

It's coming apart, so I will make sure things are okay.  Could just be lack of maintenance.

Have to wait to get engine on legs, as it is just sitting on a few pieces of wood.  Any big bar will have it laying on its side, on the floor! 😨 

 

I remember the 673 was like 150#? when I replaced a few broke studs years back.  At least that is what I pulled it to because that was all my torque wrench would go.

I cant post the picture of my book. So here ot is for head bolts on your tip turbine.

Lightly oil the bolt threads, amd washers and the top of the holes in the head. Not the block threads. 3 stages of torque is , 50-125-200 lbft. .  I wish i could post the torque pattern. I will try again..
