Dang head has to come off, need to know?

My 12.7 DDEC II has to come apart. Coolant blowing out of tank, bypassed air compressor today and with in 2 minutes coolant starts overflowing and pressure gauge would get up past 15 psi. The question is, anything I need to know before I jerk it off tomorrow? I know about the new bolts and the torque is x plus angle, not sure of ft pds and angle though. Looks like the front cover will come off first I guess. I am pretty sure I have some buttons out also so will get them also. I don't have much in this thing and it isn't worth much either. Need to try to get out as cheap as possible for the time being, but time will tell. I am hoping cyl will be ok for now, sure don't need to have to do an in frame with a block cut! Any tricks I need to know before I start? It's in an LTL 9000 so that makes it fun right off the bat! Nothing like a two piece valve cover just so you can get it apart under the cowl! Yee Haw!!! TIA

 

This used to be a sleeper but the bunk has been pulled off and the rear heater hoses blocked off at the split. Is there a air valve in the dash for the cab heat or is it a cable. I thought by the feel that it is a cable. I thought about that but with the rear lines blocked I quit looking, I should have looked under the dash I guess. Before I start stripping I will air up the tanks and turn the key on, if it is an air valve that should show up. Really didn't need this, but none of us need them to break and it is always a bad time. Could have been worse, I had just finished a job that they were holding up my money on till I raised an area that I didn't even bid to do. Had to haul seven loads of fill to finish and it gave up on the way home. Got my money today, at least I have a little cash to buy parts with.

 

Thanks for the tip, not sure I would have rechecked it. This is an old 93 Ford so if it has a valve it very well could be leaking.

 

Ouch, I unhooked the coolant to the compressor--- and put the air line back on, didn't think about that one. It starts pushing coolant out with the air pressure around 30 psi.

 

Just found that thanks thingy, now have to figure out how to use it right. I will check without air to make sure. The last thing I want to do is pull a head and find out it is a $50 valve in the dash!
