Got the cam cover on the other night. I used my homemade com cover tools to just get things started, then just followed the tightening sequence over and over again to slowly and evenly tighten down the cam cover. I tried to keep an even gap all the way around as I tightened down the 40 cam cover bolts. I didn't have any torque wrench that went is low as 13 ft lbs. So I just snugged each bolt down tight as evenly as possible by hand. I used the mini-roller to spread the gasket sealant that came with the Fel-Pro gasket kit, a small tube, and there was just enough to get a thin even coat on all the surfaces of the cam cover.
Just placed an order with IDP for a turbo bypass valve. I'm glad I pulled the turbo and inspected it, but I think it's going to be a pain getting the turbo back in.
1996 850 Turbo Head Gasket Replacement
I promised pictures...
Picture of socket wedged in # 4 intake.
Close up, you can see where the socket ate into the wall a bit, shiny spot near top of the socket.
Somebody's lost socket, a 12mm 12 point; mine now.
Head ready for machine shop.

Anyone know what these o-rings go to? They came with the gasket kit and are in their own separate bag. I think it's the "2 Installation Aid", all the other gaskets were just loose in the box except fuel injector o-rings, they're in their own bag.
Started the car last night, no CEL or any other light. She started right up and idled fine. Lifters were noisy though. Before I could start her I had to pull the new heater hoses out of the firewall and get a short piece of hose to by-pass the heater core. As I was filling the coolant reservoir with plain water the heater hoses were leaking at the firewall. I filled her with water, got her up to operating temp, shut her off, let her cool down, drained the water via the bottom radiator hose, filled her again with water, got up to operating temp, shut her off and left for the night. Tonight I'll drain the water again and fill her with coolant. The temp gauge stayed right at the 3 o'clock position the whole time she was warmed up. Lifters were a lot quieter the second time I started her.
Unfortunately, I'm concerned that it might still have coolant leaking into the cylinders. On start up the exhaust is clean, no vapor. Once the car warms up the exhaust has a white vapor to it. I had the garage door open and it was in the low 60's upper 50's outside, so maybe the vapor was from the hot exhaust hitting the cool night air. I'll find out tonight when I take a test drive, if she over heats then all that time and money was just a good learning experience.

Atypical smoke and steam is expected after a major overhaul like this. Thick heavy smoke and steam is not typical but light smoke or steam is pretty much expected.
After you get the car up to temp and put a hundred miles or so on it everything should burn off and things should go back to normal. After the exhaust gets good and hot it will burn the residual stuff off.
The lifter noise is expected as well and it too should go back to normal.

Ditto what Lee said: after working on mine it took 50+ miles to feel and act normal. Perhaps the computer relearns some startup conditions? In any case, they seem to come right after a few miles. Report back in a bit, and congrats on finishing the job! That's a major success!
I think it may be good. Drained the water from last night out of the coolant system and refilled with coolant/antifreeze. Started up and let her idle up to operating temperature. Checked tire pressure. Then drove to a nearby BP for 10 gallons of Premium. On the way back to the shop the low coolant light came on. Filled reservoir to midway between low and high marks, looked for leaks - found none. Drove the 8-10 miles home keeping an eye on the temperature gauge; it never moved from 3 o'clock. Took it easy and kept the RPMs under 2k. Checked coolant level, still above min level. Checked the exhaust, no vapors, lifters sounded normal, engine sounded smooth. Later I drove her to a fiends place and got handshakes from real mechanics that were genuinely impressed that I actually was able to replace a blown head gasket.
Plan is to put another 10-15 miles on her then change the oil and filter. And I have the heater core supply/return line hack to do. There's a few other things to fix on this car; odometer, speedometer works sporadically, ignition is loose and needs to be jiggled to get the power to come on. The journey continues.

2 week report. Car is running great, great acceleration, smooth, and quiet. Changed the oil and filter. Went with Rotella T6 5w-40. Still have to do the heater core coolant lines hack and fix the odometer/speedometer. And the drivers leather seat is shot, starting to split in several places; I need to do something about that to.
The upper oil cooler line to the radiator leaked a little bit at first, I had a zip tie on the connector from when I replaced the the radiator in June. I put a small hose clamp on it and that stopped the leak. Same thing happened on the upper transmission cooler line, but that line already had a pipe clamp on it - which I just tightened a smidge. I need to replace the o-rings on those cooler lines. But no more leaks for now.
