head gasket question
i was driving my truck tonight and when i got home i went inside and realized i forgot something. go back out and i see antifreeze on the ground and see its coming off the oil pan. i trace it back to a few lines coming from around the #5 cylinder where the exhaust manifold bolts on. i put my new turbo on and hammered down on it a few times during the week. i pegged the guage 2 or 3 times at 35lbs. any chance in heck that i didn't blow my head gasket and if i did, how much does it normally cost to fix

mine leaked in the same place, was running hotter water temp, it even steam cleand my block.
when the engine cools off if its leaking antifreeze into the cylinders it will pull the water into them, but mine seaped out the side under the head and still ran fine just couldn't tow with it
and i bet you were pushing alot of boost with that set up so you might have blown yours if nothing eles is leaking

compression test uses a compression tester and adapter in the injection holes.
a leak down test pressureizes the radiator to see if it leaks down(losses pressure)

8hours sounds about right for shop labor (remmeber, they dont work for free, so they pad the time when possible). It took me about 6 last time, no lift, no cherry picker, no helper, in 20deg and wind. If you have a closed shop and a cherry picker, you should be able to get it done in 5-6. Check the head for flatness.
Head gasket set is about $150-175, and includes EVERYTHING you need, and a lot of stuff you dont if you arent rebuilding the head. If you have a stock head gasket on your 90, I'd bet you blew it with 35psi boost. The older original gaskets werent as strong as the 91.5 and up intercooled gaskets.
You can reuse your old head bolts- check them on the gauge that comes in the kit to make sure they havent stretched. I had a few that wouldnt torque down, so I replaced all of mine in 2007, and it was a little over $100.
Get the kit from Cummins, nowhere else. I have seen a commparison of Cummins vs Felpro, and there is no comparison. The Cummins gasket may be over-engineered, but that's a good thing.

You can try retorqueing it to see if it stops leaking, but I wouldn't bet on it.
If powertripls1 has time to help you, I bet you guys could knock it out on a Saturday.

I think its time to upgrade to a 60psi boost gauge too, it could be running just 36psi now or 46psi. Who knows. lol
