So, I'm gearing up to pull the intake and valve covers on my Suburban to reseal it. Doing this all in hopes that my slight coolant contamination is from a leaking intake gasket into the valley and not a cracked head. If nothing else I'll fix some oil leaks and clean the egr passage in the intake.
My goal is to knock this out in a day, but will likely have some mission creep and distractions stretching it out to 2-3.
My question: Are any of the intake bolts on the 7.4 TBI through holes requiring sealant? I looked through the FSM and saw nothing about applying sealant on assembly. Any other advice or tips are welcome.
