Need Non-Mopar Help

Shouldn't be a 5 hour job at all, I do head gaskets in them in a day start to end. Removing the throttle body shouldn't be that hard. You could always pull the top intake off . I do think you have to remove the crossover pipe heat shield(4 or 6 10mm bolts i forget now) and then get to the housing. Still a tight job but doable. Maybe shop around for quotes.

I do know the intake gaskets on them go bad and start leaking water externally or into the oil. If you get that far into intake gaskets do headgaskets. Already have all the pushrods(intake/exhaust different lengths), rockers, valve covers all off to change them. Head are one more step.

That being said all new stuff is build like this. Work everyday in a garage and cars keep getting worse.
