Head gasket options for high boost OM603
Head gasket options for high boost OM603
Yes?
No?
They say with composite gaskets its not *necessary* but that's also DEALER advice (ie. extra unneeded labor at stock power level with stock stretch bolts). The dealer would love to not have to go back in and pull camshaft just to tighten some bolts... hence the weaker head bolts I believe. Now with stronger studs, I'm wondering if maybe the gasket-fasteners-head is/are relaxing and I lose a gasket after some time.
Cummins guys swear on hot-retorques but they have iron heads. Aluminum heads that a no-no and should be done cold. I'm thinking about incorporating a re-torque into the head gasket procedure this next time after a few *easy-going* heat cycles.
Thoughts?
