My I/C system has had 2 kinked hose locations and all three FMHE thread fittings leaking since it was first installed back in 2010, a while before the motor tear down. It had always been topped off daily with water, ZZP jew'd me with black rubber hoses in the S2 kit, so it most likely never got all the air bled out either. Pump connection got enough salt water exposure to corrode away the connector pins, come winter 2010.

I installed a new I/C pump a few days before I did my injectors back in June 2011, I only filled it once, barely bled it initially. Next time I checked, the level had dropped more than the usual bleed cycle, so I checked for leaks. There were no external leaks anywhere; besides the seeping thread fittings, so I drained the whole system and condemned the core.

End of August, replaced the I/C core, modified FelPro S/C gaskets to match the I/C core and ported LIM, replacing the POS garlocs once and for all, ran all new silicone hoses, resealed the horribly sealed plates, and applied paste to the threaded FMHE fittings. As you can see, it is all 50/50 green now and ready for winter.

I'm thinking and starting to agree that the I/C core tube probably got damaged moving it sometime during the cam tear down, in January..
