"Leaked" as in the potting compound sealing the circuit board leaked out? In that case, the "leak" probably will not affect its function in the short term, I suspect.Is this part needed for car to run? The old one leaked
Specific function is to prevent EGR from engaging during first ~35 seconds after start up if I'm not mistaken.If the item is the EGR timer, it relates to the emission system. Don't specifically recall what its specific function might be, but if the EGR system is inoperative, for whatever reason, then its function would be minimized, I suspect. Might find more information on what it might do in the Chrysler MasterTech videos at www.mymopar.com, in the "What's New for 1978" sort of video course or one related to 1978 (or similar) emissions system upgrades.
Just some thoughts,

If it's the time delay it's not needed for the car to runIs this part needed for car to run? The old one leaked
So the thermal vacuum switch (which opens after the coolant reaches a certain temperature) that runs the EGR vacuum was deleted? EGR is normally closed at base idle anyway. One more trick to get the emissions levels produced "to pass".Specific function is to prevent EGR from engaging during first ~35 seconds after start up if I'm not mistaken.
