I just removed my covers and noticed no gaskets or seals other then the 1/2 moon seals.   no apparent leakage and no signs anyone has been inside this motor before.   Were there any years or series engines that did not have them?  Maybe I got a Monday car!  Any input guys?

JDM motor,  Appears to be very low mileage based on all evidence   everything was on the motor as far as I could tell  All plumbing was in pace,  all wiring was in place all accessories were ther,  just no evidence that the motor was ever screwed with  Every other item that i have pulled off (replacing oil pan, pickup tube, water pump, timing belt and bearings, thermostat, etc) has had all spacers, bushings, o rings, 1/2 moons, and gaskets  and no signs of wear   That's why I was interested  It might have left the factory that way as a mistake or someone may have had a reason to look under the covers, or some sort of factory change for a different year or series   No evidence that there was ever any leakage around the cover   So is the opinion that should i assume it needs a gasket (i have a full set on the way)?  No the motor has not been run since i received it

OK so if you flip the valve covers over, there is a channel around the edge that is about 1/4" wide which is where the gasket goes and what I am gathering from what you're saying is that there is nothing there. Is this correct?

 

I am pretty sure the oil would have leaked out as mine was leaking slightly on the exhaust side with a gasket. So either some one took them off before it was shipped to you or you have magic valve covers.
