95 Mercruiser 4.3 water in oil

Ayuh,..... Without usin' a rubber washer, water will chase the stud, right down the intake,....

Don't agree, but all good. Rubber washer fits tight on stud. Nut a washer on top squishes rubber washer, like factory plastic lid.

If we get down to it, sit a bowl up side down over the flame arrestor when its buttoned up

Ayuh,..... I think we Do agree,.... even the plastic covers can / will leak, without a rubber washer,.........
An o-ring is barely a "til I can find a washer" fix,....

This is from my 1990 4.3.

yes, I have the same cover but it has cracks in it. I'll have to consider getting a replacement.
