sorry mate, dont have any. .i made my own when i had a sea container by making a three sided cut on the side wall, bent it outwards then stuck flyscreen on the inside to keep insects out
get vents for each side of the container. . allows fresh air to flow thru and they dont protrude outside the ribs . . also rain proof if fitted correctly and the car wont cook
is the engine using any coolant? if not then id just clean the crud off the cap and take it for a looong drive down the freeway to get things nice and warm to evaporate any water that might be in the crankcase
unless you have a blown hg then you wont kill the engine
could possibly be. . the bolts only around a hundred bucks new anyway. . is the new headgasket actually blown? did any water go into the engine when you lifted off the head to change the gasket? if thats the case then you wont have a milky oil cap for long
anyways ralph can help ya! lol
try using 5 star brand spray on degreaser, it has caustic soda in it that will get rid of most oil/grease stains, if you cant clean the floorboards you maybe able to cut/fabricate your new ones?
leaking between the runners would matter as the runner from one would be robbing the intake charge from the other, hence why the gasket seperates one runner from the other
