I am leaking a little bit of oil at the back of the passenger side valve cover. I've read about some of these rusting through over the years, and wonder if mine is that way...but I'm currently unable to see it. I've decided to locate replacement covers, preferable OEM style. However, on Bronco Graveyard's site, all the valve covers state they are for non-efi engines only. I am unable to locate them for the EFI 302 that I have under my hood.
Other than a junkyard part, that could have issues that won't be noticed till I spend time removing one from a junk engine, where could I get my hands on a pair of OEM valve covers for the EFI 302?? I'm not interested in milled aluminum, cooling fins, super shiny parts...just OEM steel valve covers.
first thing i would do is try to snug up the bolts.
my 88 diesel needs the valve covers tightened every year or so.
still has the original gaskets on it.
The oil fill and PCV locations change based on application(car vs truck) and EFI covers have a filler neck while carb covers do not. Also when searching online try "5.0 EFI" instead of "302 EFI", same thing I know but search engines are dumb like that.
It's also likely the valve cover gasket is the source of your leak especially if they aren't original, OEM gaskets were rubber coated/steel core that hold bolt torque quite well while everything else tends to collapse over time and eventually leak.

Changing it to 5.0 instead of 302 opened things up a bit. Thanks.
The existing gasket was rubber and came out in pieces. I replaced with cork, which is what I've used in the past with success.
I think I've got a set of OE valve covers off an '89 F150, 302, grey, on a shelf gathering dust. Let me know if you're interested, they're not doing me any good. +1 on it probably being a loose fastener or damaged gasket, though. I replaced the gasket on our Scout 80 and it still leaks a little--more than likely the cover's a little warped where it bolts up.

It's not clear to me why you are replacing the valve cover. I'd first clean it and inspect it before bothering to replace it. I had a great deal of nasty, crusted blackened oil inside mine -- which oven cleaner was able to remove. I cleaned my cover (4.9L), replaced the gasket, and all is well.
