So what did you actually end up doing to fix it other than taking it off and redoing the gasket? We need commentary

89, I love your repairs. I was going to get a gasket to fix mine but I think instead im going to find some silicone

Cool, and those are the better more expensive gaskets too. Doesn't look like you have a bad problem with valve covers leaking though, unless it was in the back of the front. Looks kinda dry by the exhaust manifold unless it was slow enough it burned it off. My 454 is leaking at the valve covers a bit and when I shut it off, its burning off the exhaust manifolds.

Don't mean to be the bitch here, but you know how I am by now. Looks to me by the pic of that head, someone has neglected that motor of oil changes or used some junky oil. Was that you or the PO? Just blame it on the PO wouldja??? I don't wanna hear it was you.

I've never tried Seafoam but this would be a good test to see how well it works. Some before and after pics would be awesome.

The stuff made a believer out of me. As I said, I rarely next to never use additives, but I had to get in on the hype when another forum was talking about it, and then it was on sale at O'Rys one time, buy 2 get 1 Free for $7 a can. I know it makes a differance in the crankcase, and in the fuel and it does clean stuff up, but I am still a little skeptical about the combustion cleaner part of it where you suck it in the vac line and let it soak. Now I know it works for that, its proof positive when you see all the white smoke, but I just wonder if all that junk going thru your cat, if it doesn't damage you cat converter. I have no problem using on my non Cat vehicles that way, but I have to wonder if that's not what trashed my cat on my 93 E-350.

I've seen ALOT worse, not bad for a 20 year old engine.

Ohhh man, you aren't kiddin. I have seen some you can take a spoon and just get heaping spoons of sludge out of them. No, that's not real bad either, but I have also seen 20+ year old motors that are just as clean as a new one inside. That crap is kind of like cholestoral. If you don't let it get started, you're ok, but if you do, then it will just build and build with each time you go to long before oil changes. I run full synthetic in the 93 box van and change it once a year or every 10K miles and the oil still comes out golden. Dark gold, but still gold and not black. A good sign the rings are still in good shape and the crankcase is clean.

i've been able to read the casting numbers on the bottom of the intake... after it was removed. not sure how that oil was draining back, or why the engine lasted that long.

The back lower corner was leaking almost as bad as that blown oil diverter gasket, and this hi-perfomanc gasket is brand new, so the valve cover is beat. SO I just cleaned it up and slapped some goop on it for now, I dumped enough money into this thing this wnter....
