D/DT-360 Cast aluminum valve cover

[bwop2017]

Well, I've been having issues with the valve cover on my 766 D-360 leaking. The original valve cover was rusty on the underside, so I had a friend sandblast it. It was rusty enough that it blew a hole in the cover, we tack welded to get by. 

Then I got ahold of a nice stamped steel one from a truck motor, it has the internal bridges for more rigidity. Lately it's been leaking and the problem is the cover will not tighten down on the gasket, its still loose in one or two spots. I'm thinking its tweaked, I've had it loose a few times and just get it to sit right, I've tried a hammer and wood block to tap the valve cover in, but it just wont seat. 

So, I've been looking for a cast aluminum cover. They were on the last year DT-360 motors '94 or '95 I think. I've checked a few salvage yards with no luck. There are places that make billet ones for some pretty $$$. I don't know if atlas tractor would make one but I can't get ahold of them. I would like to get a cast one from a truck/bus so it doesn't look out of place.

If anybody has a lead or knows somebody that has one I'd be interested.

That cover has metal "guides" that fit inside the head to hold the cover aligned

common for the cover to get spread too wide and be difficult to get into position

Try to fit without a gasket -- see if the cover drops into place
I have used a vice to squeeze the cover a little -- and use a straight edge to check your work

Hammering is a nono so stop that

I know which guides/lips you're talking

You cant squeeze this valve cover, it has bridges spot welded inside of it to prevent it from squishing/spreading.

I'm not beating the piss out of if, just tapping from the outer rolled lip to see if I can get the lip to fall inside the raised surface of the head. it wont seat just to the rear of injector 6, its too rigid to work with.

If its just one spot, can you grind off that one tab so it sits down?  may need a little more care getting the gasket aligned, but would work?

Curious if that is an aftermarket cover
I have never seen cross supports on a 3 or 400 series valve cover 

Retainer bolts have been torqued too much and caused the cover to spread
or it was built tight in the first place
usually there is just a little side ways slack
