Default G8 DOD valley cover

Just wanted to save yall some time if you decide to go with this cover instead of the truck dod vlom. Its built alot better than the truck version, and is more low profile, the oil passages are alot better as well. You only need basic hand tools to take it apart and do what you need. (angle grinder, drill, etc...)

some things that are diffrent are the DOD connector and tray assembly,

shown here







Anyways heres how you dissasemble it.

start by cutting the rivets off on the tray assembly.






like so..







You can now seperate the assembly, (do not pull by the solenoid tray)




Hit the ends of the rivets with a hammer lightly and they will pop out




I used M6 1.00x35MM from ace hard ware its a perfect fit and there low profile youll need 11




If your using this VLOM with a LS2 or FAST Youll need to chop it down and re work the oil passage into the DOD tray. I did it with a hand held drill and a drill bit, nothing fancy just take your time, and remember its aluminum.

Started with this



Ended with this

If youre not using the VLOM connector or anything use a metal button 7/8ths to cover the hole up.

here are the finished pics





the new screws

Please elaborate further on where and how you used the OPSU sensor with this. Since it's shaved down so far and based on how fieroguru put his together, I have a feeling it needs to be relocated somewhere. But where? Is there no room to have it angled? 30° or even less?

Also, did you use any nuts with those bolts/screws? Or do those screws thread into the aluminum?

Refer to this for the relocation , if you don't wana go that route you could try and reweld but I don't like the way it would have to be done.

These pics should help the bolts go in place of the rivets. And washer nut on the other side.

Its also worth mentioning use either loctite or locknuts during reassembly.

Oh so that's why you bought that Glowshift plate. Does the OPSU harness make it down by the oil filter or did you have to extend it?

I guess I'd use some nyloc nuts.

I just have to get the DoD connector extended and flattened and get an adapter for my throttle body harness.

I tried peeling it back out the harness but it was all kinds of twisted through. So chopped off the connector and soldered on about a foot extra worth of wire to reach down below

Thanks, I'll probably just get an extension harness made.

What welding machine are you using to weld the aluminum? Will those cheap aluminum eBay units work?

That's all tig weld. And given the pressure this particular area is under I wouldn't try anything else. I've had issues with using mig on aluminum before which is is why I'm doing it right this time

What head gaskets is everyone using? The LS2 (P/N 89017585) gaskets or the LS4 (P/N 89017769) ones?

I'm specifically talking about the manifold to cylinder head gaskets.

Are you referring to the intake manifold gasket set or actual head gaskets? If head gasket you'll need the LS4 since there's a difference in bore size between the LS2 and LS4

You'll want Whatever manifold you're swapping to. I.e LS2 use ls2 gaskets, LS1/6 use those.

I purchased the Glowshift sandwich today but then quickly called to cancel my order.

Why didn't you go this route (far left) instead?





It comes pre-drilled and pre-threaded; all of our sensors are the same and this attaches the oil pan. In fact, it's visible in one of your pictures.

P/N 12551587

The rest of the LS family has different entry shapes and overall size off the opsu housing. I already went this route after ordering a ls1 and 2 block off plate and either the bolts won't line up or the port doesn't line up. Hence why I went with the glwshift adapter.
No drilling tapping nothing.

I still have the corvette opsu and here's a side by side. The ls4 housing still has the adapter plus opsu in it.


Side by side
