DIY reverse intake manifold valley cover???
DIY reverse intake manifold valley cover??? Ive seen some people speak of cutting/welding the oil pressure sender boss to clear the manifold. Is it possible to cut it off and grind smooth and install the Katech piece?
or maybe the one like it from SMC?

Yeah, those kits are for the whole valley cover. I already have a new one, so I just wan't to grind-r smooth and install the flat adapter. They're not too expensive as they sit. I could cut/weld as well...but I'm not really that good...lol I guess some shorten and re-tap, but I think the LS3 manifold is a bit too short for that.
You can put on a totally flat valley cover from the non-AFM GenIV trucks (it's cheap- like under $40) and then get a GenIV AFM driver's valve cover and use that as your PCV source. That's cheap and clean!
If you don't want the PCV port on the driver's side, you can swap the driver's and passenger valve cover. Whatever works best for your packaging requirements. I don't think the engine knows the difference.

I did just that myself. I cut the sender boss off and then sanded it smooth. I purchased the Katech adapter and mounted the ls3 intake in reverse. I still didn't have enough clearance so I had the mounting surface milled slightly so the Katech adapter would sit a little bit lower. Cost about $50 to have it milled.
I see Katech sells a new "very expensive" adapter especially for a LS3 intake.

Sweet, thanks for the pics. I might just have to grind it smooth, tap for a 90 and adapt for the sender. It will probably be 4" long..ha!
Anybody off hand know the thread size on the sender? I'm to do a search...

hate to dig up an old thread, but you just milled the OPSU port off yourself KENS and installed the katech adapter? Any alternative options out there to that adapter because katech is RIDICULOUS in price.
I cut the port off then carefully sanded it flat. I then marked where I wanted it milled down slightly. I then took it to a machinist. The interference is the worst with a LS3 intake if you are reversing your intake. That is why Katech came out with the second style of fitting. It's twice the price. I actually just bought one a while back. You don't need to grind the bottom of the plastic LS3 intake with the expensive fitting. With the cheaper Katech fitting I still needed to grind a bit of the plastic ribs on the bottom of the intake manifold.

Are you reversing the intake manifold?
One of the fittings (the cheaper one) is for LS2 or LS7. The more expensive one is for LS3. I've used both with LS3 intake manifolds.
Both of these fittings are primarily for users who reverse the intake manifold.
If you are just looking to use an aftermarket oil pressure sender then there are cheaper options.

Whats the reason for two different adapter fittings if the valley covers are the same? That's what ive been curious about.
