Alternatives to the 1HD-FT crossover pipe/valve cover insulator

[kenavt]

Hey folks, I'm curious if anyone has found an alternative to an OEM part for the 1HD-FT's crossover pipe to valve cover insulator (OEM part number 17117-17020). It's NLA from the typical suspects (Partsouq, Amayama) and is just a foam spacer that sits between the air intake/crossover pipe and the valve cover. Mine has become oil-soaked and gross after a double whammy of oil in the intake from blow-by (catch can installed), and a bad valve cover gasket leak (now both getting addressed).

This part feels like something that should be easy to cut from a larger generic block of foam - if you can find the right foam material or compound. Has anyone tried this?

You could just use some closed cell EVA foam.

In Australia, 10mmx100mm rolls of eva foam is readily available in hardware stores for use as an expansion joint for concrete.

Glue layers together as needed

I had not heard of this before - sounds like a great idea! Water-resistant, chemical-resistant, large temp range, meant for outdoors use. Unfortunately couldn't find it at our big US chain stores (Home Depot and Lowes), but just ordered some online to try. Will report back how it compares.

Any luck?

I spent a while Googling, and ordered some of this foam on a whim (way too much material but seems like the right direction for foam) and it's sitting in my garage, but haven't tried it yet. Seems like it'll be okay texture-wise but I don't know how it'll hold up to heat or moisture yet.

I glued this foam together with some Gorilla Glue-branded spray contact adhesive; and it didn't destroy the foam. The total thing is a bit taller then the insulator foam I have; but compresses down just fine to fit under the crossover pipe (albeit requiring more force when bolting in the crossover pipe). I've had the truck idle for 15 min in the driveway with no ill effects; soon I'll start driving the truck regularly and I'll keep an eye on it to see how it wears.
