87 YJ valve cover.

I have an 87 YJ Laredo with the 4.2L, I live in AK, and am having a hard time finding the plastic valve cover. Will the aluminum one from an 86 4.2 bolt right on? Or one from a later year?

No. the 87 shared the valve cover from the CJ's. 88-90 4.2's use an aluminum cover and different mounting bolts. Quadratec sells replacement plastic covers and aluminum covers that are made to specifically replace the plastic ones. Give them a call..

I just got offline with them, they don't sell one for an 87 any longer. I have no idea where to find one.

Here you go
Jeep Wrangler Valve Cover for 4.2L at 1AAuto.com.

I bought this one for my 1990 4.2 and it's works great. No tax and free shipping too.

I had to replace it on my 87 as well. I was lucky enough to get a pretty knowledgeable parts person on the line at the local Jeep dealer and they actually had some in stock, so you might want to try your dealer.

If somebody hadn't mangled my 87 I'd pull the part number for you.

My 87 had a metal cover, not a plastic one.

Funny enough I just ran into the same issue... The reman engine I got was drilled for a plastic cover not an aluminum one even though I ordered the aluminum one. So i can either go with one of these plastic ones or get an aluminum replacement from Qtec..... nother 50-100 I didn't expect to spend

Both styles were available... I think they continued to use CJ heads untill they ran out. The heads are different only in the location and number of holes. There are 7 holes in the CJ head and about 15-18 in the YJ (plastic cover)
