I would be nervous, especilly only getting 20 PSI idle with the engine cold. I suggest the following:

1) Get another gausge just to make sure yours is working properly. 2) Inspect the oil pressure relief valve and spring. Only time I've seen them cause a problem is after tampering, but hey, you never know! 3) Don't waste you money on oil thickeners. 4) Is the engine full of crud and other nasties inside? Were the heads recently pulled? What was in the rocker area? The "Black Death" can clogg the oil pump inlet screen. Unfortuantely in the Water Boxer this mean tear down. 5) If none of this helps, next decision is which repalcement route do you choose? All rebuilders except for VW will reqiure a rebuildable core. If you wait for it to throw a rod, you will get to pay that also. If you are considering another engine or an upgrade to a used 2.1L,then I guess you can wait.

I recently installed a wet oil pressure gauge to find out why my oil pressure light keeps flashing.

When I first start the engine, 20 psi at idle and 30-50 on the freeway.

After 3 miles of driving, 5 psi or less at idle and 20 psi on the freeway.

I guess about 40-60 psi on the freeway going about 60mph is nice, but it's consistently at 20psi. Driving home on residential streets at 30mph, I get about 15psi reading.

I'm running 20w50 oil with viscosity thickener.

Should I still drive the van around with the family, or is this oil pressure so low that I should be taking apart the engine? I cleaned the oil relief valve/plunger. Should I stretch that spring out more?

1983.5 Westy with a rebuild about 70K miles ago.
