After capping the first oil pressure restrictor fitting because of how close it was to the engine mount, I ordered a second fitting to install in the other hole. The plug had to be removed, but only with great difficulty. The plug was metric. With Jeff's help, we used the heat gun to free up the plug and finally, got the plug to release. The new fitting was installed with anti-seize and torqued. The oil pressure line was then screwed and tightened down.
