I'm sure the answers exist to my questions, but couldn't find exactly what I'm looking for, so forgive duplicates (newbie forum member here).

Background:

• Religiously serviced 2004 Range Rover
• Blew first engine at 86K miles (apparent oil pump failure, which led to catastrophic engine damage)
• Replaced with remanufactured engine
• Now at 122K miles, engine has severe, loud "ticks". Only one cylinder is firing properly and producing compression. Local (reliable) shop in the DC-area (Bethesda, MD) advised to send truck to salvage (not sure why, as no one owns an RR based on a cost-benefit analysis. This shop refurbs loads of Defenders, so can't discern the aversion to "simply" replace an engine on a RR)
• Abhor the idea of trashing my truck that's accompanied me to multiple countries; plus, don't want to give-in to "throwaway" culture. With that said, it's really irritating to be evaluating a third engine when my '93 Isuzu Trooper gave me 500K miles of excellent service before it gave up the ghost

Questions:

• Where can I go for an alternate opinion / engine replacement in the Washington, DC area (or beyond)?
• What considerations should I be giving to this decision (I'm clearly clouded by nostalgia)

Many thanks in advance for your help!
