Lifter is super easy. Just do the long socket extension stethoscope trick on the lifters. I always screw up exhaust leaks with lifters and that makes it very obvious. Every 4.0 you buy you should do a head gasket regardless of what anyone says or what it looks like. I paid $2500 for a somewhat running and driving 95 zero rust flat top. So that might help out with what you define overpaid. I love these trucks and they don't love me back. Reminds me of my first girlfriend.
I'm convinced the "concerning" sounds and sensations Land Rovers of the period make and provide are intentional design features at this point. You can either accept you own and rely on the mechanical equivalent of a horse as a means of transportation--and learn to appreciate the unique personality of each Rover--or go broke failing to make it the Toyota it was never intended to be. Hello, my name is Mike, I have the disease, and I'm terminal.
@@AddictedMotors I was stoked to find your channel! You make all the purchases I'm too timid too. Mad props for the amount of problem children you adopt. Your wife is saint :) I know that exact tapping sound too well. I've spent over 3k trying to diagnose it with Land Rover specialists who all have come back and told me to live it, least satisfactory answer ever when you have the money to sort it. Variously diagnosed as lifter tick, rod knock, exhaust leak, clogged oil passages. These are people with six figure tool sets and at least a decade of experience each. Adding Marvel Mystery Oil when it appears has kept my 4.2 purring; when the sound appears--I add MMO--its gone in 20 miles. 240k on my Classic daily driver and compression is still great as of testing 4 months ago. Worth a try if rebuilding this engine isn't in your plans. I hope something as simple as that sorts the Disco out. Cheers.
97s are slightly weird in that Land Rover changed emissions systems mid year. You can buy 97 disco parts that are completely wrong depending on pre-AELS and AELS status. This one is a later AELS vehicle. People will routinely put wrong parts on and wonder why it runs shitty. It affects a surprising number of pieces parts.
