Writing this time not about my own XJ8, Harlem, but a friend of mine’s.
My friend recently bought a non-running '98 XJ8 and is letting it sit it out for awhile. I checked title for her recently and it looks like the PO didn’t re-register the car for about the past 10 years, so presumably she had been sitting (non-running?) all that time, as well. My friend did have a tech take a look at it at her home to see if he could figure out why she doesn’t run, and he was of the opinion it had something to do with the fuel tank (or maybe the fuel pump inside?), per her. Basically r/ring the fuel tank should get her running again, he opined.
If I had known my friend was going to buy an XJ8 ahead of time, I would have warned her NOT to buy a pre-00 MY, due to the Nikasil sleeve liner issue. Anyway, what’s done is done. I was wondering if there is any way to find out whether the Nikasil recall/update was done on this particular car, w/o removing the cylinder head. Did Jag keep a log of XJ8s that were brought in for the upgrade, based on VIN #? If so, we’re in business (unless it has a different engine in it than the original, of course).
If not, I got to thinking … could a person use a LizardCam fiber-optic setup to go down one of the spark plug holes and take a look around inside that cylinder to see if the upgrade has been done? If so, how would the appearance of the Nikasil liners look, and would would the difference be visually if it had the upgrade done to the other type of metal alloy?
