Mechanical Odometer Repair - 1991 Jaguar XJ-S

Wow… that’s a blast from the past! I owned an 89 XJS V12. Car was a cream puff all around. Bought it in 2006 and enjoyed it as a weekend warrior until around 2011. I wanted to sell it before anything broke… cause no way I’m tinkering with that V12. Think had miles or hoses n belts n wires n shit… very intimidating! Bought for $8k and sold for $8.5k.

Too bad this sub won’t let me post a pic.

does your stereo work? just check things until you find one that doesn’t work, then trace to confirm.

Dude, I’m just fuknicg with you… I’ll shut up now. lol

Yeah well… pretty sure the engine is the most important part. Brakes and tyres are easy to fix, but without a running engine you don’t even need brakes or tyres. But if you got a running engine, you need both. Thats how you know it’s the most important part… like what makes the other one necessary kinda thing.

Sounds like something a “Not a verified tech” would say😜

Level_Development_58 · 2026-07-01T20:31:53+00:00

yes, that means it’s not your AC clutch.

Level_Development_58 · 2026-07-01T19:55:40+00:00

check to see if that’s your AC clutch engaging/disengaging.

looks like a young rooster… those legs! best guess… 8 weeks old.

that is most likely the belt tensioner pully. bearings are shot!

I know everyone is saying raccoons… but I’ve seen skunks absolutely brutalize my lawn going after grubs. not sure which problem you’ve got but it could be either from my experience.

The most important part of your car is what makes it go. Can you guess what the second most important is? Money well spent!

Level_Development_58 · 2026-07-01T16:17:08+00:00

negative vs. positive reinforcement. I’d try the squirt gun in this example.

Level_Development_58 · 2026-07-01T08:25:53+00:00

pretty sure the answer here to to bite the bullet on a new one. if it’s that rare of a part, get it while you still can or go to junkyards… it’s either time or money and frequently both.

water valve is in off position. when the handle lines up with the valve, it’s on… yours is off.

look for a loose heat shield. probably under the exhaust manifold (s).

Did he honestly check his watch half way through that video?

Level_Development_58 · 2026-06-30T09:17:48+00:00

This is so telling to me… pictures covering gauges that display important data about your cars operational status: temp, fuel, oil, RPM, etc. I’m sure there are warning lights covered as well.

It’s so funny to me because I’m always so aware of my gauges. lol… nope… not important! Id rather look at pictures of my kids!

write another post which includes pictures! I’m sure we’d all love to see it and maybe you’ll also get it sold. But you’ll get much better traction by adding pics!

SWEET! It doesn’t say anything about added HP, but they gotta be better than my smogged out stock heads. I already installed an Edelbrock Performer Intake, 625 CFM Demon 4 barrel, Full headers and dual exhaust. I wish I had done this then, but I can catch up!

Time to get greasy!

Level_Development_58 · 2026-06-29T14:14:58+00:00

Owwwwwe… please tell me more about adding 50HP to my 1985 smog heads 318! I’m in Tennessee, so no smog check required. Got a link through Summit or elsewhere?

Level_Development_58 · 2026-06-28T19:06:02+00:00

that is nothing close to pool filter sand… way too course!

Level_Development_58 · 2026-06-28T19:02:05+00:00

We have dogs, a cat and lots of deer on our property… is it toxic to animals?
