Considering the leaks when it rains, I was expecting a horror show of rust underneath. Not bad for a Jeep that's spent its entire life in snow and next to the ocean. Anyone have a recommendation for a new gasket—or should I just refresh the old one with some silicone? Not planning on folding it...
I have a similar problem. My speedometer is constantly about 3mph off, no matter the speed. My speed according to an app plugged into the OBDII port is dead on with the GPS, but the speedometer is constantly off.
Just to be clear, your 2000 came from the factory with a non-TUPY 0331 head. That is what you have, unless a previous owner replaced it with a 2002+ head, which are also 0331 heads but are labeled TUPY to signify the casting defect that caused the cracking was fixed. I can't imagine that is the...
It's luck of the draw. I have a 2000 TJ with the original 0331 head and it's fine so far at 120k. I have a 99 WJ with a 0331 head with 165,000 miles and it, too, is fine. Will those heads crack? Maybe, maybe not.
You almost certainly have a cracked head. Your 2000 model year is susceptible to cracking between cylinders 3 and 4. Your only option is to buy a remanufactured TUPY head or a new head from a reputable company like Clearwater...
Before you spend all that money, know that the NV3550 in your TJ is notorious for making a rattling sound in neutral when your foot is off the clutch. It sounds like marbles rolling around a can. It's completely normal and is just the input shaft spinning the gears, which is very audible due to...
Oil thins as the engine warms up, so the pressure decreases. Per the operator's manual, as long as your hot idle is greater than 13 psi (or a little less than 1 bar), then you're fine. Don't overthink it.
Wow, great job. So it sounds like wrist pins are the answer? I wonder what happens if they are never replaced? My old XJ basically made that noise from 50,000 until 250,000 miles, when I junked it because of rust. Anyway, well done.
If you drove it 700 miles, you should be OK. Modern oil is incredibly good at maintaining lubrication with contamination. I've heard of people driving a bad 0331 head for a few thousand miles before replacing and it ended up OK. (Not recommended, obviously.) Go ahead and replace the head. Get a...
Is it worth $800? Sure. You can part it out and easily double your money. But you don't want to part it out. You want a project.
How much is your time worth? Because that is going to be a very, very big project. You need full-length Safe T Caps at a minimum. That's $900+. (You can get Pocono...
