Today I had a friend helping me, we could only start and stop the engine because it would rev up to red line immediately on start up. We could hear a vacuum leak at the back of the engine.
Could a leak in a vacuum line cause it to rev up to the max?
We both looked at the exhaust manifold and intake manifold and it appears to be seated properly. The Fuel injectors and properly seated and no leaks.
Could it be just a vacuum leak.
The line that goes from the valve cover to the intake manifold has a crack in the cover where it attaches to the manifold.
RSWiser
Any line attached to manifold should be crack-free.
Since you hear leak at rear of engine, I'm not sure what else it could be other than intake, the MAP sensor is mounted on firewall but should be obvious if there is an issue, have a look at its vacuum line anyway.
When I installed my intake it was on the pins, when I tightened the first bolt it angled the manifold unevenly causing it to bind on pins. It was not noticeable and tightening the remaining bolts did not correct the alignment. I figured this out after disassembling again.
Are you using a new gasket?

Track-Lock Rear-end
I have a 1999 I just bought and am going to change the differential fluid. Book says to add friction modifier if it is a Track-Lock differential. How do I know without pulling off the access cover and seeing actual clutches? Just trying to prevent an extra trip to the parts store.

That said - just buy a gear oil that already has the additive in it. It says on the bottle. A lot of synthetics come with it already.

When Turning right like into a driveway it makes a rubbing/grinding type noise. shop had jeep in for 4 weeks and can not figure it out. they said everything seems to check ok and tight. anyone have any ideas that would help. Thanks for all input. Oh yea I am mechanically dumb so I have no clue what so ever.

Is there anywhere in this corner that a small coolant leak could be hiding? The main hose looks ok and the radiator looks almost brand new except the bottom edge.
I'm guessing radiator but really don't want to have to replace it already...

hey guys tonight i got into my xj after work and noticed my passenger side blinker was blinking really fast in the front and back and on the gauge cluster. All day its been ok and has never given me this problem before. Would it be just a bad bulb or relay or fuse since its happening in front and rear?
