Serious question...

[USAFXJ]

All jokes aside, what kind of advice can you give someone who is new to the XJ family and very new to have a 4x4. I am always afraid I will f up the transfer case. I have been told that the 4.0 litre is damn near bulletproof if you know what your doing with it, well I want to learn everything about the 4.0 litre 4x4.

 

[SpartyKrunk]

There is not much to learn about the 4.0 It's very simple construction and simple to fix. They can take a beating, and function.

 

[USAFXJ]

What about improving MPGs, my daughter lives in GA, and I go visit her minimum twice a year, what can I do to improve the gas mileage?

 

[SpartyKrunk]

Keep it mantained. Clean plugs,your cat must be functional with the honeycomb unbroken. believe it or not the cat makes a big diff in mpg. exhaust leaks also create a drop in mpg.

 

[USAFXJ]

what about anything aftermarket for the engine? LIke high mileage oil, a different intake, etc?

 

[SpartyKrunk]

of course. that should be 2nd nature to everyone. warning, stay away from K&N filters.

 

[USAFXJ]

Was planning on it, what about AEM?

 

[SpartyKrunk]

I'd go with AEM. How hard do you wheel? Or how often are you on rural highway? Snorkels are more than just for going under water. They let your intake breathe fresh air from the side of the road than the grime thrown up from the vehicle in front of you.

 

[USAFXJ]

Well since I have only had the jeep less then a week, not alot. My dad and a large handful of my friends live on rural roads. I have thought about a snorkel because it does tend to flood alot where my dad lives.

 

[SpartyKrunk]

then a Safari snorkel would not be a bad investment. They are not that expensive and easy to install yourself. http://www.safarisnorkel.com/snorkel/ss1195hf/ss1195hf.htm

Wouldnt I have to cut through the fender though?

High capacity intercoolers keep your engine alot cooler equaling out to saving fuel. http://www.safarisnorkel.com/turbo/hdj100/sc1hdfte.htm

Drill holes and such, yes. But once you get a snorkel, you will never go back. You get a highly detailed sheet of paper charted with drill locations. You just tape it to your left fender and get going.

NEVER use 4-wheel drive on paved roads.
Keep out of deep water unless the XJ has had vent lines moved up higher.

 

[SpartyKrunk]

yep.

I would definitely need some help so I dont f it up

 

[SpartyKrunk]

it's *uck up proof really. They basically put a picture in the fender of your XJ and tell you where to drill. After that, they're all simple connect A with B pipes. Worst comes to it, i'll go do it for you.

 

[USAFXJ]

small drill holes, or holes larger then an inch or two?

 

[SpartyKrunk]

one large hole for the snorkel itself, four small drill holes. lookee here:
