Just picked up a 2005 XB this weekend. Tried to buy 2 others and they both sold before I could get to them. This one I drove 4 hours one way to get. It's definitely not perfect but it runs great and the interior is really nice. I already preplaced some crap tires and ordered some rear shocks since one is leaking. The previous owner put an aftermarket intake in it so I'm not sure if I want to change that out yet. I'm sure I will be modifying a bunch of things. It's been a while since I have been in the customizing game. My current daily isn't very customizable.
Anywho my name is Mike and I'm from Savannah Georgia. I hope to learn a bunch from this forum.

Welcome to the site, Mike. Good to see another East coast xB. You will see a lot of inspiration for xB mods here. Your ride looks to be a clean canvas for whatever you choose to do. Glad you realized a long time interest in the xB. Frank

When you pull the intake valves, measure to see if they are longer than standard specifications, if so, the combustion chamber temperature was probably too hot. If the other cylinder's valves are in good condition, maybe the intake manifold has a vacuum leak on the number two cylinder. Need to confirm correct ECU operation, proper ignition timing, valve and valve seat angles for tuliping, other vacuum leaks, EGR system, fuel/air mixture.

What ever it turns out, I hope it is not too expensive.

I initially planned to replace the engine.

The car had 289,000 miles on it, but was otherwise in quite good shape.

I decided to take it a step at a time.

Maybe I could just FIX it, save some money and learn about the car.

Worst case, I take the engine apart and conclude I need to replace the whole thing.


Upon disassembly, I was surprised with the condition, No signs of over heating or excess/unusual ware.

The Exhaust valves all looked well used up, on the valve faces, but the stems were in great shape,

to grind them would have reduced the margin too much.

All the cylinder walls looked consistent and as well as could be.

I decided to gamble on the fix.

I replaced all the exhaust valves and had the seats and intake valves ground.

I have about $300 in the "fix"

I'm quite happy with the way it runs.

The question is: how well will it work out as a daily driver.

Will it use oil excessively?

Will it nickle and dime me to death?

A. I have about $300 in the "fix".
B. Will it use oil excessively?
C. Will it nickle and dime me to death?
A. Super impressive win!
B. If you did not have the head milled, the compression ratio should not increase, and no change in oil consumption.
C. Only if you start modding; then it never ends. 😎

I did not surface or mill the head, it was Bitchen as it was.

It looked so good, I was tempted to reuse the head gasket! But didn't...

Having not even ridden in an xB, let alone driven one, the whole xB experience is new.

I have concluded the xB is a GREAT in town car!

On the FWY, not the best.

My car is quite Buzzy at higher RPMs.

And it tends to viberate at idle, in gear.

I'm suspicious of bad motor/trans mounts.

After installing a new battery, I hope to put on some miles and see how it goes, before more work on the car.

I DO plan to keep it as stock as I can, more or less.

I have been using the xB as a daily driver since the end of March.

At 1600 miles, last Saturday, the Alternator started acting up.

Today the Alt quit quite close to home, so I took it apart.


I was debating the replace or FIX choice.

The cheapest local rebuilt part was about $120 + exchange.

I found a small Electrical shop that had new Brushes for $10.

I bought the brushes without even taking the Alt apart,

I didn't have time to take it apart before I needed to run some errands.


Replacing the brushes was WAY easier than I expected!

The biggest part of the job was snaking the Alt off the car.

I just pulled off the rear cover and there the warn-out bushes were.

Two screws later, New brushes installed!

Alternator Fixed.


The Xb has been working well.

I still think some new motor mounts would do a better job keeping engine

vibrations out of the First cabin.

I can see the rear and left mounts and they look intact.

I can't see much of the right mount, so it is suspect.


oil consumption is noticeable at maybe 1/3 of a qt per 1000 miles.


Gas mileage has been 32-34 in mixed driving.


The xB is doing It's job quite well!!

update:

I have 3000 miles on THE Xb.

I added a Qt of oil at 2100 miles.

My over sized tires run the odometer 6% slow.

My corrected MPG has been consistent at 33, average.


I changed the right motor mount.

see: engine mount replacement


I NEED to get used to the lack of GO when I step on the gas.

I normally drive the xB quite casually but the other day I made a left turn

and almost didn't get out of the way from on coming traffic!

I'm NOT going to do THAT again!

If it were not for the main reason for the car (good mileage), I would HAVE TO

do some performance Mods...

unless it is your casual no freeway no rush hour surface street daily driver for work.....35mpg and 9 gallon fillup once a month.....it has it's place and is strong in that niche. We have 3 other choices for different driving or hauling or towing needs. xB would not be enjoyable in freeway autobahn duty......without another gear.

I'm coming up on 6000 miles.

At about 4500 miles, I got the dreaded Check Engine light.

The code was the Extra dreaded P0420, Weak CAT function.

I reset it and then it came on intermittently randomly,

anywhere from a few miles to a max of 630 miles.

I finally got around to giving it the low buck Fix, about 500 miles ago.

We'll see if the "Fix" takes.

I'm now at 10,000 miles and things are not looking good.

The check engine light (with P0420 code) now comes on just about every time I drive.

AND oil consumption has changed, along with other factors.

When I first started driving the 'box, I changed the oil and proceeded to drive 1800 miles before adding any oil.

After recently changing the oil, I ONLY got 800 miles in before I needed to add oil...

Two things have changed.

1) When I first started driving it, I drove it a bit like an old lady, who was in no rush.

.....I didn't exceed 65 and my goal was the best MPG.

.....Now I drive it like most others on the road, I keep up with traffic at 70-80...

.....I PAY the price in MPG, down from 33 to 30...

2) I changed oil type. The first oil change was Walmart's (the Dark Side) cheapest conventional oil 5W-30.

....Now, Walmart no longer caries conventional oil, so I am/was forced to use synthetic.

....I put in "10,000 mile Full synthetic 5W-30"

I was hoping the oil change would change the check engine light coming on, and it has.

It now comes on SOONER...


So at the least, I want to try a different oil, but which one?


On a side note, a neighbor has an RS 1.0 that has a problem with the engine and I MAY buy it....
