Engine work on XF 4.1EFI
Milan
It has been my parents since new and now that I have it I would like to do a
few repairs.
From what I have seen, the engine is definately down on power, and uses too
much petrol, but doesn't blow any smoke (always a good thing =)
So I am going to change the head gasket (oil leaking from rear of engine,
and losing water), and either clean or replace the injectors.
The car has always been regularly serviced, but is there anything else I
should look for while I have the top half of the engine off?
Any help much appreciated.
Milan.

the heads off, its probably worth having the head recond too,
definetly machined, maybe the valve guide seals - just because its
cheap insurance and the valves/guides can be looked at at the same
time, get it acid bathed as well.

Doesn't seem to be rattly, although its hard to tell sometimes because the
idle is all over the place. Probably due to the blown head gasket =) I'll
have a better listen for it now that you mention it.

approx. $250. If the lifters are worn you can bet the cam is the same.
This also gives you the option to slide in a slightly warmer cam

No problems Squirt, this is of course true

Did you price dropping a MPEFI 4.0 motor in it? you can pick up a used
one for around $1,600 with low k's, 157kw's is probably more than you
will get from a EFI 4.1 for that sort of money.

4.0L MPEFI engine into an XF?
I've lost the link to that site that has all the Ford engine power figure's.
Can anyone give me a rough idea on the power figure difference between the
4.0L MPEFI and the 4.1 EFI from the XF?
Thanks.

Try and get a peak under the bonnet of an XG ute/van and compare it
with your setup. as yours is already MPEFI it shouldn't be that hard
as you will already have a hi pressure fuel pump, mountings for the
EEC computer etc, the motro will bolt up to you 3spd auto and iirc it
used the same engine mounts, if your wanting a decent power upgrade,
i'd seriously look into it further, you can pick up a low K 4.0 for
around $1,600, get the engine wiring harness/EECIV, air box, exhaust
manifold.
Try and get hold of a XG ute/van workshop manula (try the libraries)
preferably a proper Ford one, then get an XF one and compare what has
to be changed, should be a reasonably easy job and cost no more tha
$2,500 all up and you would have a ball tearer of a car :-)

MPEFI 4.0 is 157kw's
4.1 EFI was 120kw's iirc

The XG ute workshop manual is a supplement on the XF manual. You'll need an
XF one anyway for anything but the engine, transmission and a few odds and
ends.
The XG motor put out 148kW, not 157, but I think the XH was up to 152.

Mine's actually a 4-speed manual. No reason why that shouldn't bolt up to a
4.0?
Also, the exhaust was fully replaced towards the end of last year (same
diameter as original), so I'd gather that extractors could be an option if I
had to find an exhaust manifold anyways?
> $2,500 all up and you would have a ball tearer of a car :-)
I'd say that would be a resonable price to pay since fixing the existing 4.1
would probably cost at least half that anyways :)
Milan.
Milan
That would be a healthy improvement, seeing as I doubt the XF is making its
120kW's anymore :)
What about comparisons torque wise? I seem to remember the XF used to have a
fair amount in her...that was a while ago now :)

This is true, but I was referring to the motor in the EF onwards :-)

My mistake, for some reason I was thinking you had a Fairmont Ghia. I
wouldn't think it would be a problem, its really only the
bellhousing/input shaft that would be of concern, the 4spd iirc is the
BW single rail, the 5spd is a BW T5 which I believe is based on the
single rail?

Extractors would be the go if you wan't to spend a few extra $$'s, or
cheaper, just get an exhaust place to bend you a new engine pipe.

A stock reco 4.1 would cost about $1200 + about $250 R/R so for
roughly an extra grand your going to get a 2nd hand 4.0 (which if in
good cond will probably last as long as the reco 4.1 anyway) with a
good dose of grunt in a comparativly light XF, certainly an easy mid
15's contender and importantly no 6 pot Commodore (including the VL
turbo) will touch you, thats assuming you've got good tyres/traction
of course :-)
Next you'll want an LSD as you'll get savage wheelspin :-)

they have O/Head cam
which makes them longer than the 4.1.
Milan the $2500 I spent on my engine was well worth it I've gained approx. 50 kms
extra per 80 lt. tank
and heaps more power but most of all its really responsive.
I rebuilt the engine myself which saved a bit. This is what the $2500 paid for
Block acid dipped, all surfaces machined, rebored 20thou over size
Full reco head inc. 2 new valves
Crank ground and balanced (ground 10 thou)
New stage 2 cam, Dynotec is the brand (imported by Crow Cams)
Full gasket kit including welsh plugs and EFI gaskets.
New big end, main and cam bearings.
New crome-moly rings (only good if your going to run it on petrol)
New pistons, The pistons that I used are the same dish as an XD x-flow 22.5 cc
dish, the XF are approx. 26.5 cc.
I wanted to put flat top pistons in it but was strongly recommended to use dished
pistons because flat tops
would up the compression ratio to approx. 15/1 (way to high) this would destroy
the engine.
New water pump, engine mounts, thermostat etc. etc.
I also spent $250 on the gearbox putting 5th gear in it. I put the gearbox in 12
months ago
If you want to do the same instead of buying a 5 speed look for 4 speed with the
serial No.
Borg Warner 0507-XXXX.as lots of people don't know that the 0507 series is a 5
speed box with 4 gears in it.
Fifth gear is in the extension housing not inside the gearbox itself.
Also the other thing people don't know is that Ford retarded the cam 4deg to meet
anti-polusion requirements.
Hope this helps.

Thanks Squirt,
Ok one thing, I'm no expert here but don't the XG utes have the 4.0L? The
space under the bonnet would be the same as the XF wouldn't it?

IIRC, the car already has an LSD, I have been told it came with one when

They certainly do fit Squirt, the XG ute/van has them :-)

I did virtually the same as above to my Mustangs 302 Windsor, but also
included a new oil pump, lifters and double row roller timing chain,
got out of it for $1470 all up including hire of engine crane, oil,
oil filter, new bolts for water pump etc :-)
I sold the 'Stang last year after about 15,000k's on the new donk, the
guy checked the compression and it gave 220psi on 7 cylinders and 215
on the other, I was pretty pleased ith my efforts :-)

Thats a great tip squirt.

Is this after shorting the computer?, if you don't you will be 10
degrees out in your timing and loose power.

I think your right actually as its an S pack, still you'll get savage
wheelspin from 2 tyres :-)

Yep, theres two different gearbox's, the T5 and the 0506/7 series BW 5
speed, the T5 is MUCH better and stronger.

need to get my hands on a proper Workshop manual before I get involved with
changing anything.
Where would I be able to get one of these? I have heard the local library
might be a good start. Any other places?

Is the diff strong enough to cope with the extra power? I seem to recall
that the original one had to be replaced about 5-6 years ago, I'm not sure
what caused it to break though....

Should be as i think it's basically the same LSD they put behind the later
model falcons anyway.

A car parts shop, i'd be using the libraries to dig somwthing up first
though, you could also try getting friendly with a Ford dealer service
dept, they might let you see the micro fiche or watever they use now
of the XG's bits etc
