Date / mileage Event Solution
1st Year
1999

3/20/99 first start --
3/26/99      130 #1 intake valve stuck in it's guide recondition and upgrade head to XF1700 spec
4/20/99      130 first (re)start --
4/21/99      200 15..20ftlbs of torque needed at the hubnut to turn either driveshaft (gear in neutral, brake pads out) differential needs break-in. This goes eventually down to 1ftlbs at about 5k miles.
5/26/99      700 rear A-arm crunch noise add washers at chassis mounts, relaxes tension on the A-frame
6/3/99      1600 transmission vibration/noise I forgot to put in the pilot bearing - engine / xmission out - insert $9 bearing
6/20/99     2302 odometer broken --
6/29/99     2xxx?? speedometer broken  get replacement (warranty)
7/20/99     2xxx?? distributor cap spring lost drilled the cap and put in a pianowire loop, tied at the base of the distributor with a ty-wrap (still ok after 30k miles)

8/5/99      5xxx?? new speedo broken again get 2nd replacement (warranty)
checked cable length to make sure it is not too long - seems ok. Bad batch of speedo's.
8/6/99      5xxx?? Blinker relay stops working open it up and clean contacts. Black dust inside.
9/1/99      7000 decide that 110BHP is not enough power upgrade the XF1600 to XF1700 with a Kent 244 cam this coming winter.....
9/30/99    7600 order pistons and 244 Kent cam from RMSCI and plan for the upgrade --
10/17/99  8000 car is getting too cold to drive around 30..35F order fresh air heater
10/20/99 8100 Radiator leak at  the top 1" blanking nut solder with silver solder
10/25/99  8500 Valeo voltage regulator goes out (on alternator) runs 20V board voltage...... very bright headlights... replaced bulbs.
redesign regulator (corrects  field winding bias issue, causes after runs when the fan is running at shutoff), mount under carbs to avoid baking by header #1
12/26/99 10100 dismantle engine - prep for XF1700 upgrade -- Hobbyist Wisconsin plates do not allow driving in January, also 0F/-18C weather makes driving less enjoyable
2nd Year
2000

2/4/00   10100 1st start as a 1700/244 cam noisy at startup, allow 500mi for break-in. Initial compression about 160psi, after break-in around 190psi (warm)
3/5/00   10900 Clutch cable breaks far from home - have to start in 1st gear, shifting w/o the clutch is not too bad otherwise.
Embarrassement at a couple of the intersections.
Get new cable and a 2nd as a spare in the boot
3/24/00  11400 Install engine mount restraint plates as a precaution --
4/2/00    11800 K&N airfilters self destruct replace (blow back from carbs is desolving the rubber seals. 10% alcohol in Wisconsin fuel does that)
4/5/00   12100 A carb stud loosens - leans out mix on #2 loctite and center punch studs behind the manifold
4/6/00   12150 Radiator leaks again at the top resolder again
5/5/00   13500 Radiator leaks at the bottom resolder and hope for the best
8/27/00  17000 driver side floor fails (10 rivets lost) drill out rivet remnants, re-drill and use 3/16" stainless rivets after epoxying floor to chassis
9/3/00   17600 Radiator leaks everywhere resolder everywhere
12/16/00  19000 put it away - too cold (25F is the cut-off), also too much salt --
3rd Year
2001

2/4/2001 19000 2001 driving season starts - still cold, have to drive around the salt :-) --
7/1/2001 23000 Junked the Heavy Duty Radiator, it's a sieve  get Alu radiator - much much better cooling and ... no more leaks... wow
10/30/2001 28000 thermo sender goes flaky replace
12/18/2001 30500 Parked for the season ... just can't stop driving......

 


Event/mileage Issue Solution
4rd Year. 2002 .
2/1/2002 30,500 I'm back - Wisconsin Hobbyist plates do not permit driving in January. Normally this is ok, but this year there is no winter.... .
4/21-30/2002 31,500 Swap in 2.0 Focus Zetec  .- see XF-Zetec conversion page
5/2/2002 32,000 Remapping of GEMS fueling map continues. Mileage now around 17mpg, but a lot more power Note: (5/03) - lean out cruising map - AF approx. 13.5 - gives 23mpg freeway, 20mpg country roads
5/30/2002 32,800 Running good, except odd event where revs limited to 4500rpm ..issue disappeared... ECU gremlin?
6/4/2002 32,900 (GEMS) ECU overheats - 3000rpm
see near the bottom of  XF conversion page
Added cooling.
Conditions:
95F weather, sidescreens in, heater valve not completely shut off. ECU mounted on the Exhaust side firewall inside the scuttle. ECU too hot to touch. Issue resolved with added ECU cooling installed.
10/25/2002 37,300 Clutch cable brakes again. Seems underrated. Too much force is required. Snaps off, 1/4" back from the eye in the footbox. replaced cable for now  - considering hydraulic. Craft something from Pegasus or Jegs parts.
12/19/2002 39,500 Weather perked up, so out I was, but speedometer failed again... replaced 1" flexible cable in right angle drive at the gearbox. Also shortened both ends of the main cable to make sure it runs free enough to spin the speedo by hand from the gearbox end of the cable.
12/20/2002 39,501 Battery failed - low temperature starts killed it off. Fully charged, but capacity is not enough to crank a 10.5 CR Zetec at -0C /<32F temps. New Johnson Control (aka Sears Diehard) sealed Gel battery ($45)  is perfect. Slightly lighter, fits about in the same space and 340CCA !  Need to device pole caps for general & track safety. 
12/22/2002 39,600
Parked for the season

5th Year
2003

2/1/2003 39,600 Back on the road
4/15/2003 40,100 installed adjustable  Leda shocks and new springs - however 275 / 200 lb/in   F/R is too stiff . Handling improved significantly, but since it's a daily driver, I 
ordered 220lb/in Front and 150lb/in Rear springs.
Running 275/150  F/R now.
8/23/2003 44,000
rattle inside the muffler, sounds like a weld had given away
lost 1 of 3  #4 exhaust header bolts, others loose. replace/retorque - fixed.
10/08/2003 46,200
deDion tube failure...whoOAaa
Left rear shock mount cracked, causing 1" left rear suspension drop.
weld up the old tube to close season, ordered new tube .....
But..we're back on the road within 2 days.
...I hope it's safe :-)
11/07/2003 47,100
Speedometer out again. 1" flex drive wire broken - this is fragile when it gets cold and the bowden cable stiffens. This is Wisconsin, it does get cold here..
use a 1" x 1/8" square brass rod section as a link between right angle box and gearbox - no more troubles. Also, no more wavy speedo needle.
11/25/2003 47,600
new deDion tube received. Looks reinforced. Also received hydraulic clutch actuation parts
Mounted - slight adjustments needed, for brake-T mount and Z-arm openings, otherwise fits fine
12/09/2003 47,800
Season ends - snow and salt are here.... it's hard to stop :-)
6th Year
2004
2/1/2004
Back on the road again of course !

5/1/2004   49,000
Starter solenoid keeps hanging up. This is still the old starter from the Crossflow. It's a Magneti Marelli.
lubricate solenoid plunger. Dry graphite works best. Also added heat shield wrap to the starter  / solenoid
7/6/2004  50,900
brake pads glazed (still about 30% left)
replace (original) brake pads
7/17/2004   51,500
Nothing to report.... just running great, except the weather has been lousy in Wisconsin, hence not many miles have accumulated this year.

July 3/'04 Black Hawk
Farms track day...

kinda washed out....

12/31/2004  53,000
The car has been very solid this year, but driving has been curtailed by THE worst weather we've seen here in Wisconsin in a while, with perpetual downpours. Some rain is no problem, but there are limits :-)

Fortunately the 2004 driving season ended with a perfect 45 degree F - blue sky day - I suppose global warming has even reached Wisconsin

7th Year
2005
March 53,000
Back on the road!

May 55,000
Just running good, but... the weather has not cooperated. Cold is ok, but rain is not great.
Brake light switch is out again... need to really fix this..
September 58,000
Rear brakes glazed
new rotors, new pads
11/30/2005  59,000
Season closed... winter is early this year




8th Year
2006
February 59,000
One 30mile spin - 35F, but that's enough!

3/12/2006 
Last spin with the old gearbox - time to change!
3.36 1st / 1.81 2nd gear a 3.92 diff and a 2.0ltr Zetec does not work well. Last year October visited Brian Hill and his team at BGH Geartech. He put together an E7 kit for me, which I'm about to put in.
Original ratios: 1st - 5th  3.36 / 1.81 / 1.26 / 1.00 / .82
New ratios: 1st - 5th  2.75 / 1.75 / 1.21 / 1.00 / 0.85
3/29/2006
Not much spare time, but, the box is done - time to put it back in the car
See Gearbox upgrade
page for details
4/1/2006  59,250
1st run with the uprated box
sofar so good. Better put some miles on it...
I just noticed that the old T9 boxes actually used trust washers on the layshaft... hmm.. maybe I improved it :-)
5/20/2006 60,000
Front rotors worn
New rotors and pads.
5/22/2006 60,400 Lotus trackday at BHF - Gearbox worked great!  No more 3rd gear crunch. The dreaded front wheel lift-off due to the 3.36 gear has finally been put to rest. Last year with 3.36 and the sticky racing slicks, the car did a mini-wheely on leaving the pitlane and I almost hit the exit wall...
We now have clean starts with these new ratio's.
6/2/2006  61,000
coolant in the driver side footwell - heater hose split
replaced
7/30/2006  63,000
ECU overheating again after coming of the freeway in 100F weather.
Added noise filter to 5V regulator, increased cooling fan capacity - seems to work
9/1/2006  63,500
Throttle cable frayed... hanging up in the sleeve
Replaced it with the old throttle cable I still had laying around from the Crossflow days.
10/15/2006  64,500
GEMS ECU fails - replaced with DTA S60
DTA S60 PRO is DTA's latest development
This DTA is an excellent unit. Features, programmability, monitoring is quite a step up. Great logging features!
Combined with a WB02 (Bosch NTK) gives much closer tuning than the GEMS.
12/1/2006, 65,000
Season ends... it's very cold here (10F)

12/12/2006
NOT!
Back in the car!  It's 35F and dry, some rain washed much of the salt away.
12/31/2006 65,500
50F!!!.... yes, this is Wisconsin, not Florida
(normally it's 10..20F this time of year)
Winter has arrived.
12/31/2006 65,500
Left rear lower shock mount (1/2") bolt sheared
Issue caused by trapping a small section of bushing rubber under the washer, preventing establishment of proper bolt tension, leaving it to bend and fatigue. Used larger plated washers this time and ensured proper seating.
Replaced all lower suspension bolts with plated Grade 8.

9th Year
2007
1/3/2007 65,500
Left lower A arm balljoint needs replacement.
Locknut loosened itself ....  Retightened for now, but need replacements. Not bad for 65k miles.
new ones ordered - will install these when it gets warm(er)
1/5/2007 65,510
Left lower rear shockmount bolt shears off.
Had to get tools from home (10mi's) and do roadside repair.

Replaced all lower suspension bolts with Grade 8 plated.
Suspect this failure was due to trapping some piece of bushing rubber under the bolt washer, preventing proper bolt tension to establish, causing significant bending stress.
1/26/2007 65,550
Using full sequential injection mode causes cam sensor errors below 1200rpm, i.e. idling >5 secs stalls the engine.
Replacing Ford's magnetic cam sensor with a Honeywell Halleffect device. The DTA S60 ECU has both magnetic and Hall effect inputs. The Honeywell-IGT101DC does not quite fit, thus a bushing is needed to fill the gap as well as an O-ring to seal it off. Bushing: L = .5", ID = .705", OD = 1.01"
Zero cam errors now!  Solid idle, smooth shifts.
5/31/2007, 67,000
Throttle cable is not fully returning
Replaced with 1/16" heavy duty mountain bike brake cable.
5/31/2007, 67,000
Overheating when sitting still in traffic jams in 90F weather
Replaced cooling fan thermoswitch (in filler neck) with a 75C model (was 92C) - works perfect even in super hot 90F  (32C) weather with traffic.
7/22/2007, 69,500
Front wheel balance issues. Haven't had this in a while. Proper centering of the rims is important as I've noticed that with hasty wheel mounting (track days) the rims may not be perfectly centered possibly.
Last session had 22 (!) stick-on pieces of lead on one of the wheels..
Back to traditional transverse and radial balancing solved the issue. Just 2 small rim weights / wheel. Wow.. now it's good.
Oh.. that's $12/wheel.
10/16/2007, 71,700 Speedo out ...again. - check this eve, probably the cable at the right angle drive fell off... the Oct 8 track day was great, but new Avon's did vibrate slightly, causing things to come loose.
The right angle drive had vibrated loose.. no big deal. The high speed running at Road America probably did that. Car still vibrates >100mph and power is off > 120mph, due to having "lost" the ECU map after the TB issue... to be corrected over the off-season months.
11/22/2007,  72,100
Ok, season end is here. Snow came last night and a lot of salt.  That's it then. It's early this year, but given the length of the "to-do-list", it may well be a good thing, as I still can't stop driving this car...

10th Year
2008

3/11/2008, 72,100
First drive in 2008!  At last. It's now a balmy 33F, almost +1C, here in Wisconsin. Still sheets of ice and snow, but no salt!!  Salt ran out in January having received a record 90" of snow fall.
Car needs tuning, the TB's aren't properly tracking since last year, drawing false air on idle...  I'll work on it, but I need to get some driving in first :-)
