A little more fettling this evening. When I topped up the oil the other day, I
managed to overfill it. The oil level seems to drop a bit more than I've noticed
before, when the car has stood. So I over-compensated when I topped it up which
left a bit less breathing space in the top of the oil tank when running, than is
ideal. So I simply removed the sump plug for a while to drain some oil out, then
could run the engine and pour it back in the tank to get the level correct.
Another little job I did was to re-fit the number plate lamp. I really dislike
that lamp unit, it's way huge and ugly, but until I can find a better alternative,
it does the job.

So I used the car a little more and got some miles under it's belt. All appears to
be in good order, so I was happy to have some time out of the garage for a while.
But I felt like killing an hour or so this evening, and decided to fit the forward
brace to the roll bar. I have tried fitting it a couple of times before, but it
needed some spacers to prevent the rose joints from flopping around in the brackets.
So this evening I made up the spacers from some ali tube I had, which just happened
to be the perfect size - much better now, though not much room for passengers any
more, never mind eh!

I've been suffering from a bout of apathy and a good cold, so I've been ruled of
doing... well anything really, for the last few days (although I did survive a
day helping Craig with
his car ready for SVA). However I had to resolve to look at the car again. It
had developed another oil leak, which didn't become apparent until it had stood
for a while. It looks like it is coming out of the seal between the mating
face of the side scavenge port and the sump. Disappointingly, the only way to
resolve this properly is to remove the sump yet again :-(
So this evening I drain the oil and remove the sump. As usual I run the car for
a couple of minutes to help the oil out, and again the oil seems to come out with
lots of tiny air bubbles throughout it. This is a little worrying, but I've no
idea what the cause is... I'll have to speak to some people to gauge opinion...

Onwards with the sump prep ready for re-fitting at the weekend. When I took the sump
fittings apart yesterday, I worked out that I think the oil leak was actually the oil
coming through where I've bolted through the sump wall to clamp the scavenge filter.
So how to fix this? I had fitted it with some silicone sealant in the hole, but
obviously that's a bit hit and miss. What I should have done in the first place was
to tap it at M5 then I could just use plenty of threadlock - but I didn't I drilled
at 5mm, hindsight is great isn't it.
So I decided the best way to do it now is to suck it up and tap it at M6. It's a bit
bigger than is ideal, or is necessary, but it should easiest to seal and should work.
I spent the evening doing the tapping and enlarging the holes in the other bits
which make up the overall fittings. Just need to get some bolts for the job tomorrow,
and I should be able to refit everything.

I had hoped to get the car running again by lunchtime today, but it didn't quite
pan out like that. In fact, it seemed to take most of the day to get it all done and
dusted, as I had bit more fiddling around to do to get the scavenge fittings fitted.
Still I got there, and then I ran the engine up for a while letting the oil show a bit
of temperature on the gauge. No leaks as yet, so switch off and leave it for a while,
still no leaks. So far, so good, we'll see how it fairs when it's been proper hot.

I didn't have time left to drive it out yesterday, but fortunately it's been a lovely
day here today, so a final quick check over and I dropped the car back down to the
floor. I went out for a good drive, I think I did about 50 miles. All still appears to
be oil tight, so I'll let it stand for a day and hopefully all will be well.
When I got back I thought I'd give the car a clean - not been done since last year!
Just a few bits to sort out before next weekend, fingers crossed for no more oil
escaping.

School report...
MAC Sprint Driving School, Curborough Sprint Course, 26th April 2005.
The weather forecast was ominous, the day started early and grey, but dry. I got myself
all packed up and headed off in the direction of Curborough Sprint Course, providing
some sort of entertainment for the black country rush hour traffic ("noice car mayte").
The first mistake of the day was when I stopped for petrol, and dozed off whilst
filling up, and put far too much petrol in it - d'oh, lesson number one...
I arrived at the track, parked up in my place in the paddock, and unpacked all the gumpf
from my car. A cursory glance under the bonnet and check the oil level, it'll probably
all be fine!
First thing is a briefing from the organisers and instructors, where we are talking
though some of the basic of sprinting, how it works, what equipment is required, etc.
We are also talked through the track and the ideal line. Our instructors for the day are
all experienced speed eventers and current top hillclimb championship runners.
With this out of the way, we take our cars down to the startline collecting area. We are
split into smaller groups and walk the course with one of the instructors, looking at the
line etc. For the morning session, we have cones placed at the corner apexes, which will
be removed for the afternoon runs. We will be getting four observed runs in the morning
and afternoon sessions, with feedback on each from three observers/instructors who are
bravely standing around the track.
Next is a group run around the track following the instructor (in a road car), which seemed
pretty pointless as they just took the opportunity to go too fast, which wouldn't really
give someone who hadn't driven the track before much of a chance to see what it looks like.
The weather has brightened up a bit for the runs, so away we go. My first run was really
just feeling my way in and getting used to the suggested line. Unfortunately no timing
today, so we don't really have much to compare our runs with, but the observers should
provide some useful feedback on lines. Second run felt a little better, though I don't
seem have the knack of getting it off the line... "you get quite a bit of wheelspin off
the line don't you" ;-)
Third and fourth runs go much better I think, and I'm starting to push it a bit more -
some nice controlled gentle tailslide out of the top hairpin, although on number four
I did have to get out of it a little bit as the grass/bank was coming at me a bit quick.
Back to the paddock now, and each of the instructors come over and go through the runs
with us. My feedback was generally not bad, although there was definite room for
improvement in the smoothness of my line.
After a lunch break, it was to be the same routine again, but the final run would be a
double-lapper - also the cones marking apexes were now gone. My fifth run was great, my
best run of the day. With the cones gone I think I was less focussed on meeting the exact
apex point, and so my line was instantly smoothed out.
Shortly after getting back to the start area, the rain started. It wasn't heavy, but enough
to dampen things down, so my next run was splendidly greasy, and I soon found I had
stunningly little grip off the line. Once on the move it wasn't so bad, but I was quite
tentative and definite short-shifting. We then had another round of feedback, which
confirmed what I thought about the first afternoon run, and that my first wet run wasn't
too bad. As this point it rained more heavily for a while, but there was a bit of a break
in the runs and I sat under my brolly in the car staying mostly dry. The rain eased for my
seventh run, but the track was more properly wet this time. It was actually easier to drive
wet than greasy damp, and I think I probably went just as quickly, but still not trying any
heroics.
Final run and the rain had stopped falling but it was still a bit wet. As I pulled up to the
line, the marshall said "don't do what he's just done, and forget to turn right", meaning it
was a double-lapper. Apart from being a bit heavy on the throttle out of Molehill and having
a look towards the grass, I had another good lap, probably my best wet lap... except I was
so concentrated I did do what he just did, and forgot it was a double-lapper!
I returned to the paddock somewhat annoyed with myself, but there was nothing I could do
about it now. Won't make that mistake again in a hurry.
So that was it. It was an interesting and enjoyable day. Shame about the rain in the
afternoon, as I think I would have been going quicker judging by my fifth run.
We were given a mark on three of our runs, and some random calculation turns the marks
from the observers into a %age. Top score was 82%, low score was 54%, I got 72%. We were
also given a couple of photos which had been taken of us during the morning runs, which
was nice.
It was a good day. Would I recommend it? Maybe if you were a total virgin to these things
and wanted to get into sprinting. Having driven Curborough before, it was great to get the
advice from the observers, but the number of cars (compared to a test day) meant a bit of a
lack of runs and extra hanging around between runs. I'd certainly like to get back there for
a test day to put it into practice a bit more...
