PLEASE HELP, I PURCHASED MY FIRST TVR ON SATURDAY, A 96 4.2 WITH 24K ON THE CLOCK. DROVE IT BACK THE 170 MILES TO BIRMINGHAM, NO PROBLEMS. SUNDAY ARRIVES, AND ON A SMALL JOURNEY TO THE LOCAL SHOPS, ALL HELL BREAKS LOOSE. MIL LIGHT FLASHING INTERMITTENTLY, OIL PRESSURE GOES TO ZERO & WHAT SOUNDS LIKE AIR ESCAPING FROM THE BRAKES, AS THEY ALSO STARTED CLICKING UPON APPLICATION.
NOW I HAD BEEN TOLD TO BUDGET 3K A YEAR ON REPAIRS, BUT I WAS RATHER HOPING IT WOULDNT ALL BE ON DAY 2.

Dont drive it anywhere. MIL alone is not normally a problem when on its own (ie can be down to a load of different fuelling and mxiture issues etc and the worst that normally happens is that the cats get fried). If you dont have cats then that is less of a problem obviously.
Zero oil pressure can be a problem obviously! This can be misleading though as the pressure spring can let go and give false readings. I assume that the oil light is on as well.
Get it to an AJP expert on the back of a low loader asap.

I feel for you.
Had the same scare with mine, but as I drove it home.
I have to ask, was it a private purchase or via garage?
If it was a garage, get them to deal with it, or you
may regret it later in the wallet department as I did.
It could all be something minor.
The oil pressure throws a wobbly when the fuel starts
to vaporise and on the older cars, this seems to happen
quite a bit.
Did you stop the engine when the pressure dropped,
were you driving fast or just idling along, as this
might give a clue?
This problem could also see action on the MIL light.
Have a read of this thread and see if it rings any bells?

As gazzab rightly said, don't drive it though until
you have had it checked out. It may cost very little
and may be a minor hiccup.
Good luck!

Yep
when mine has cut out before, the oil pressure drops and the car stalls. Only happens when the car is real hot and stuck in traffic.
Have you tried to start it since. If it's fuel vaporisation then when the car cools down it should start ok and read ok for the oil pressure. If it still doesn't read ok then could be something dramatic or as simple as the spring on the pressure relief? gone which should be a minor fix.
Since mine got serviced it was running great and keeping about 25psi even when real hot. It has had work done recently which involved battery disconnected and it hasn't been quite the same since, almost cutting out a couple of times.
The brakes are probably nothing. The click a bit when the pads are a little loose and joolz put some sticky stuff? on the back of mine to stop that.
There's a place in birmingham, tvr mads, the servicing part is a different name i think. they seem like a friendly bunch and will probably give some advice over the phone to at least let you know the possibilities. Alternatively phone joolz and see if he can squeeze you in.

If the pressure spring thing goes then the zero pressure is not a false reading... it is pretty accurate! Without that spring, there is no oil pressure.
Agree that recovery is the best way forward.

OK what I meant was that a damaged spring isnt an engine problem it is a damaged spring only.

I PURCHASED IT PRIVATELY, ITS OIL PRESSURE IS 60PS AT IDLE & 80PS WHEN RUNNING. IF I GO & START IT NOW IT WILL BE 60PS, THEN AFTER A FEW MINUTES IT WILL GO TO ZERO UNTIL I REV IT & THE OIL PRESSURE COMES BACK. ON ONE OCCASION IT STARTED WITH 5000 REVS (WITH OUT TOUCHING THE ACCELERATOR) I THINK IT MAY BE THE ECU. I'M DROPPING IN TO MY LOCAL TVR CENTRE TONIGHT & THEY WILL RUN A DIAGNOSTICS CHECK ON IT. I'LL LET YOU KNOW HOW I GET ON.

Gazza,
I think what graha meant is that the oil pressure readings sound normal (until it starts playing up of course).
The flashing MIL light can be a nmber of things, one of the likely ones being a faulty lambda sensor. Sounds as though it is linked with the other faults (high idle, cutting out).
Get it to a dealer, they can read the fault codes from the ECU so we don't all have to keep guessing
Rob.

Its back, many thanks to mike @ www.HORIZONMOTORSPORT.CO.UK my local independant.
He diagnosed the fault as a faulty spring from the oil pressure relief valve (release valve ?)
We managed to get the modified spring late yesterday & knowing i was desperate to have another drive, he kindly fitted it at 7PM last night, sorry !
I found the car in last months sprint, P666TVR, i'd be interested to know if anybody else had been to see it.
I intend driving around aimlessly today, could this be my first ever sober England game ?
