Weird thing happened today.

I went out for a run in my cerbera - 3 hours around the Cotswolds and she didn't miss a beat.

Back into cheltenham and following the traffic through town the temp rises slowly until its at approx 90-95' on the gauge.

Sat in a queue of traffic idling and starts to run rough, oil pressure starts to falter and then fall. Oh no thinks I.. Then it cuts out.

I restart on the button and it is ok, oil pressure back up to 60-70psi, drives the remaining 500m to home.

Any known issues? Easy things to change 'preventatively'?

Car is a 97 4.2 ajp

Oil pressure will drop off at hot idle, mine goes down to 35psi when its hot and standing, 80 psi cold starting.

Wont fuel vapourising affect starting hot, it did with me until i wrapped the fuel feed hose.

What about muck on the butterflys from the oil breather? - read somewhere can affect idle quality.

Hi
I googled a few phrases and saw that fuel evaporation was a problem on early cars (via joospeed common problems webpage) however it states that the lines were replaced with metal lined ones run a different way which fixed the problem.

Unless there is a way of checking? Or preventatively fixing?

Just check and see if the fuel lines run anywhere hot? ie close to the manifolds? In the case of the 4.5 over the v to the fuel cooler. (just an example)

Then wrap them in heat reflective material or inside a sleeve.

Mine still suffers this with the lines in the car and fully lagged in the engine bay.

Did you have your air con on as that can delay the onset?

My early 4.2 used to do this. I remember one particular instance after offering to collect the girlfriend at the time from the library. It was a hot day and she had been revising for her university exams.

"Do you want picking up love?"
"In that fking thing?"
"Yes. It's a lovely day and the sun is shining."
"You know I hate it."
"Well it's that or you can catch the bus. It is too nice out there not to be using the Cerbera."
"OK, thanks. See you soon."

So I pull up, turn the engine off and head inside to meet her. She packs her books away, we head outside and back over to the car. I lower myself in to the cockpit enthusiastically, press the black button. She starts, splutters... Then dies. Oh not now - please Cerbie, pleeeease my love, don't let me down now. You know she already holds a grudge for you as you compete for my affection, but this is not the time nor the place. I try again, the starter spins but she just won't catch. Think fast Rob.

"Well it's really hot outside, I fancy an ice cream. There's no rush to be back is there?"
"Good job isn't it."
"Let's go and grab one and make the most of the weather eh!"

She grunts, and we head over to the ice cream van a few minutes walk away. I give her some cash, she queues and I slope away like a scalded cat to make a phonecall on the sly. Track V Road are on speed dial, perfect. We discuss what the issue could be. The plan is agreed, just drag it out Rob. Give it a good half an hour before attempting to turn the engine over and allow the old girl to cool. Eat the ice cream slowly, complain of sensitive teeth or feign an intermittent milk allergy, anything to buy beloved Cerbie some time to compose herself ready for the restart.

So, half an hour passes. I try the black button on return. Nothing. Ohhhhhh Cerbie, I don't mind your mood swings when it's just us, but please not in front of the dragon. This is not the time nor the place for your pettiness. I accept defeat, and mutter those words...

"I'm going to call the recovery services."

At this, the door is opened and she trudges off in a huff, to sit on the red hot concrete steps outside the library. Perhaps she prefers the idea of a heat induced skin graft to standing outside with me in embarrassment. I wait patiently, cursing the Cerb under my breath, bonnet up and bemused. Two young males drive past in a ZR and in unison yell "pile of st!". My ego is bruised and battered. The recovery man turns up, and after a little while of faffing (and calling it a kit car, which almost pushes me over the edge), we got the old girl going and got home in one piece.

Fuel vapourisation was the cause.

That's a great story
It's far better than the cause or the fix
That's what my wife would do that's if she ever came in the cerb
