She lives ! / X flow timing question ......
Discussion
Well .... of course a possability that it's electrical. However :
1) I've tried a new (old) sensor, no difference.
2) The little temp gauge stickers put on the core plugs by the engine rebuilders have registered temperatures > 100 degrees
3) When the temperature goes up to 105 or so, the oil pressure takes a dive by 1 bar or so (cheap running in oil)
4) With no thermostat the temperature is stable and consistent .... just way too cold !
Thanks all though for the ideas ....

It's funny you should say that zefarelly ....
Success ! And the cause ?
Well, we all know rule 1 which is :
RULE 1 : just because a part is brand new, dont assume it's okay.
Well, I'm going to add rule 2 :
RULE 2 : just because you buy your parts from a long standing X flow expert, dont assume that the part they supply is the right one !
Whipped the new thermostat out of the car, and compared it to the old thermostat out of the blown engine .... and guess what, the old thermostat is rated at 74 degrees, the new one at 88 ! Popped in the old thermostat and yup, you've guessed it, problem solved. Have just done about 85 miles in her, with a rock steady gauge reading of 80 degrees ... sorted !
Though I'm a bit confused as to why the temperature fluctuated ... perhaps because the new thermostat's opening temperature was so high, the engine would heat up, get too hot, eventually reach the thermostat's opening temperature, which would open and let a flood of cold water through from the radiator, then the thermostat would close up again, until the engine had heated this next batch of water up ... dunno, just guessing.
Thanks everyone for your thoughts and help

Well, the saga continues .... and I'm really losing faith in this car now .....
As you remember, I found that putting another thermostat in solved the cooling fluctuation.
Well, the car is in for it's rolling road session today. The garage has just rung me, and has stopped the RR coz she was pressurising her coolant at high revs. A quick test later, and they've confirmed that the head gasket has gone !!!
This means that either
a) I've warped the head when I had the wrong thermostat in, and f**ked it then (but it was only a 88 degree thermostat), or
b) putting the cooler (74 deg) thermostat in has masked the problem, and it's been there since the rebuild
They're trying to retorque the head (which it would have needed shortly anyway) to see if that solves it .... otherwise it's back to the engine builders ...
{sob}

Well, lets give the place that built it a chance to put the mistake (whatever it is) right first, eh ? They were very good apart from this problem, even picking up and dropping off the engine free of charge
The car's still at the rolling road place .... off to pick it up shortly. Dont want to start taking it apart until I've spoken to the place that built the engine, as that might invalidate the warranty.
My main beef is with the car itself .... I'm sure the f***ers jinxed !!
Can cars be cursed ?

hmm Ive wondered the same myself . . . .6 months of last year getting my MK1 Cortina right from the rad back to the axle . . . .I got there in the end . . . .2 weeks after LeMans . . . .this year Ive been mostly re sorting an apparently sorted TVR Vixen . . . .I finished last night (phew)
I dont think they are, but its impossible to tell how much bodging has been done in the past when you look at and buy a 2nd hand car
