New V8 auto project.

I'm quite pleased with the haul Chris! Unfortunately a couple of issues have arisen on the trip.
I have always had an issue that when the car properly warmed up, there was a lot of heat around the front footwells. I thought this might be coming from the trans tunnel but now I think the heater may be permanently blowing hot air at my feet. I suspect that means the vacuum operated water valve is buggered. :( Also the fan stopped working shortly nefore home.

Next alarming problem; When stuck in traffic, the car started to get warm. Not into the red or anything but certainly into the upper part of the green. Much higher than normal and the oil light came on at idle! Just flickering at first and then staying on. It would go out as soon as I touched the gas and got the revs up to 1000 or so, but the oil pressure gauge was still reading about 28psi. It did this for the whole trip, everytime the traffic got heavy and the temp rose but I suspect that the oil light sender is at fault here because the gauge seems very consistent. I'll change that and see what happens.

Next up was a small clunk coming from under the left rear when I went over judderbars at anything above walking pace. I suspect shock bushes but I'll have a closer look tomorrow.

She did seem quite down on power too. I had set the carbs up just before I left and the timing was knocked back a touch to cope with the 95 octane fuel but she did struggle to pull the trailer and still pinked on steep hills with the extra load. After the trailer was removed she still didn't feel very perky. Accelerating hard out of a corner on a damp road still couldn't produce more than the slightest hint of wheelspin.

My biggest concern is that she does seem to get quite hot in traffic. Not overheating but just a really high underbonnet temp. I suspect the reason for this is that the car has a standard waterpump and 5 blade fan fitted. It should have had a viscous fan fitted originally and I think this is necessary to pull the air through the condenser and around the overcrowded engine bay. Is there any source out there for the right water pump and fan? Even one that can be rebuilt?
At this point I'm considering going for the single scoop look. (Which may happen anyway to tie in with another exciting project. More on that shortly. :wink: )
 
At risk of teaching Grandma, the most likely causes of the overheating in traffic must be a thermostat without the bleed hole / jiggle pin and / or a blocked water passage on the carburettor tower. Plus the state of tune of the engine is likely to be contributing to excessive waste heat. As I recall the subject of upgrading to the viscous fan has been explored in depth here before, and the conclusion was that you really needed the genuine NADA bits as far as the pump goes - but you might get away with a viscous unit from another source. Only likely source for the pump will be Ian Wilson.

There was a recent discussion about the vacuum water valve. Ian reckons you can get away with a manual control one (still available) and that the effect of this is that the final fine tuning of the temperature stability is removed - but it stilll behaves at least as well as a manual control car.

Haven't had a moment to do any work on the car yet but while I was at work today, a mate dropped by in his car and I couldn't resist a couple of impromptu piccies.

His car is a 1971 Triumph 2.5PI, fairly original and still running the injection gear. Mine is a '72 but both cars are white with red leather, power steering and both were auto until he converted his to manual overdrive recently.
He has promised that one day he will put the original wheels with Rostyle hubcaps back on and we can go somewhere scenic and take some decent pics.
 
Lovely photo of your Rover but how did that other bit of tat get in the shot :LOL:

Always admired the late model triumph 2.5's but side by side I know why I own a P6!
