Hello Rich,
Welcome to the forum..
It sounds like you are having a lot of "fun" with your P6 even at this early stage. It sounds like a methodical servicing of all the vitals across the entire car may well be in order. A complete flush of the cooling system, chemically cleaned radiator (or recore if required) and a new thermostat should sort out the sudden rise in temp while sitting in traffic for 5 minutes.
Try and fit the proper flame trap hoses if you can, as they have an internal diameter which tapers along the length of the hose. This allows a suction to be formed between the rocker cover and the carburettor.
New fuel, air, engine breather, flame traps, spark plugs,..the lot.
Look forward to seeing some pics,
Ron.

Peter Green is one of my favourite guitarists of all time. He just seems so in touch with what he's playing. I believe it was LSD although from the documentary ( same one you saw at a guess) there were mental problems before that - he couldnt cope with the concept of big business and not being able to do something good with his money)

Hi Ron,
I'm having some fun, but i'm not too stressed about it - just getting it sorted :O) I dont have to rely on the car fortunately... I think you're right about a proper clean/service all over. WHen i checked the coolant after this it had lost some - but i'm not sure the rad cap was on properly - I think i'm going to be dealing with fixing somebody elses poor quality workmanship above all else. Now it runs right the cam tick comes accross as just that.
I think a proper oil flush, coolant flush, new filters (fuel and air ) to start with. Then work out if water is being lost anywhere.
At easter weekend i'll sort the cam, followers and push rods out. A cursory clean of the carbs and get rid of any gunk/oil on the engine so i can see any leaks etc.
I do have some bits of the pipes but i dont think they look right.
I'll upload a picture in a mo :O)
CHeers,
Rich.

A splendid, stately, car. I think the P6 looks particularely good in burnt grey.
A couple of comments on your overheating. A large majority of P6B V8's do this. Certainly start by going down the flushing route and changing any (or all!) hoses that look dodgy as well as the thermostat. You will suffer from coolant loss until you fit an expansion tank - lord knows why they weren't fitted as standard, they were about by the time the car was built. Most people use a plastic SD1 tank. It can be mounted either on the lump of the inner wing against the carb intake elbow or in front of the servo on the drivers side or in front of the coil on the passengers side. Once you have reached this point try it again for overheating. It may well still be there. If so get your radiator recored with a 3 row core instead of the standard 2 row. Any local rad shop should be able to do this easily and cheaply - look in yellow pages. While you're at it get them to fit a rad fan switch from a modern car into the hot, passenger side, tank. Then you're halfway to electric fans if you want to go that route later. The heater is a known weakling. The matrix is only just up to the job and the fan is too small. So by all means recore the heater matrix at the same time. At least one memeber on here has upgraded the fan in the past so use the Advanced search function on here and see if you can find the detail. If not we'll help to a question. Be warned though, dismantling the heater box is a bit of nightmare!
Best of luck

Best be getting to know the suppliers then:
http://www.rover-classics.co.uk/
https://www.jrwadhams.co.uk/index.asp
http://www.winsintltd.co.uk/index.htm
are the principle ones. Not much to choose between Ian at Rover-Classics and Wynns, but I prefer dealing with Ian. Ian's site also has the parts manual in pdf which is excellent for seeing how things fit together.

Not really sure what this means. With a free-flowing matrix they are extremely efficient. Ask Harvey who experienced Bruiser's rodded-out heater the other day. Our 2200's heater has always been very good too. Personally I no longer bother with back-flushing, I just take them down the local radiator shop to either rod or re-core, whichever is neccessary.chrisyork said:
I have a feeling the fan on mine is only just working - definitely couldnt be full power so i'm going to have the dash apart i think and check the levers. ( they are road i think not cables/electric?) I need to do what was suggested and make sure there are no air locks - especially with the lack of expansion tank which has already been pointed out.
I intend to get everything running smoothly as poss at first then gradually bring everything up to scratch over a couple of years.
I love the noise of the engine when the noisy follower quietens as it has started to do( i'm guessing the engine has had the wrong firing order for a while... i cant really understand that someone would manage that but it's right now...)
Can too much oil be used to mask anything apart form the camshaft (i know that often bananas are used for this purpose in the leicester area!)

Sometimes the heater's inefficiency stems from the fact that the flaps within the heater box don't seal as they should.
If you are lucky an adjustment (follow the manual) will sort this. If not, the foam on the flaps would have disintegrated and the only cure is to remove and dismantle the heater box to replace the foam.
When i did this, i took the chance to replace the blower motor with another from an Austin Metro. It seems to be more powerful and has larger and deeper impeler. Not exactly a straightforward swap, but doable if you are determined.

Hi Demetris, I shall bear this in mind. I'll follow the obvious order of trying to clean what i have up and then work out which part(s) aren't performing... Metro is going to be easy to come by so is probably a good one to try.
I know ford enthusiasts look out for Sierra heaters as being extremely efficient so there could be multiple options here...

Funny how the chap who's upgraded his heater motor actually lives in Greece where we Brit's like to go to take advantage of the sunshine. 8)Demetris said:

Yep, we 've got plently of sunshine, but usually in winter, in Northern Greece it can be cold. At the moment we have sunshine with 7 degrees
, but for tomorrow and most of the next week we have forecast for snow / sleet and temperatures around zero :shock: . And under these conditions i don't fancy driving around without a decent heater.Athens is usually warmer though.
As with most things there is always a myth that becomes clear only by personal experience. :wink:

Well PAE 622 F decided it wanted a night out last night. Came out of tesco and she refused to start... faint wiff of petrol which implies its flooded but turned over fine. This morning it wasnt happening either so a short tow later she's home. I think the major mechanics may start sooner than anticipated! On the plus side it's the first time my wife had towed something and says she really enjoyed it!
After we'd got the car home, I took a couple of the plugs out and they were covered in fuel and very black. So running rich and flooded. Cleaned the 2 plugs and the car started for 20 seconds. I probably couldve kept it running using the accelerator pedal, but it's definitely overfuelling as the plugs were soaked with fuel again and there is fuel on the shafts on the underside of one of the carbs.
I think i need to overhaul the carbs - It should be the HS6 carb on this model from what i've seen - is there any way to tell which model they are ( incase someone has modified them)? I'm assuming misadjustment shouldnt cause this?
THanks,
Rich,

Hi,
It's possible that the needle valve has stuck open in the float chamber (assuming its the HS6 and not the HIF variety that I know nothing about ). That would prevent the fuel from being shut off when the float chambers are full and would pump the fuel straight to the carb causing plenty of flooding.
I think that's the best place to look.
