Hello people,

Thanks scooby 123! That is a very cool clip!

Last week i addressed a niggle on the SD1. The dashboard lift that is typical for the SD1. I removed the lid and glued it to the steel strip that holds it down. Last Friday i installed it and it looks a bit better i think. I also installed a new temperature sensor on the V8 but when i wanted to turn over the engine i noticed that the engine was wet on the top and smelled fuel. :O I noticed that the little hose that connects the steel pipe to the carburator was leaking. It was an easy thing that the AA could fix and the gentleman was nice to replace the other side as well. Now safe and sound again!

Saturday i visited a mate of mine who is also a huge Rover fan. He filmed the SD1 and uploaded the clips. Enjoy! :D

Very nice Marc!

Does your temperature gauge ever reach 90C? If not a new thermostat might help but i'm guessing the reason for fitting a new sensor was to eliminate the 'stat as the possible cause?
Also have you ever cleaned the breather system? Main areas they block are the flame trap on the right hand rocker cover (it unscrews and can either be cleaned or renewed, it's a service item normally) and the plastic stubs on the carbs where the breather hoses connect. Cleaning them out usually yields gains in both performance and economy and often makes it sound better too - strange but true! Also if they are blocked, they can cause the oil pressure to rise (should be 35psi steady on a hot engine - no more) which causes seals to pop and leak. Check the hoses aren't blocked as well, any blockages here cause problems.
You may well be surprised at the results if there is a blockage anywhere! :wink: :D

Glad you enjoyed "The Liver Run" - shows just how capable and advanced the SD1 was and IMHO still is, just a shame many of them rotted so spectacularly or i might still have one.
Cheers,
Dave

Thank you.

And thanks for your explanation. However, i did my best to understand and i understand the words but i do need images. Is there a manual or file on the internet somewhere? Are these cleaning jobs doable by a amature? And yes i replaced the sensor for that reason. :wink:

Thanks in advance.

I can't find anything dedicated to the breather system Marc so bear with me and i'll cobble together what i can with various reference sources.

http://www.v8tuner.co.uk/product.php?id=721

That's the flame trap/filter that lives on the right hand rocker cover at the front. There is a thick rubber hose going to it, about 25-30mm outer diameter. Remove this hose and unscrew the flame trap. If you follow the thick hose back towards the carbs, you'll find it splits into a "Y" piece, with each arm of the "Y" going via a smaller rubber hose to each carb. Pull these hoses off the carbs and you'll find they are on plastic stubs/tubes fitted to the carbs. This next link shows the hoses i'm on about :

http://www.rimmerbros.co.uk/Item--i-GRID008916

You should be able to see through the plastic stubs on the carbs, if not clean them out either with a small screwdriver or a twist drill bit held by hand or with pliers. Don't use a power drill of any description! If memory serves a 6mm drill bit should be about the right size for this task.

Going back to the flame trap/breather filter on the rocker cover, it should be clear as far as air flow goes, in other words you should be able to blow through it. If not either renew it or clean it by soaking in petrol or similar.

You'll also find what looks like an old fashioned fuel filter behind the main body of the air cleaner - this is also part of the breather system. There is an arrow on the body of this filter indicating direction of flow and this should point to where it connects to the air cleaner. This filter also needs renewing. Any universal fuel filter for a carburettor engine will work but if you can get the Rover version, all the better as it will look right.

It's about 24 years since i last had an SD1 :cry: but i think i've remembered everything - apologies if not! If the breather system hasn't been cleaned regularly then you'll notice the difference afterwards, if it has been cleaned then at least you'll know for future reference.
I hope this is enough to explain the bits that weren't too clear, there's not much (if any) information in the Haynes manual about it as far as i remember but it's a job worth doing. :wink: :D
Cheers,
Dave

You're very welcome Marc - i enjoy your posts and seeing how much care and attention to detail you lavish on your cars.
Let me know how you get on with the breather system?
Cheers,
Dave

Temperature:
Today i checked if the gage is correct. I think there is the problem is right there. i turned on the ignition, took the plug that is connected to the temperature sensor and the gage went to 60 degrees (engine was cold) and stayed there. I think t should go to the end of the scale don't you think? I would say the needle is stuck.

Did you earth the temperature sender plug/wire Marc? If so and the gauge only went to 60C then it sounds as if the needle has been off and refitted incorrectly, stuck or the gauge is not working properly as it should have gone all the way past the hottest point.
Does the fuel gauge register correctly? In other words, if you fill the tank completely does it show a full tank? Just thinking of another possible cause........ :?

Dave

Yes indeed i earth the temperature sender plug.

No the fuel gauge is not correct. And i think the oil pressure is also not correct because when i put the ignition on and not crank the engine yet the pressure is all ready there.

It sounds as if the instrument panel voltage regulator may be at fault. This supplies a steady voltage (usually 10V) to the instruments to prevent the gauges going up and down with battery voltage.
Does the fuel gauge read low as well as the temperature gauge?

Dave

No the fuel gauge always says around 75% full. Even after long drive or after filling up.

This is a weird one Marc - let me have a think on it. Could be a bad earth to the instrument panel i suppose but where to start looking is the question!

I know.
But i will install a replacement gauge cluster unit tomorrow.

That sounds a very good plan Marc - let me know how it goes?
I was going to suggest trying another instrument pack but knowing how hard it is getting hold of spares, didn't think you'd have one!
Good luck with it, hopefully that will fix the problem! :wink: :D
