.....not wanting to harp on!

 

Do you think the glow plugs could be causing the exaggerated clattery starting in the mornings as it still does it to a less degree without the box.

No smoke etc . 

Temperatures are up today and I found when I started the car from cold this morning that all the clattering had disappeared so I am thinking my glow plugs need changing, which I am going to do then re fit the tuning box and try again!

nothing to do with glow-plugs. it'll be your cam(lifters) or something.

I get this as well,when engines cold for 1st few minutes. I used comma oil last time & wont ever use it again as i never had a squeek before the oil change.got myself a Ford dealership oil this time.let you know how it goes after an oil change.

Mabee its your teeth chattering with the cold lol

 

I agree that fresh oil change with quality oil can quieten the top end down a bit but there is no hiding the sound of diesel combustion with a cold engine on a cold morning

 

A Mondeo has (almost) exactly the same engine as a Transit or a London black cab/ taxi - so now you know why it sounds like that!  

 

Try a mazda petrol v6 - so quiet i often tried to start it when the engine was already running! (was'nt my car, it was brand new/ i worked at dealarship)

Hi,

The clatter when it was cold outside last week and before then actually retarded the power, i.e. it did not accelerate as quick as when warm, I take it from the above two posts that the lifters are hydraulic, if so then the quality of oil would make a big difference in the cold so next question is....do I put Mobil 1 in or similar for cold weather running?

cheers

You have a very good point - the optimum temprature for economy is (apparently) 192 degrees farenheiet (88.8 degrees centigrade in tests on Ford (diesel!) trucks)  

 

The Mondeo takes "ages" to warm up and when it does the temprature struggles to get much above 60 degrees

 

I don't know the optimum temprature for performance for a diesel but i know its lower than 88.8 degrees but probably higher than 60 degrees

 

The glow plugs only really heat the combustion chamber enough for starting and the engine needs heat in the bores, piston head to run right / run efficiently because it is a compression - ignition engine and requires heat

 

On a cold day when the engine temp drops (normally after running the cabin heater) the MPG can drop too

 

Now that i have a digital temprature gauge/ controller and electric waterpump, im going to experiment with adjusting the temp to find the optimum temp for performance, but im pretty sure the engine does not run well untill 50+ degrees/ runs badly under 50 degrees (gauge starts at 40)

 

The above is for diesel engines, of course, petrol is a different kettle of fish

 

The Mobil 1 / castrol magnatec/ quality oil  should protect the engine better from cold, the engine should be quieter (esp from cold) and last longer before needing an oil change, may even have slightly better performance/ economy

 

The question is - is cheaper oil changed more frequently better than expensive oil changed less often?

I was aiming more at the viscosity of the oil because there obviously seems to be a drag in cold weather on the top end,not getting any symptoms at all now the temperatures have risen,?
