A bit of a multi part question
After using up my supply of Morris 15w40 diesel engine oil I have moved onto Castrol Magnetec 10w40.
Now I don't know if it is a coincidence but I have just noticed a light haze from the exhaust which is obviously engine oil.I am hoping this is from the valve stem seals and not the piston rings.
Now for the questions;
Would you think the change of oil could be the reason,not the "w" part,but the oil make up ie does the Morris oil have more sulphur in the oil helping to condition the valve stem seals?
Or is it just likely to be the mileage on the motor which is nearing 200k?
Has anyone had any positive results from the oil conditioners available claiming to rejuvenate oil seals?
Finally how much of a PITA is changing the valve stem seals and any other jobs I should consider carrying out whilst I am that deep in? ie shims....
Thanks
