1300 XFlow excessive smoke

[New_Skool]

Hi all,

 

I have a MK2 Escort 1300GL and there seems to be a lot of smoke coming from the engine bay. The temperature is normal and the smoke is constant, from start up and even once warm. It seems to be coming from the dipstick.

 

Could this be a breather problem or am i looking at worn piston rings?

 

Too dark to have a look this evening so will have a better look tomorrow.

 

Also, I have been adding lead substitute when filling up with fuel.

 

Thanks for any advice

The basic answer is excessive crankcase pressure. Too much pressure in the oil gallery can cause the dipstick to literally be ejected, and spew oil-soaked gases all over the place.

 

The causes of the overpressure are several. The easiest (and cheapest) one to check and fix first is the PCV (positive crankcase ventilation) valve. If you put in a new one, my bet is that your problem will be solved.

 

However, if a new PCV valve doesn't get it done, you have more expensive issues at hand. The two primary causes of crankcase overpressure (other than the PCV valve not working) are broken/worn piston rings and worn valve guides and seals. Either condition will cause overpressure in the crankcase, and oily "smoke" to barf out your dipstick tube

as above, plus clean out your gauze in the oil filler cap or replace the cap always helps

Thanks for the responses. Will have a proper look at the old girl on Saturday and see what's up

try a compression test if your concerned about the rings
