Team-BHP - Smoke from the engine oil inlet

This is bad news. AFAIK, by no means there should be smoke out of dipstick, unless the rings are worn out.

Also, as for oil consumption, ~300ml per 10000kms is fine, anything more than that is cause for concern.

If it was just smoke from oil filler cap, then the loss of compression neednt be from worn out rings, but as smoke is coming from dipstick (sump), it is cause of concern, and you might be set back by ~50-75,000 at Ford A.S.S.

Please push for warranty ASAP, and get the job done, as there is no way a 45,000 km old 1.4 TDCi rings will wear out, unless its maintained shoddily.

Its been maintained in the best way possible though, no one touches it except for A.S.S and I get it serviced inside 6 months.

There should be no smoke from the engine oil cap at all. I have not seen except when the compression rings or oil control rings are gone. Which means lots of work. (read: money)

Sometimes the PCV system could be blocked , or your grade of oil could be thin. Try a grade thicker. Ford does use thin grades which becomes as light as water.

OT: take 5w30 and 10w40 and put a butane lighter and you will be amazed how thin the oils become. Use the butane lighter for just less than a second.

Not really. If the engine has been running for quite some time with a few high revvs in the mean time, there are slight fumes coming out if you open the oil cap immediately.This is quite normal and acceptable.Happens with almost all cars.

Right! Fumes and hot oil smell is fine , If you see smoke than it is not normal. Kind of hard to tell since we dont have a picture.

True,agreed. Fumes is acceptable but smoke isn't acceptable.Honestly haven't seen smoke coming out with oil cap opened.

My Figo 1,4 TDCi 2011 (27K) also smokes & sprays oil a little when "7I0" cap is opened while engine running.

Found out while adding 3M treatment.

Today i opened the oil-cap a few minutes after starting the engine(cold). I could see some vapours, as well as minute oil spills.

This 1.4 tdci has done just 4k kms.

Both my ikon's(old school 1.8 motor) shows blow-by, but no oil spilling or visible fumes from the oil filler cap.

Maybe it varies from engine to engine.

That leak may not be linked with the subject problem. Find the source and arrest it.
How is the engine bay? Is there any oil visible at valve cover, head gasket area, crank case etc.
Level drop from max to min of dipstick for a oil drain interval is normal. However lodge a warranty claim as I said earlier.
Check also the crankcase ventilation (breather)for probable clogging

Oil splashing is not a concern at all and is normal; an indication of proper lubrication of the OH parts.

Hi all
In my experience some amount of white smoke when oil filler cap is opened in an running engine which is warmed to normal running temperature is normal. It is more like vapors of the warm oil and some splashing due to the rotating cams (for OHC engine) and rocker arms movement.
Please keep in mind it should be like a vapor of oil with no smell of exhaust.
This should be carried out with taking safety precaution that the oil splashing out does not fall on exhaust manifold as that can cause fire. Also the hot splashing oil going in eyes and falling on skin can cause injury.
In light of the above please take adequate safety precaution while doing this test.
Is it possible to check the compression pressure of the engine at the service center ?
Please match the values read from the engine with that mentioned in the service manual. This will give a clear picture if any cylinder has lost its gas tightness.
Also can the lubricating oil pressure of the engine be checked? In a ZEN it is done by attaching a special tool to the oil pressure switch. The tool consists of a flexible hose with the correct thread type at one end and a pressure gauge at the other.
If the oil pressure is low due to say due to clogged filter, oil pump problem, the volume of oil going in the engine parts becomes less. This causes what ever oil going there to get heated to a higher temperature causing the oil fumes when oil filler cap is opened.
Sorry to hear about another FORD in trouble.
All the best mate.

Hi all
Further to the previous reply you can also check the following.
Engine coolant temperature. If in doubt flush out the cooling system using a proper radiator flush and then refill the same as per FORD recommendation.
Is this car equipped with a lubricating oil cooler, same can be checked for performance.
If there is a similar model car in the work shop or somewhere, preferably younger than your car, do the same test and check for result.
As stated in post no 26, can you so kind as to explain for my understanding how a faulty fuel injector can cause lubricating oil smoke to come out of the crankcase.
All the best.
