Bubbles In Oil
I have just noticed some small bubbles in my engine oil but there is no sign of it being coolant. I have shown it to a local garage and they say it is nothing to worry about and they see it all the time. Has anyone had any experience of this? Any information will be appreciated.
Thanks Guys.

Are you using a CI-4 rated oil? If not this might be the cause. CI-4 oil has a great antifoam (air) properties. Also are you checking right after shutdown? If you are then this is normal.

Over filling can also cause foaming.................This info from a Ford expert.
DieselDon
Oil consumption, and the proper checking of the oil levels in Ford diesels comes up periodically. Ford dipsticks are calibrated for hot oil. The 10 quarts in the IDI engines expand about 1/2 to 3/4 of a quart as the oil heats up, and contracts the same amout after cooling. If you check the oil first thing in the morning ( which I grew up doing ) the engines will all indicate oils level below full, but when checked hot, will ( after a 10 minute drain time ) the oil level is usually at full. If you are checking the oil cold, and keeping the level at full, you are actually over filling the engine which will burn of the extra rapidly.
Suggestion: Check oil hot after 10 minute drain time.
Don't add until level reaches add line ( 2 quarts ).
In my days at Ford this often cured, or at least improved, the apparent oil consumption complaints.
