Another overfill maybe?

Searched but couldn't locate definitive answer.

Had a blue puff of smoke come out of my 360 after it sat several weeks. Checked the oil and it was boiling and foamy. The two breather hoses were a little wet with oil. Took the intake off and put a mirror inside the plenum cover. Oil is inside on the bottom. Car runs perfect. No dash lights. Took some oil out of the tank but it smoked again. Do I need to suck out the extra oil from under the plenum covers? Why would the oil seem to boil, that is, inside the tank where the dipstick is, the level went up and down while the engine was at operating temperatures. Did I damage anything? Are the oil seals blown maybe? Car doesn't missfire or run poorly. Quick start ups also. Doesn't smoke while driving.

 

I bought a manual pump kit for $12 today at AutoZone.

I was checking my car, swapping wheels, and inspecting the tightening of bolts after the car got a new F1 power unit.

I put 2 1/2 quarts of oil because the level was low, but forgot that oil is to be checked with the engine running and fully warmed up. So I overfilled by 1 1/2 quarts.

Environmental disaster, the car was smoking on the exhaust as a blown engine, gigantic clouds of blue smoke, scary, small misfires, stupid mistake, but nothing to worry about.

Manually pumped out the oil in less than 2 minutes in the empty two oil containers, then went for a drive, it smoked everything it still had in the intake. Then a few high speed accelerations, and environment is clean again.

Your car is fine, just extract the excess oil.

 

What worries me is the boiling, up/down level of the oil when I looked in the tank. Oil temp good, pressure at 70 when driving, 35 when idling. Could my screen be plugged which isn't allowing the oil to circulate properly or causing the level to go up and down in the tank? How did you get the pump in there and get down to the bottom of the plenum area? Any tips on how to get the oil out using the Autozone pump? I am going to get one today.

 

What exactly is the screen for?

 

I forgot one more question. Is it wise to jack up the front of the car to get the oil under the plenum cover to shift back towards the intake making it easier to get more of the oil out? Is it necessary to get every single drip of oil out?

 

The very early cars had an issue of cavitation (air bubbles) in the oil tank, which was revised. Don't worry about the air bubbles and concentrate on getting the level correct. It should be a little below the maximum mark on the stick once the oil is very hot.

Get as much oil as you can out of the plenums by removing the mass airflow sensors and using a big syringe with a bit of hose on the end.

Even if it stops the smoke, chances are the mass airflow sensors have been contaminated by oil which means replacement in the near future.

 

I removed the intake right up to the butterfly valves. I can see oil in there using a small mirror. I am not sure what the MAF's are but I think they are between the airbox and butterfly valves and seem to snap into the intakes closer to th airbix???. There is no oil that far back so should the MAF's be okay?

Do you recommend jacking up the front of the car to pool the oil making it easier to get more oil out of the plenums?

 

If its dry at the sensor (black tube with a 5 wire plug) then you should be fine. Just get yourself an inspection light and pull as much oil out of the intake as you can using a good sized medical syringe with a bit of small diameter hose on the end.

 

Rustybits, I always have a hard time measuring the oil when the car is running. It's got so many bubbles and frothy.

What I've been doing is getting everything ready, turn off the car, and then check the oil right away. Is this ok?

 

Yes as long as you do it within 30 secs you will be fine...

 

When was the mod made to reduce the froth. I have a late year 04 360. And I almost had a baby when I checked it the first time.

 

This is an interesting discussion. Can you damage your engine by overfilling or is it more of a mess you make????

 

My 360 was over filled with oil by the previous owner. What a disaster. The problems:

Oxygen sensors ruined
MAFs ruined
Oil leaks

the whole job is about $3,000

 

$1,800 here for overfilling by previous owner.

 

Up to a point it is worse to overfill than underfill. If you run a quart or two down without tracking it, your oil temp and pressure will still be nominal. But you can see the misery you can get if you overfill. Therefore be very cautious in adding oil. Make sure the level reading is true with engine running and warm.

 

I tried to explain the issues around over filling and the changes to the disareator here: Ferrari 360 engine oil level checks and the danger of overfilling « Aldous Voice

 

Has anyone ever had an overfill and it not damage anything? May let Tony360 rest easier!

 

100% correct.... not up to a point, but ABSOLUTELY it is better to underfill than overfill a dry sump setup.

Purchased the hand pump at Auto Zone, jacked up the front of the 360 and attempted to pump out any oil. Very little oil came out. I raised the front of the car to get the oil to flow back and puddle where I could reach it with the pump. The air intake had a little bit of oil right where it meets the Plenum covers. The rubber connector tube and entire intake box (s) were oil free. Nothing on/near the MAFs. Should I be good to go? Only about 1 ounce of oil came out.

 

Can anyone help and provide insight?

 

Sounds like you should be OK. Personally, I would have taken off the red plenum covers and stripped back the air intake back to the air filters but that's just me...
