Crankcase air is normal, think about the movement of the pistons... the inside of the engine experiences lots of air movement, normally.

The chocolate milk oil, however, is not good. Something is leaking, most likely at the head. What happened to force head replacement? Is the head correct for your car? It only takes one little passageway in the wrong place.

Do not run the vehicle until you get this resolved or you will kill the engine.

Addeed coolant yesterday today coolant is gone but oil is showing passed full whats going on ?


Your description sounds very much like a blown head gasket or a cracked head/block. This allows coolant to leaking into the oil sump, causing the overfull indication. Check the oil fill cap. If the underside of it has a "chocolate milk" like residue on it, this is the result of oil and water mixing. If this is the case, STOP USING THE CAR IMMEDIATELY. The water in the oil will cause excessive wear on the engine and destroy it in short order. The engine will need to be torn down, flushed, and the cause of the leak found. Only then can it be reassembled and put back into use.

My radiator is lossing water and no sign of leakage


great question, a nice symptoms posted.!!!! and car !
The water, (coolant) can only go 3 places.
1: on the ground, (or at passenger toes, look there)
2: into the inside of the engine (see engine oil turn to milk chocolate shake?
3: in the the A/T tranny pan, same thing same milk.
4: out the exhaust, pipe end point, see steam there ALL THE TIME?

this is short term loss.
long term is normal this is evaporation.
here are the tests.

1: no steam ,tail
2: no carbon or oil in rad neck (cold)
3: milk in pans. per above.
4: rad neck tester (green/blue) chem test unit finds exh. gasses in the rad.
5: same place, RAD leak down tester.
6: compression test. all cyl.
7: cylinder leak down tester can even show me here it leaks (ASK, this is advanced testing methods but easy to do)

1985 Sentra, car is getting hot...changed thermostat, water pump, radiator cap...HELP car is still getting hot!


Check the dipstick and underside of oil filler cap for signs of oil/coolant mixture(chocolate milk).If so, bad news, you have signs of a blown head gasket. Also make sure your radiator isn't plugged. You can check this by running your hand along the surface of the radiator when warm, with the engine off of course. You should not feel any cold spots. I'm assuming your cooling fan(s) are working.

I was told there was a milky film around my oil cap he thought it could be a blown casket


Sometimes condensation will build up on your oil cap...So a milky substance on your cap doesn't necessarily mean you have a blown head gasket. Check your dipstick to see if it looks like chocolate milk. If it does, then you might have a cracked block or head gasket issue.

Ticking & white smoke after replaced intake gasket


Sounds like coolant getting into the combustion chamber. Potential causes in order of significance: Intake manifold gasket (might not have been done right), Head gasket(s), cracked cylinder head, or, cracked engine block. Check the oil. If it looks like chocolate milk it means the coolant and oil are mixing

Car overheated today and began to spill oil. now that I've put water and new oil it doesn't leak but the car shakes when I put it in drive


have you checked the compression on all cylinders?;if two adjacent cylinders are in low range,you may have head gasket damaged. Did you notice oil mixed with vapor on the radiatior cap,oil in the radiator/crankcase (oil looks like chocolate color 'cause of oil/water mixed). Do your spark plugs look like they've been steam cleaned?(from steam in the cylinder head)

Blowing white smoke


white smoke is caused by-- water or anti-freeze entering cylinder . if in radiator or the overflow tank. it will look like a chocolate milk shake. check on oil dipstick for traces of water or anti-freeze. also, a bad head gasket will let water or anti-freeze in combustion area. head gasket symtoms if bad. Symptom #1: Chronic Engine Overheating
Symptom #2: Significant Drop in Coolant Level Symptom #3: Mixing of Coolant and Engine Oil
Symptom #4: White Smoke from Exhaust Pipe

popping of overflow cap Symptom #6: Air Bubbles in Radiator
Symptom #7: Engine Lacks Power GOOD-DAY!

Why does the radiator fluid in my 1991 buick regal look like chocolate milk?


1-If you open your oil cap and seeing a milky stuff at the inside cap, then there is a leak in head gasket. coolant mixed with oil through head gasket leak then vaporize leaving the milky stuff at your cap. 2-If you don't see it then there is possible transmission get into water. When you are running, the pressure from transmission is higher than coolant pressure so it leaks into your coolant thru transmission cooling coil in the radiator. 3-Need to address this as soon as possible since chance of car not running in the middle of a trip is high also consequences of problems are more costly. Good luck.
