Question about 1999 Daewoo Nubira

1 Answer

Oil leaks between head and block. Removed head. Can't find cause.

99 Nubira 1.6 L - 145,000 K - Oil has been leaking between head and block near oil gallery behind exhaust manifold. We have removed the head but can't find any obvious cause......Both bolts were missing from intake maifold support bracket, and we think an exhaust bracket is missing from front of engine. Could resulting vibration cause oil leak?

We were told by previous owner's mechanic that timing belt did break around 80,000 klms., and bent valves have been replaced, and head shaved...... Are oil leaks like this a common problem? Should we just replace head gasket and bolts and hope for the best?..... We've been told we can't use old head bolts, but manual says we can?.........Any suggestions would be appreciated..............Ideas so far - Head wasn't tensioned down properly?...... Quick bodgey repair done to get rid of car (maybe using old head gasket, bolts were really tight)........ Oil pressure relief valve faulty?

What would leak oil onto the starter


the oil leak could be a bad valve cover gasket needing replacement, a head gasket leaking oil, a leaking intake gasket and oil running down along the engine block and dripping. it could be an oil pressure switch that is leaking. it is near the starter while driving or engine running can spray oil onto the starter. unless the oil leak is very bad and has been leaking a long time onto the starter will not cause it to act like a dead battery even then not likely. have a starter draw test down to check condition of the starter.

I havea daewoo nubira and we replaced the valve cover gasket yesterday , did an oik change and now the engine is smoking white smoke. Try to check to hoses, could not see a leak. Where is the cylinder...


Hello and welcome to FixYa!

The cylinder head is located on the center of the engine. Yes it can be a worn out head gasket or piston rings. If the piston rings are worn out the oil is burnt that's why it emits white smoke. You will need to replace the head gasket and piston rings.

Hope this helps and thank you for using FixYa! Have a good one!

ON MY 1999 DAEWOO NUBIRA I HAVE AN OIL LEAK DOWN BY THE OIL FILTER BEHIND THE LOWER REAR TIMING BELT COVER.IT SPRAY OUT IN A SMALL STREAM WHEN EVER I CRANK THE CAR.


possibly oil pressure switch which has one wire going to it near oil filter or split oil pump gasket or crank seal, might have to remove timming belt cover and crank while cover is off to locate leak

the engine is leaking coolant internally, via either a bad head gasket, cracked cylinder head, or cracked block.

Oil clean, oily antifreeze, blue smoke


Bet it's either a bad head gasket or intake gasket.
Is there any wetness around the area where the engine
head meets the block? Pooling around or near the intake plenum/manifold?

Hi my nubira 2002 is loosing coolant all the time. There are no leaking under the car, the fans come on as it heats up, we have had the water pressurechecked and it is ok and as a precaution we changed the...


is it overheating? this will cause it to preasurise excessively, causing loss of steam through the preasure cap.

otherwise if there is definately no leakage externaly when preasure tested, then it is probably leaking internaly. some cars now have EGR (exhaust gas recurculation) coolers, where coolant cools the exhaust gasses . This can leak, letting coolant into the exhaust system as steam. The only other passage for coolant leakage internally is through a leaking head gasket, or worse still a cracked cylinder head. check your oil on the dipstick, if it is creamy coloured then coolant is leaking into the oil. A headgasket/cracked head may also leak coolant straight into the combustion chamber, the only way to check this is to test for hydrocarbons in the cooling system (specialist test kit)

If the heater matrix is leaking, you would probably notice the front carpets getting damp. .

Engine oil leak between head and block


Cracked head or gasket

Can try re-torqueing the head down just in case the studs have loosened

Oil leaking into coolant -- not head gasket


That vehicle has the transmission cooler built into the radiator. You may not be leaking oil into the coolant, but transmission fluid, they both make the same mess. Replacing the radiator will probably fix your problem. Let me know if this helped.

Oil leakage and hissing sound from nubira 2000


It is quite possible you have a leaking head gasket or intake manifold gasket... allowing both an oil leak and a pressure leak from the cooling system. The alternative may even be as severe as a cracked block. Get it checked before you drive too much farther!!

My 2000 Daewoo Nubira leaks oil from engine


I would think that if the PCV valve were actually plugged, there may be enough pressure build-up to unseat the thing, which would cause most oil leaking from crankcase pressure to exit via the hole left where the PCV was. Just a guess. How many miles on this Nubira?
