How do you change a head gasket on a 99 daewoo lanos 1.6l dohc?


Find a service manual for that model or others with similar engine. Follow the instructions given. You will need to remove the cylinder head first which involves removing a lot of items including the timing belt/chain. Best done by a qualified mechanic.

I have been told that you have to replace the head bolts when replacing the head gasket because the bolts will stretch. Is this true?


If you change the head bolts that's the safest bet for trouble free operation. But, I've changed head bolts on Hondas for years and they never stretched. I know this is for a Kia. My best guess is that it's not necessary since the Chilton based manuals don't say to do this.

If the head is torqued down to specifications and it leaks, then I would say, otherwise. Even torque is more important than bolt stretch, especially if the bolts don't stretch so much that the head gasket can't be tight against the head and block.

Water in the oil


Two common causes are intake gaskets and cylinder head gaskets.
Most times this can be isolated by doing a compression or cylinder leakdown test. Otherwise, the intake needs to come off before removing heads....Carefully inspect the intake gaskets around the water passages for signs of coolant bypass or deterioration. If you find any, likely that is the problem. If you find any engine oil in the cooling system, that points to a head gasket.
Reason for this common problem is simply that aluminium belongs in race cars not on street cars...It's growth rate is too radical and causes too much lateral movement, as well as swelling and shrinkage for gaskets to remain sealed. Gasket manufacturers have dealt with this pretty well but it has not been solved completely.
Intakes leak at a rate of about 4 to 1 compared with head gaskets from what I've seen, so most likely that's where you will find the problem.
Coolant can cause bearing damage so after completing the repair, make sure you change the oil BEFORE starting the engine. In severe cases, I use cheap oil, change it, run it at idle, then change it again, to purge any that remains inside lifters and galleys. Then use a good quality oil when finished. (don't forget the filter!)
good luck

Intake manifold gasket / replace


3.8L Engine

NOTE The 3.8L (VIN K) non-supercharged engine uses a two-piece intake manifold consisting of an upper air plenum which mounts the throttle body and a lower intake manifold assembly which houses the fuel injectors. The 3.8L (VIN 1) supercharged engine uses a similar lower intake manifold. The supercharger serves as the upper manifold.
Lower Manifold

NOTE Two bolts which fasten the lower intake manifold to the cylinder head are accessible only after the upper intake manifold is removed. These bolts are located in the right front and left rear corners of the lower intake manifold. Remove the upper intake manifold to service the lower intake.
The 3.8L (VIN 1) supercharged engine uses a manifold similar to the 3.8L (VIN K), but the supercharger serves as the upper manifold.
  1. Disconnect the negative battery cable.
  2. On 3.8L (VIN 1) engines, remove the supercharger assembly. Please see the procedure in this section.
  3. Remove the upper intake manifold using the procedure above.
  4. Remove the EGR outlet pipe from the intake manifold.
  5. Detach the engine coolant temperature sensor wiring harness from the sensor.
  6. Remove the lower intake manifold bolts and carefully lift off the manifold.

To install:

  1. Clean all parts well with degreaser, especially the gasket seal surfaces on the upper and lower manifold pieces and between the lower manifold and the cylinder heads..
  2. Install new gaskets to the cylinder heads and new seals to the engine block. Carefully lower the manifold into place. Apply thread-locking compound to the bolt threads. Make sure to install the two hidden bolts in the lower intake manifold. Hand start all bolts, then torque evenly to 11 ft. lbs. (15 Nm). Follow the toque sequence, starting in the center, then working outwards in a circle.
  3. Install the remaining components in the reverse order of the removal process.

Upper Intake Manifold (Plenum)
  1. Disconnect the negative battery cable.
  2. On 3.8L (VIN 1) engines, remove the supercharger assembly. Please see the procedure in this section.
  3. Tag for identification, then remove the right side spark plug wires.
  4. Disconnect the ignition wires from the fuel rail.
  5. Remove the fuel rail. Please see Section 5.
  6. Remove the cable bracket from the intake manifold.
  7. Remove the throttle body.


NOTE Two bolts which fasten the lower intake manifold to the cylinder head are accessible are accessible only after the upper intake manifold is removed. These bolts are located in the right front and left rear corners of the lower intake manifold.
  1. Remove the upper intake manifold bolts and carefully lift the upper intake manifold from the engine.

  2. Install new gaskets to the cylinder heads and new seals to the engine block. Carefully lower the manifold into place. Make sure to install the two hidden bolts in the lower intake manifold. Hand start all bolts, then torque evenly to 89 inch lbs. (10 Nm). Follow the torque sequence, starting in the center, then working outwards in a circle.
  3. Install the remaining components in the reverse order of the removal process.

I discovered water in my oil this morning on my 1999 blazer 4.3 v6 could this be the intake gasket?


It could be an intake manifold gasket causeing this...it could also be a head gasket and/or cracked cylinder head. You can pressure test the cooling system to check the intake gasket, and compression test the cylinders for head problems.. If you have had an overheating problem in the past the cylinder heads and gaskets would mostly likely be the problem....Removing the spark plugs will give you an indication on where the water is entering...the plug will be discolored.
Good luck..i hope this helps..please rate me a fixya.

How do i fix water mixed with my oil


This sounds like a blown cylinder had gasket. Although on some engines you will find core plugs below the rocker coverin the head.
