What is causes of oil leakage in timing compartment

Oil leakage in the timing compartment of an engine can be caused by a variety of factors. Some common causes include:
  1. Worn or damaged valve cover gasket: The valve cover gasket is responsible for preventing oil from leaking out of the timing compartment. If this gasket becomes worn or damaged, oil can leak out of the compartment.
  2. Worn or damaged timing chain cover gasket: The timing chain cover gasket is responsible for preventing oil from leaking out of the timing compartment. If this gasket becomes worn or damaged, oil can leak out of the compartment.
  3. Worn or damaged oil pan gasket: The oil pan gasket is responsible for preventing oil from leaking out of the timing compartment. If this gasket becomes worn or damaged, oil can leak out of the compartment.
  4. Worn or damaged crankshaft seal: The crankshaft seal is responsible for preventing oil from leaking out of the timing compartment. If this seal becomes worn or damaged, oil can leak out of the compartment.
  5. Worn or damaged camshaft seal: The camshaft seal is responsible for preventing oil from leaking out of the timing compartment. If this seal becomes worn or damaged, oil can leak out of the compartment.
  6. Worn or damaged Timing chain tensioner: Timing chain tensioner is responsible for maintaining proper tension on the timing chain. If this tensioner becomes worn or damaged, oil can leak out of the compartment.
  7. Worn or damaged Timing Chain: Timing chain is responsible for maintaining proper timing of the engine. If the timing chain becomes worn or damaged, it can cause oil leakage in the timing compartment.
  8. Low oil level: If the oil level in the engine is low, it can cause oil to leak out of the timing compartment.
It's important to address oil leaks as soon as possible, as they can lead to serious engine damage if left unchecked. To determine the exact cause of oil leakage, it's best to consult with a mechanic or take the car to the service center.

Can a bad timing chain cover gasket cause a coolant leak in my 2003 ford taurus

Yes the timing cover gasket can leak coolant. The coolant passes the waterpump and is pump into the engine block thru the timing cover. to see the actual leak jack up passenger side of car support with jack stand take off wheel and the splash guard now you can see the crank shaft pulley look up at waterpump on both side it goes back to engine block with a mirror you can see it leak.

My 2001 Pontiac montana is leaking coolant when it cool of. Its dripping from the transmition passenger side. I croled underneath and found that the coolant is leaking from the pass side of the engine...

probably a gasket that seals coolant behind cover. I don't remember if there is a freeze plug there.
sometimes a head gasket leak can do the same but not very common.

Overheating, milky oil, oil in coolant...Please help!

Well, the good news is this could be something as simple as a blown head gasket. The bad news is most likely that is not the case. You have either cracked your block, cracked the head, worn a hole in your timing chain cover that is allowing the water and oil to mix or blown your head gasket or a combination of these problems. Your choices are to pull everything apart and magna Flux the Engine block and heads or replace the motor, assuming the issue isn't a hole worn in the timing chain cover, or replacing the motor, the easiest of the solutions although not the cheapest. A decent short block should run around $600 to $1000 with shipping. It's used but has been checked and should serve you for a while. The other option is rebuilding the motor. Should you choose to rebuild the motor I recommend you get the Haynes or Chilton's repair manual on your vehicle for doing the job.

On a 1998 Cavalier 2.4L engine, is the "coolant pump" the same thing as the "water pump"? My coolant pump (under the exhaust manifold) has apparently lost a gasket and is leaking. Is there a rebuild kit or...

Yes the coolant pump is the same thing as a water pump. More than likely your water pump is failing and starting to leek from whats known as a weephole. This repair should be done by a qualified mechanic and takes about 5.5 hours to replace. Only install a new water pump which includes gaskets. U will also need to purchase a timing chain cover gasket set because the pump is driven off the timing chain instead of a rib belt and needs to be removed in order to service the pump.
