Nissan Sentra GA14 engine - Water in Engine Oil

The GA14 engine was used in a number of Nissan vehicles, including the Sentra and Pulsar. It is a 1.4 liter inline-four engine that was produced from 1985 to 2002.
As for the gearbox, it is likely that the GA14 engine was paired with a manual or automatic transmission, depending on the specific model and year of the vehicle. It is possible that the GA16 engine, which is a 1.6 liter inline-four engine, could also be paired with a manual or automatic transmission, depending on the vehicle in which it is used.
It is important to note that the specific gearbox that fits a particular engine will depend on the specific model and year of the vehicle, as well as the engine size and other factors. In order to determine the correct gearbox for a GA14 or GA16 engine, it would be necessary to consult the vehicle's manufacturer or a reputable mechanic.

No problem. When you depress the clutch, you remove the load from the engine to the cogs and shafts in the gearbox.

Just make sure that your oil levels are correct. In a manual car you can additives like Molyslip to the gearbox.

See , the fuel pump regulator is a sealed unit and all you can do is check for vacuum and hook up a fuel pump tester and check for pressure and volum.

Could be a head gasket that is leaking at an oil passage. Do you have antifreeze in the oil also?

You can buy motor flush at most auto parts stores and use according to instructions and do it yourself or bring to a repair shop that has an engine flush equipment and have it done.

Check the freeze plugs on the engine block.
These plugs/caps can leak when it is not sit perfectly.
Is the leak from tail pipe or from the engine area?
Start monitor for coolant and oil lose and report to the engine supplier.
Can you have a friend to do a drive along to see where the white smoke is coming from?

DO NOT rule out an incorrectly install head gasket set.

Hi,

It would seem that your overheated engine has warped the cylinder head and compression/pressure from the combustion chamber is adding to the pressure of the water/cooling system hence the spitting out. To verify, pls check your oil dipstick and see if the oil has turned to brownish milky color. If yes, then it calls for an engine overhaul, if not possibly air pockets inside engine water jackets.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.
