I have replaced the front engine seal twice on my 95 200sx 1.6L, once around 50,000 and again around 160,000. This seems to be an inherent problem with this car that Nissan won't admit. I replaced the seal both times with what Nissan called 'a better seal' but it still leaks to this day. I don't think there is a good solution except if you replace it get the part from Nissan and don't over fill the oil and monitor the amount of leakage. If it gets to bad the oil can get tossed up into the alternator and can ruin the alternator like it did mine at 160,000 miles. I have 200,050 mile on my 95 200sx and still rolling, yes it leaks a little oil.
To replace the front seal on a Nissan 200SX, first, ensure the engine is cool and disconnect the battery. Remove any necessary components, such as the timing cover or pulley, to access the front seal. Carefully pry out the old seal using a seal puller or a flat tool, then clean the area before installing the new seal, ensuring it's seated evenly. Reassemble all components and reconnect the battery.
Need to know what seal you are talking about. Front crankshaft seal, wheel seal, etc?
hard
Sounds like either the windshield seal if defective or the heater core is leaking Check to see if water? is antifreeze
drain the radiator, disconnect the radiator hose from the water pump. disconnect the water pump. lay down the seal connect the new water pump. connect the hose back to the radiator. its pretty easy
Replace the front seal on the pump
You will have to remove the transmission and torque converter from the car to get to the front seal.
how to cahange front pinion seal
remove the trans. and get a seal puller
There are many transmission seals. Front/Rear and pan seal are some. There are also internal seals.
the front or rear seal on the timing chain side
If it is the rear main seal that is leaking, the tranny must be separated from the engine housing.
