No need to pull the timing chain. Remove drive belt and then remove the crankshaft pulley. use a screwdriver with a piece of cloth wrapped around the tip so you don't damage the seal bore. place the new seal square with the bore and use block of wood or a socket smaller diameter than the seal and a rubber mallet to insert the seal flush with the crankshaft bore. put back on the pulley and tighten according to torque specs in your shop manual then reinstall the drive belt and run engine to check for leaks.
you have a vacumn leak.
water leak or bad thermostat
We are going to need to know where the source of the leak is to help you with that question.
The simple and really only answer I can give you is to find the leak and repair it.
your front windshiald has a leak
replace fuel cap with Nissan only OEM replacement.
Because there is a hole in the hose! Replace the hose
replace the hose or gasket the is leaking, you can spray carb cleaner around the eng whil runnig to locate the leak the eng will try to stall
the valve cover gasket is bad, or the valve cover is loose
It will more than likely leak not make a funny noise. They have a releif for pressure when they go bad.
you may have a loose seal or a pinhole leak i would get it checked out asap
If a 1997 Nissan Altima cuts off at a stop light, there is a problem with the fuel getting to the engine. When you are accelerating, there is pressure and a higher flow of fuel, which is why it won't cut off then. The problem could be a leak in the fuel line, the fuel pump itself, or a fuel filter. It will need to be serviced.
I have a 2002 Nissan Altima and under warranty thank god they had to replace the power steering rack and pinion..also have had a new engine and transmission something done with the rear end under recall..car is a lemon...it could have something to do with the rack and pinion not sure how to fix but probably the answer
if your 1987 Nissan pickup leak water from manifold what do we do
It's probably your Alternator that is going bad. That is if the battery and brake lights came on at the same time.
why is my 2006 Altima blowing cold air when not in motion , example stop light or as soon as it is idling even when it has ran for a long time and the engine is warm. The controls for the "doors"(vent covers that direct the air)are run by vacuum. There cold be a vacuum leak of one of the doors is stuck.
Find a different mechanic, correct plugs? Speedometer disconected at tranmission? Drain plug, filter not tight, gasket at oil pump?
Most likely a fuel leak or sticking injector. Try injector cleaner first to see if it helps. It probably won't but it's worth a try.
depends on where the oil leak is at
Look for gasoline leak at fuel injectors. You can usually smell it. If no leak change air filter. A plugged air filter can cause too rich mixture and too much gas usage. Also inspect gasline from tank to gas filter and around filter.
Some common causes of an oil leak on a Nissan are the gaskets and seals. Both break down over time and must be replaced.
Replace the entire windwo rubber or put soom Gook in the leak. You have to find the leak.
