Question about 1985 Volkswagen Jetta

1 Answer

Engine oil in air cleaner

1985 VW Jetta (gas powered). A massive amount of engine oil is being pushed from the exhaust into the air cleaner. The air filter is completely soaked with engine oil. This car has some kind of emissions system that re-routes fumes or exhaust back to the air cleaner and somehow oil is being pushed through there. Has anyone encountered this before? What could be causing this? Any help would be appreciated, thanks.

My 2002 vw jetta diesel tdi had a recent oil change and I just checked the oil and it is way high. If I drive it will it mess the car up? I have driven it already but I'm really worried.


If it is grossly overfilled it can damage the engine as well as **** oil into the air cleaner and then the engine, on a diesel this can cause a run away engine because a diesel will burn the oil like fuel.

Why would I occasionally lose power at random times.When starting the engine , every so often I will lose rpms and the car will stall.


1/ Massive air leak in intake pipe to throttle body.

2/ Bad electrical wire to rear of cylinder head as engine rocks on it's mounts.

3/ Oil pressure too high holding valves open....new oil pump required.

4/ Loose/cracked connection of idle air hose under manifold.

Loss of power on acelaration


There's a lot on any car that can cause loss in power.
A few of them are:
Mass air Flow sensor
Bad O2 sensors
Old oil or sludged oil
Bad Gas
Clogged catalytic converter
Loss of cylinder pressure or compression

I would start with the cheapest tests/fixes first
oil: if you haven't already and don't know the condition of your oil, change it. If your oil has sludge in it then you could have a leacking head gasket.

Next up, If your gas is bad fill the tank about half way and use lucus oil octane booster, and for a second half a tank pour in some seafoam engine cleaner. It will clean your fueling system, injectors, and pistons/chambers.

If those too don't help: get a compression test on the cylinders. Not expensive to have done, but could be expensive to fix if there is something wrong or the compression is leaking.

Next, go to a muffler shop and have your catalytic converter checked. A clogged or bad Catalytic converter may trap exhaust and keep it from exiting your exhaust system.
While your there you can have your O2 sensors checked.

If all of that is fine, replace the O2 sensors and the Mass air flow sensor. These components control the air fuel ratio. If they are going out your engine won't ever get the right amounts of gas and air to run properly.

It's a lot, but my general rule of thumb for trouble shooting any issue with a car is to start with the cheapest fix and work your way up.

Changed oil in 05 vw jetta and exhaust light came on.


Hi Dohn. The save levelto fill you oil is 3/4 from empty on your dip stick. This gives the engine space to breath. What has most likely happened here is, the engine has had too much oil and is trying to find a way out which will end up on your drive or through yor exhaust.
