If the car is running poorly, smoking, or using oil, then there is probably excess "blow-by". Blow-by happens when the piston rings are stuck or excessively worn. That allows compression and combustion pressure from above the piston to leak past the rings down into the crankcase. On most vehicles, as a matter of pollution control, crankcase fumes are routed back through the engine to be burned. Excessive gases and fumes from the crankcase tend to carry some oil mist with it, hence the show of oil in the air filter passageways.

Well this this will be you valve cover gaskets leaking. Try to feel around or look to see if there is fresh oil around the valve cover. Oil being sucked in to the air filter is a sure sign of a leak in your engine compartment. Check your oil levels also. Hope this helped.

How to install filter


Oil Filter, Air filter or cabin filter?
Oil is done at the same time as changing the oil; it's a simple unscrew it, make sure the mating engine surface is clean (you don't want to leave any part of the old gasket behind), spread a couple of drops of oil on the gasket of the new filter, and screw it back in. Air filter is open the air box, take the old filter out, put the new one in, close the air box. Cabin filter depends on the car for location, but it's also a take out, put in new.
It does help us if you include Year, Make and Model of your car or truck and which filter you want to change.

The car uphill obvious weakness, engine power performance Descent


This is probably due to not cause prolonged oil changes, oil filter, air filter causing incomplete combustion of fuel, increased engine deposits and other issues.
Recommended oil, oil filters, each with about 5,000 km to be replaced once, air filter and oil filter every 10,000 km driving needs to be replaced, otherwise the air, fuel and oil impurities cause parts wear and clogging the oil, thus affecting the normal operation of the engine.
Use obd2 for automotive diagnostics , you can improve vehicle safety performance and driving more safer.

Oil filter location


The oil filter on your 2004 sunfire is under the air intake hose. you take this hose off by loosening the two clamps that hold it onto the air filter housing and the air intake. Under that is a black cap with a large hex head on it, i believe 1.25 inch. that is the oil filter cap. take that off and pull the used oil filter off the bottom.

Purchased focus sport 2006 model no service manual. Mileage 43,000 kms. Need to know service intervals either time/mileage perhaps a copy of the service schedule will suffice.


These maintenance intervals come from the maintenance interval calculator
at www.autozone.com, using a starting point of 25,800 miles (43000 km), and
assuming 1000 miles (1666 km) driven per month, and "severe driving conditions," which
are actually normal usage characteristics, such as frequent short trips, urban driving, waiting in traffic, driving in hot weather, trips under 16 km in cold weather, etc.

1998 Ford Windstar 3.8L ScanTool says that Bank 1 is lean


if your getting oil in the air filter area, you have a leaking intake gasket or a leaking head gasket, run a compression test on it,
if the compression is where it should be on all cylinders then its a leaking intake gasket!!!
