Hello. I have a Ford Ka that has developed a loss of power and seens to be using a lot of oil without and sknoke or oil from the tail pipe.
I thought that I would clean the air filter for the fuel injection and found this to be contaminated with a lot of oil. Any suggestions as to why?

Re: Ford Ka OHV 1.3i Engine
The motor has what is called a positive crankcase ventilation system (PCV - hence the valve). It also has a pipe that goes from the top of the motor to the air cleaner. If your piston rings are well warn, the added pressure that this produces will force a quantity of oil into the air cleaner. A small amount is normal. You are probably losing some oil through the rings as well. The loss of power may be that your compression is low from the bad rings. You can check the compression yourself. They sell compression testers for about 30 bucks. Follow the directions. If a piston does read low compression, squirt some motor oil in the cylinder after the first test. If the reading goes up, that means that the rings are bad.

Sadly without your specific engine make, model & year... I can only speak in vague generalities about contemporary engines...
I don't think your problems are related... I would sooner suspect an oil pump or oil system failure... or a seriously worn engine before... I would believe a single seal could be responsible for that much of a PRESSURE LOSS...!!
I would NOT go to the expense of tearing an engine apart sufficiently to get to the REAR-MAIN without taking in some plastiguage... to check BEARING CLEARANCES.
5 psi on any oil system is seriously impaired.. NOTWITHSTANDING any REAR-MAIN leak...
ought not be able to lose enough oil to drop your entire engine oil pressure... My opinion (I'm just saying)..
Do you mean the oil pan on the underside of the engine?
If you do, then the only real fix is fit a new one. The oil pan may be able to be changed with the car on a lift or over a pit. Pop into a local friendly garage and see what they say.
eeek, sounds like a possible head gasket failure. Check your coolant and oil. If the coolant is low top it off, and if the oil is milky, you are getting coolant in your oil which is usually a bad head gasket.
On 3.0L OHV engines, the oil pressure sensor is located on the left
side of the engine block above the flywheel. On 3.0L DOHC engines the
sensor is located on the left side of the engine block above the oil
filter. On 3.4L DOHC engines the sensor is screwed into the oil filter
adapter. The oil pressure sensor operates the oil pressure warning lamp.

Hope help with this (remember rated this help). Good luck.
