getting oil in the air filter.

The car is a 92 ford escort with the 1.9 engine. While checking the air filter earlier today I found it practially full of oil. I left out the new one for now (Not long, of course) till I can find out if it's just build up from previous problems that are fixed, or if the problem there is still happening. How can I check this to see?

BTW, I tried searching the forum, but it kept telling me that the 4th word in the search syntax (out of 6 words) was less that 4 words long. I think the search function here it OOC at the moment of my post.

Thanks

Bruce.

Sounds like you have blowby or a bad PCV valve.

My 2 cents

Sounds like somrthing worse to me.It could be the PCV maybe check it out first and make sure it works and is hooked up.If that is OK your engine is worn out you have what is called blowby.
Worn piston rings.But check the PVC first.

I agree with both posters. Barring PCV troubles, the engine's wasted, rebuild time.

As mentioned, it could be a crankcase ventilation problem (PCV or other blockage), but that much oil is likely blowby. Pull the oil filler cap off and put your hand over it with the engine running. There shouldn't be any pressure or smoke. Either is an indication of the crankcase being pressurized - primary cause is blowby (worn rings, hole in a piston, etc.).

Thanks for the help but

Now I have 2 things that puzzle me,

One: When I put my hand over the oil filler opening as suggested, I get a slight outflow. It stops if I cover it, but if I have my hand oa few inches over the hole then I can feel it.

Two: For some reasn the PCV valve wasn't in it's slot completely. It was hanging loose. (Maybe it shook loose?) It didn't rattle as the Haynes suggested so I need a new one anyway, but is there anything that might have caused it to push itself out that I should be aware of? Dont wanna throw a rod because I missed a warning sign, ya know?

Thanks

You really shouldn't have any air coming out of the crankcase at all. If you replace the PCV and it still does it, then you have bigger issues.

What would cause the PCV to be "hanging loose" is enough crankcase pressure (i.e., a bigger problem) to blow it out. Over time, though, the seals harden and they don't fit to snugly so it could simply have fallen out.

Ok, I put the new valve in and let the engine cool several hours. Now the air coming out is stronger than before. What are these bigger problems and how do I fix them?

There is no easy fix

As stated before there is too much blowby from the engine. The PVC valve cannot keep up with all the pressure so it blows out.
There should be no air coming out or very little from the valve cover or the oil filler cap that is attached to the valve cover.
In short your engine is worn out and needs an overhaul. If you want you can do a compression test but I am sure this will confirm low readings. An engine is nothing but an air pump. If your valves were bad you would be blowing blue smoke from the tail pipe.
