Usually, oil in the discharge air indicates too much oil in the pump or oil too thin (in hot climate use oil treatment). If oil level is known to be correct and oil not to thin, indicates worn cyl /rings. Easy to check. Remove bolts holding cylinder to body/base of pump. Pull off cylinder with head attached to examine piston and rings. Replace parts as needed.

    The oil looks thin, I'm going to try this first, before pull off the cylinder, thank you.

67chevrolet6cly,low compression 2cly,oil blowing out oilcap,is it piston rings or vales

You need to have a basic leak down test done through the spark plug fitting in each cylinder to see where the compression is going.

For each cylinder, set the piston at Top Dead Center.
  • Hook the tester hose directly into the spark plug hole.
  • Hook the leak down tester up to the compressed air hose and zero the pressure.
  • Hook the tester to the hose and take your reading.
You can check where the pressure is going for that particular cylinder by listening for where the air is escaping.
  • If you remove the oil cap and hear a lot of air escaping, the rings are worn and that's where your compression loss is.
  • If you hear it coming out of the intake, the intake valve isn't sealing.
  • If you hear it coming out the tail pipe, the exhaust valve is leaking.
  • If you take the radiator cap off and see air bubbles coming out, you have a combustion leak into the cooling system.

    So have the test carried out on each cylinder and you can pin point the issue in each of the 2 which have tested bad with low compression.

1993 ford festiva leaking oil from air filter

If everything were NORMAL, this would appear to be a case of oil blow-by from the pistons caused by worn-out or broken piston rings. If you witnessed the rebuild then we can rule that out. If you did not and are taking the rebuild on the word of another, it is easy to verify. Perform a compression check and look for low compression in one or more cylinders. The other possibility is that there is an obstruction in the air intake system. Animal can next there, the flapper could be struck, etc. This would cause the engine to pull air through the hose you mention, bringing the oil with it. Normally, this hose only actsd as a vent.

Seems like air is seeping in but also leaking oil on the headers could this be cause of the gasket on the valve covers

Yes, a bad gasket would be the cause of the oil leaking out, but has nothing to do with any air getting in. There is no vacuum under the valve cover. Change the valve cover gasket and check the intake manifold and the vacuum hoses coming from it for vacuum leaks (air getting sucked in).

air boxes usually have a hose coming out of them for just that... to drain the air box of oil or water that gets in it. it doesnt attach to anything, it's just to drain the box onto the ground instead of all over the bike.

I recently purchase a 2004 XC90 with over 200k miles. When attempting to change the oil (a long story) I noticed that the rubber hose connecting the hard plastic air intake(?) that crosses over the top...

This is the turbo air cooler hose and most of them have some oil in them from the turbo. i would replace the hose and keep an eye on it, the problem may be a worn turbo. the turbo is sucking in oil, the turbo may need replacing but i would nt replace it right now, just replace the hose and keep an eye on the engine oil level, if the turbo is working and the engine is not using oil and you dont see smoke coming from the exhaust system when accelerating then just replace the hose for now, hope this helps.

Have oil coming out of the air filter

You may be running too high an oil level. If the problem persists, unplug the breather hose from the air cleaner and route it down so the oil goes to the ground, better yet (and too avoid getting leaked oil on your back tire) buy a small filter and attach it to the end of the breather hose. Most likely the engine oil level is too high though.

Cts won't start after oil change

Had the same problem. 2005 Cadillac CTS with the 3.6L V6 would not start after a oil change. I started looking for wires and stuff that might have been disconnected. That is when I realized that I had also checked the air filter. The hose from the air filter box to the intake had come slightly loose from the intake. The car would not run with an air leak at the air cleaner box box hose. Put the hose on tight and problem fixed.

Air leaks arond trigger when depressed, but no nail fires.

Where does the air leak out from? If it leaks from the trigger DeWalt makes a trigger valve assembly part # 641006-00 list 8.89 BUT if it leaks from other areas we have to look into it deeper. If it is just the trigger valve let me know and I will give you instructions how to remove and install the new one.
