Oil spewing out of the breathers.
I've got oil spewing out of my breathers. Any ideas?

Chuck,
Pics of your set up? Normal set up is that the PCV system takes care of this... -Bill

Check the PCV valve and see if works. That may be your problem. That should not be happening.

Oil out the breathers.
Chuck sounds like you are getting boost into the crankcase. How have you got the crankcase ventilation set up?
Harvey.

I think this is the case. It just started happening, so I don't think it is a problem with my crankcase ventilation, which is ventilated directly to the atmosphere, along with my cam vents. I am thinking either rings as trevor said, or perhaps a hole in the piston. I have had no detonation events that should have caused this. It is an older motor though 135k. It may be time to bite the bullet and just pull the engine and rebuild it. I am also getting a fuel smell from the vent. I seem to miss once in a while as well. I think it is pretty apparent from the folks who are using FI that more is required to achieve this. Intercooling and lower compression for starters.

Chuck,
ouch Have you pulled the plugs to see if they tell you anything? Might also be a good idea to check the timing belt - I'm wondering if the intake and exhaust cams are "off" thus throwing off the combustion event (i.e., raw gas being shot out the exhaust, pressurized crankcase gases being pumped out the vents, ...) -Bill

Plugs
Haven't pulled the plugs since this has occured. I doubt it is a timing belt issue. It has fairly new timing belt, and it was running fine before this occured.

yeah, just trying to come up with something other than "you must have hashed a cylinder" You still might want to check the cam and crank sensors. -Bill

you should also check compression that will tell you once and for all if it is the ring or piston

If it was a piston or ring problem, there would be smoke out the back. No smoke, no problem. The only logical reason is, that there is boost pressure finding its way into the crankcase. You have the cam breathers open, the PCV valve removed/blocked? All the pipes that run from the air duct, near the throttle bodys, to the rear of the block, are removed/blocked? I haven't seen a Pict of your setup, so I don't know what you have got there. Harvey.
