Cleaning oil trap 850 1996

posted by  someone claiming to be OTK on  Sat Aug 26 15:31 CST 2006 [RELATED]

Does anyone have experience here with cleaning the oil trap (located underneath the intake manifold) - without removing the manifold?

Would using a high pressure spray (of carburettor cleaner) be suitable? This would, of-course, be followed by an oil change.

Regards,
OTK

    It is like a human heart with arteries veins running to it which are clogged up with cholesterol. Spraying it from the outside is futile. You have to open the chest cavity and do a heart transplant along with new veins and arteries...this best sums up the oil trap/pcv replacement...the intake manifold has to come off to do it properly, and don't waste your time and get grimey trying to clean the oil trap. It's cheap enough...just get a fresh one.

    There are 4 openings and the box has a complicated internal structure with baffles. You can't clean any one passage reliably without blocking the others and to do that would require you to remove the oil trap. It takes a little time but is not so very hard. Other post is correct too - both the box and the hoses can be badly clogged, almost anywhere along their length.

    Hi,

    The problem isn't the box getting full/clogged, it's the tubing that gets clogged up and brittle.
