I have an '04 with the metal casing for the oil separator. Nicely enough, it twists out with a pair of channel lock pliers. I replaced the oil separator a couple days ago as part of a valve cover casket replacement and spark plug and wire job, but after some codes and rough exhaust sounds the last couple days, I'm wondering: Did I install the oil separator right?

I had drilled out the old separator, and had to really force the new one in, level by level. I installed it with the long plastic nipple sticking out the open bottom of the metal shaft, and the final semi-circular plastic ring was about flush with the opening of the shaft. Did I install it right? Should it go deeper, where the level is not flush? The other way around?

The AB video only showed an older style Disco oil separator, so I was guessing at putting mine in, but the one I drilled out was facing the same way.

 

anyone have experience with 2011 lr4 oil separator replacement?

 

Even if you instal the oil seperater wrong, or even if it's clogged, won't cause a code,,
But do your gaskets & seals a favor & take it out of tube & just put the empty tube in place, then get a regular PCV valve like fram FV237, & instal it after hollow tube, that way it will never clogg & cleaning it if necessary is very easy,,

 

Anybody ever posted in the LR4 section?

BTW, it's easy. Remove engine cover and intake tube. It's right there.
