Matts 850 GLT Posted January 25, 2006 Report Share Posted January 25, 2006 HiI went to change my air filter and thought I would clean out the throttle body and hoses.When I took off the plastic ducting from the airbox to throttle body, I noticed a lot of oil in that area. So much so that it had seeped out from the join between the air duct and t/b.So, where's it coming from? I cleaned out the hoses and looked for vac leaks but all seemed ok so I tidied the whole area up to see how much oil is coming through the t/b.Is this a sign of bore wear?Any ideas?Matt Link to comment Share on other sites More sharing options...
Ludeless Posted January 25, 2006 Report Share Posted January 25, 2006 I noticed i had some oil in the lines and on the TB when i took mine apart to do the PCV system. It wasn't dripping from out from the hose, but the inside of the hoses did seem to have a decent amount of oil on them. From what i understand, this most likely comes from the turbo.. Although i haven't confirmes that this is the case...or how to resolve the issue. Link to comment Share on other sites More sharing options...
Guest AlvinL Posted January 25, 2006 Report Share Posted January 25, 2006 Yeah, it coming from the PCV flame trap. The PCV fumes can carry a lot of oil. Clean up the flame trap real well. Twist and pull and the flame trap can be disconnected from the intake near the throttle body. There two lines. One's a PCV line (larger) and the other is the vacuum line. The housing is an ABS plastic with no special valve or whatever inside. Only the 'honeycomb'. If that is there, you can remove it using a self tapping screw in the middle and pulling it out. Clean the inside ensuring the vacuum line conection is all clear. You can clean up and unclog all the pores in the 'honeycomb' and re-install or leave it out altogether. It's no longer needed, really.Flame Trap Link to comment Share on other sites More sharing options...
Matts 850 GLT Posted January 25, 2006 Author Report Share Posted January 25, 2006 HiThanks, hmmm, the small white 'flame-trap' got thrown out last summer at the dealers recommendation. No problem as I read a lot of owners don't bother with it anymore. I think I will revert back to using it as I am sure there was less oil in the t/b when the honeycomb flame trap was there.Anyway, I cleaned up the housing and the small hose to the inlet manifold, the small black outlet on the flame-trap housing was blocked so maybe it was preventing vacuum to draw the vapour into the inlet manifold. So I guess the vapour/oil was forced to go through the t/b...Matt Link to comment Share on other sites More sharing options...
