Title: Oil breather pipe 'bit'
Post by: GTMaster on January 24, 2011, 08:07:21 PM

Hi,

I noticed in the service manual that in the rocker cover where the pipe sticks out next to the oil filler cap there's supposed to be some sort of 'bit' or 'thingy' (that i don't know the name of) that doesn't let much oil vapour get into the intake through the oil breather pipe. I was wondering what it may be substituted with (i'm guessing as in other cars it's made of metal, like steel wool) as i haven't seen any new ones available. I thought it helps since i pulled the air filter off the other day and saw some oil deposit on the intake pipe directly after the filter.

Also on the side: when i pulled the speedometer drive off the gearbox i didn't notice any seals on the inside  drive axle where the cable connects to. Seems i have a small leak coming from there. Any know otherwise (the cable is a bit flimsy where  it is connected to the drive  but the speedometer works fine).

As a note: I'm onto my fourth half axle rubber boot within approx. 1500kms. If it goes again i don't want to buy this type again. Anyone know a good quality type?

Thanks for any advice in advance.

Check the oil cap has the nylon washer intact, If the oil is coming out around the drive insert, Not sure but I would be looking for an O ring on the shaft or gasket?  Maybe someone else can shed some light on the type of seal?

Are you referring to the flame trap? I think they only cost a pound or two so I would stick with the original part.

Yes that would be it, the flame trap. Anyone know where to buy one? (checked 126fan and axel gerstl but haven't come across it, or maybe didn't notice it....) Just bought a new oil filler cap as the old one's seal wasn't as good as use to be, but the problem was more with the fact that the middle 'stick' piece (the shaft with the spring and washer) was wobbling around and was letting out a bit of oil from time to time.
Thanks for the help and picture  [-/
