Primary cover leaking

[Gottaflirt]

I have a 2007 K9 and I have tried to seal the primary cover 4 or 5 times doing it the way the manual instructs and any other way I can think of.
A few years ago I saw in a magazine in it was an advertisement for a improved rubber seal, The difference I noticed in the improved seal was instead of being square shape it was round snd had ribs running the long way. The ribs looked as if they insreraased the amount of sealing service and I wouldn't be surprised iif was a slightly larger diameter. If any one knows a vendor that can get one give a shout.

Whlie the cover is off, take a fine flat file and go over both mating surfaces lightly. Ive had 2 covers that had a lip on the mating surface. Until filing it down, it would never seal. Good luck with the gasket.

Make sure its the seal. Papa Stein had the same issue, so he thought, it turns out the vent was spewing a little and looked like the primary was leaking. Good luck

I use a fine knife sharpening stone to clean gasket material

Try this stuff if you haven’t. It works really well

Thanks for the feedback but if anyone runs across an improved gasket let me know.

I did try the file it didn't seem to help. I also put a layer of black permatex under and over their rubber band. Still no seal poor design. I have no problem with my 2004 with its paper gasket.

You might be able to soak the oring gasket in oil to make it swell to seal better. IDK. Just a thought
