It's just a plastic pipe with a rim (like the other end) pushed into a rubber grommet.

Put a screw or hook up the middle and pull it out.

:agree: probably the grommet has gone hard as rock and won't let it go so needs cutting off and replacing... sharp chisel and big hammer job .. Wham bang, job done ... :lol:

Has anyone had to take the cam cover off to get the piece of broken PCV rubber grommet that’s inside?

No, but for a head gasket replacement... yes!
It is not difficult and depending on the age of your cover gasket you could even re-use that, so no cost involved.

if you do: Don't over-torque! (then there are cost involved... :shock: )

Thanks for that about to attempt in now, I actually got the pipe out without the grommet but for some stupid reason I felt compelled to take the grommet out as well. I’m hoping it’s fallen somewhere easy to see once the cam covers off!

Thanks for the response will be attempting this shortly. Fingers crossed the gasket is still useable.

Looking at the manual it says we need to use a silicon gasket sealant in certain spots although the picture in the manual is a bit difficult to work out the length and where the beading is meant to go I’ve seen a thread where some have said put some on the sharp edges near the cams ? Maybe it will become clearer when the covers off.

Only a dot of rtv in the sharp corners for the recess of the cam shafts is enough. :burnout:

I tried to retrieve mine with a vacuum cleaner and some bent wire but didn't quite manage it. It ended up caught behind the baffle in the cam cover but was easy to get out.

Thanks HJ, from looking at the Gasket you must mean these sharp edges :cheers:

I managed to shake the remains of it out of the baffles, it was like playing 'roll the ball' but with half a grommet just without being able to see the grommet.

I was thinking of trying to clean the cam cover up in an ultrasonic cleaner lots of dried burnt oil on the inside...but in not sure whether the Ultrasonic waves may damage the finish of the metal or remove the paint, anyone had any experience with that? Thanks for the responses, just need to order a new PCV valve grommet from SJ's and try and clean the inside of the cam cover and its good to go again.
