I decided to change my pcv that was opening only randomly.I removed the intake manifold (only the metallic part) but when I tried to pull the pcv out of the grommet on the engine, the valve broke in two pieces. I tried to.pull the grommet but it was hardened and broke in pieces leaving part of the valve behind into the hole. Tried to fish it out, but I did not succeed and the remaining part disappeared deeply into the hole, not to be seen again

The panel where the pcv inserts

The hole of the pcv
. I installed a new grommet and a new valve.
The engine runs fine. I am.wondering were that duct leads. Can the part fall into the oil pan? The engine drawings show that the pcv hole is on a metallic "breather cover" that is fixed on the engine side that can be removed, but it sit behind the water thermostat so dismantling is a very long task. Do anybody have a picture of the engine without the cover to better understand if I really need to dismantle half the engine to find the remainings of.the valve? My hope is that it can make its way to engine oil pan and stay there.
Thanks for you valuable help.

 

i don't recall the answer but this has been asked before actually. try a search and see if you can find it..and good luck to you ...

 

Thanks for the answer.I found the thread you mentioned and the pictures in the post are reassuring. The pcv plate cover delimit a serpentine like space that should allow only oil vapours to reach the pcv valve on top. The space seems large enough to not be blocked by the piece left inside. It looks like there are buffle that should keep the pieces out of oil pan. Should for any reason reach the pan it will do probably no harm because oil il sucked trough a fine net that will not allow plastic particles to go in the oil galleries. Should somehow have to remove starter and thermostat housing in the future, I will look behind the plate to remove the missing part. This is a very poor designed part. The material is not made up the place and temperature it will work with. They should have issued a warning to change the valve often to avoid deteriorating, or made valve and grommets more heat resistant and long lasting.

 

For reassurance, you could remove the pcv valve and the new o ring and then put the nozzle from a shop vac or some other vacuum with good suction over the hole and remove any loose jparticulate inside. Whatever you vacuumed out of that hole you'll find in the vac for referance......
