I went to clean the PCV valve and when I took off the valve the rubber gasket was barely hanging on the block (into which the valve snuggly fits in). I got half of the gasket hanging out and the other half probably went into the combustion chamber and vaporised.

How often does this happen to the rubber gasket? I have to get one from the dealer, provided he is stocking it...

 

i havent had it happen to me at all but i wouldnt worry about it too much, the part is only like 10 from the dealer, just pick another one up and replace it.

 

lol mine fell in ... that happened to me about 20k miles ago

 

can i please get the instruction or diagram with how to replace/clean pcv valves?
i need to clean them soon.

 

The FAQ's stickies should have one. There was also a thread detailing the picture, look to the left of the air filter, there is a hose running to the block, kind off hidden but easily visible right next to the throttle spring assembly.

Can someone post a picture?
