Hey there,

I had a strong suspicion for misfiring and wanted to check sparkplugs, iginition cables and so on. Therefore I had to remove the cover of the ignition coils on passanger side. There is a a pipe from there leading to the oil filler neck. I guess it's for the oil ventilation. I gently pulled the plug but a piece of the plastic cracked and fell inside. I didnt fire up the engine because I am afraid of wrecking something. The piece is about 2x4mm. Is this dangerous and is there anything I can do? I've attached a picture because my english is not the best.

Thanks in advance

If you are morally certain that only plastic went in (and that does seem the most likely) then you're ok. Plastic will melt and deform and not harm the cylinder.

Now if any -metal- (even aluminum) got in there, that's different.

I actually ran a motor once that had a nut in it (which of course I did not know). That turned out very ugly!

Pretty sure that pipe goes into the valve cover. You could take off the valve cover and get the plastic piece out. I don't think it will get hot enough sitting ontop of the head under the valve cover to melt the plastic. There is a good chance it will stay there forever and not hurt anything. But there is also a chance it could find it way into the oil drain pathway from the cylinder head and slow down the oil return. Unlikely that even that would cause an issue.

Me personally, I would pop the valve cover off and get the plastic out. But you're probably fine either way.

P.S. That pipe is a PITA. The only way that I have found to get it out without breaking the tabs off on the inside is to pull straight up with a firm motion.

Hey,

thanks for the replies. We poped off the valve cover but there is another "wall" inside the cover. There is no way to get the piece out (if it's there) but there is also no way for the piece to go further.

Haha wish I got to the this thread before you did that as I just did the exact same thing on Saturday. Same results. I actually pulled the cover and set it on top of the intake. Looked everywhere for the plastic piece. Said screw it, then while putting the cover back on is the first time I looked behind it. DOH, there's a second wall with small slits in it.

But I feel better now, it was worth a try. Anyone knows the part number of this plug? I don't like broken parts in my car.

Had the same issue. I removed the cover, used my $40 wifi endoscopic camera to locate the plastic part, removed it with a vacuum cleaner


I do not agree with the others, removing this plastic part is important, it can plug one oil channels....not likely but it can...


This fitting is unremovable without breaking something by the way...

we had that happen at my shop, pulled the valve cover and got it back

I shook the cover as hard as possible and couldn't hear anything or get it to come out of the hole. I guess I could have plugged all the vents and flushed it out with something. But I hardly doubt it will make it through the small vent slits.

This! At that moment I was curious about the part being inside the cover. I didn't see (edoscope) anything and couldnt hear any rattle inside while dancing samba with the cover
