Spark Plug Tubes - 986 Forum - The Community for Porsche Boxster & Cayman Owners

Hi all,
I;m doing a 120k service on my '01 Boxster & have broken a spark plug tube.
Do I need to drain & refill the oil now?

So you broke a tube and did not get all the pieces when pulling it out? How big do you think the pieces are?

Upper 1/4 of the tube is missing. Guess I have to drop the sump?

Yeah, something that large would be worth trying to retreive. The good news is that dropping the sump is pretty easy.

Bryan topping · 07-21-2012, 07:29 PM

I thought so. Bummer is I just changed the oil. Fresh 9 qts of Mobil 1

You can "catch" the oil and reuse it. After all, 9 qts of M1 is expensive! Worth buying a clean $5 bucket to do it with.

Just a "stupid" question.
Wouldn't a broken piece of a spark plug tube fall down into the cam cover area first?

Not stupid at all - good point!

You might consider using something like this to get inside the cover and try to remove the pieces:

You might have to pull-out the other spark plug tubes to see and get to the broken pieces.

I got the tube out. This what I have.

Mark_T · 07-22-2012, 12:54 PM

There's a picture that tells a story. What were you using to pull the tube out?

Bryan topping · 07-22-2012, 01:52 PM

I wasn't pulling the tube. Just changing plugs. I went high with the socket & extension heard a snap.

Yager's post at #9 above sounds like a good method.

There are cheaper cameras out there. In fact, I saw one less than $100 in Harbor Freight's ad recently. however, it's both cheap in cost and cheap in quality...

Did notice some snake cams on eBay, cheap since they are USB device and will plug into a laptop. Also sure they are not as great as the ones costing 100's of bucks but how many times will you really use it?

good luck

Did the same thing while changing my plugs and tubes. How did you make out? Did you drop the sump and get the piece out? Has anyone else had this problem?

Steve Tinker · 04-06-2014, 09:57 PM

Dropping the sump will not help much as previously mentioned.
The broken piece(s) will probably be laying inside the valve cover area - they may just remain there or get caught up in the camshafts or timing chain depending on how big the broken bits are.......

mikesz · 04-07-2014, 02:40 AM

Thanks! That is kind of what I figured. I have one more to get out the one closest to cockpit, passenger side. Its very stubborn. I have been using the transom to get them out but this one is tough. Once I am done I am going to go back to the one I broke. I saw some long curved needle nose plier at the auto supply store. Going to see if I can pull the piece out. Nothing on these cars is easy!

Trey T · 04-07-2014, 05:18 AM

It would be nice if Porsche figured out when those tubes should be replaced, like every 50K miles or some-sort....

If there's no interval change, at least use a more durable material like aluminum. I mean ... com'on it's $50K+ car!! You can cheap all you want in the interior department but not the engine!!

mikesz · 04-07-2014, 07:32 AM

yeah I was thinking the same thing. Why use plastic its BREAKABLE. I have been using the transom but the last one is really in there so going to wrap it in sandpaper. I think they switched to aluminum tubes in 04 and so they dont need to get replaced.

steved0x · 04-07-2014, 08:06 AM

I couldn't get the transom to work, but I bought a right angle pipe fitting threaded thingy from Lowe's. I screw the threaded end into the spark plug tube and pull it out. When putting a new tube back in, I use the other end to provide an even pushing force around the perimeter of the tube. And the threads hardly do any damage to the tube if you need to re-use it and can't get the transom to work (and I never got it to work)

Like this, although I am not sure which size it was. I took a spark plug tube with me to Lowes until I found the right size:
