Previous owner took a pipe out of my oil system??? Please help!

[Will Watson]

Hi all, first time poster here so bear with me.

Basically I bought a  1997 986 a while back, and decided to change the oil on it this past weekend. It had been running fine and there were no issues when I drained the oil out of the car. When it came time to put the oil back in, I poured the first 5 quarts in with no issue. I then walked back into the garage to grab the rest of the oil. On the way back to my car, guess what? 5 quarts of oil was running down my driveway. I could not for the life of me figure out what happened. I looked underneath the car and couldn't tell where it was coming from, so I decided to roll it back out onto the street, park it for the night, and figure it out in the morning.

(In doing this, I just so happened to crash into the back of my neighbors car because idiot me forgot that you don't have power brakes when the engine isn't running, but that's a story for another time.)

When I took the engine cover off in the morning, it looked like the previous owner just took out one of the pipes in the oil system before it reaches the engine.
It looks like oil was just pouring out of here straight onto the ground,


I'm not 100% positive, but I'm pretty sure this is where the oil is supposed to be going. It looks like the previous owner just capped it off to avoid debris getting into the engine.


I have no idea why somebody would do this, but like it or not I have to deal with it now. Has anybody had any experience replacing this piece? Would this just be a simple elbow joint install, or would I have to replace the whole system? Where can I find a replacement part to fix it? Any help or advice you can give me would be greatly appreciated.

Thanks!
Will

Looks like you probably need a new oil hose 99610725403. Porsche part is $64 on rmeuropean. Other decent sources are PelicanParts or Sunset Porsche Parts. 
 

If you haven’t yet, search the web for the boxster catalog of parts. Should be named KAT520_USA_986_04_KATALOG. It will have the diagrams you need to identify which parts you need, along with part numbers. You might need a couple more things to solve your issue.

996 107 254 03 -- US MRSP (at your Porsche dealer) $71.49

Expect Sunset to be well below that.

I was thinking that might be the part that is missing, but I'm not seeing how such a long pipe would fit into such a short gap. I looked at the diagrams online and something isn't adding up when comparing it to what I'm seeing in my Boxter. Do you happen to have any pictures of what it's supposed to look like?

My guess is that the previous owner cut out the flexible section of the tube and then capped it off.  It was probably torn/leaking in that section and that was his "solution".  There are probably some MacGyver solutions to rejoin the tube sections, but I wouldn't personally mess with it.  I'd just put the right part in there this time around.  I replaced this part on mine many years ago after I damaged it during some transmission work.  I don't remember all the details, but I also don't remember it being particularly difficult.  You can use screw-type hose clamps instead of the oem ones which require the hose clamp pliers ($30 on amazon for a nice one if you prefer to go that route).

This is not your exact model, but gives you an idea of what the hose (red-dashes) looked like before:

Couple of points:

1. How in the Hell was the previous owner changing or adding oil?  As you found out, the normal method does not work, so exactly how OLD was the oil in the engine?  Yikes!
2. I would not be surprised to find out the AOS is probably also dead, as most DIYer's never know that until they can't get the oil fill cap off due to high case vacuum levels, which is impossible with the fill tube cut and plugged.
