Oil filler hose replacement

[alfasteve]

Hi folks,

I'm neck-deep into doing preventative maintenance on my '99 Boxster with 102k miles. It was running perfectly before I attacked it. So, it's got a new IMS bearing and RMS. While the transmission is out everyone says to replace the coolant reservoir tank in the trunk, so I did that today. It went smoothly enough, but I actually got stopped in my tracks at almost the last step.

I simply cannot press the oil fill tube, the one with the accordian kink in it, back on to its mate that goes under the plenum. I pushed as hard as I possibly could, and that oil fill tube hose will not go home. I pushed so hard I cracked its mate that attaches to the top of the engine, so now I get to pull the plenum between the intake manifolds. It was extremely hard to pull off, and I'm finding it impossible to push back on. Clearly I am missing something, but I cannot figure it out. See attached pic. Seems to be lined up ok, but I'm out of ideas.

Thanks in advance,

Steve in LA

Old plastic loses its flexibility. I stick the end in a bucket of hot water for awhile, or use the heat gun to make it a bit more malleable. My nemesis is the intake tube from the filter housing to the engine, always a PITA to reconnect.

That's a great idea, thank you! I got it back on, it was just a matter of getting more leverage. Sometimes it's a good idea to just step away for a while.
I still have to get the new oil fill tube on, the one that bolts to the top of the crankcase. Oh joy.

Thank you,

You are welcome. I had to change the tube that bolts to the top of the engine like you. It was broken when I bought the engine from a recycler... they were very messy in removing the engine, several tubes and wires broken or cut. The install was a real PITA even with the engine out of the car, but I did it without removing the intake manifold or plenums.
