*not* an intake or vacuum hose leak. Tech reports the smoke test was negative for any intake and vacuum hoses. That's a relief.
Tech removed the air filter and found leaves in the intake air box and in the tube that runs from the air box to the MAF and beyond. Loaned me his mirror on a stick and helped me aim it I too was able to see the leaves.
When I changed the air filter I couldn't help but have some leaves/trash from the top of the filter element fall into the air box. The air box/filter is a lousy design -- it does a good job of filtering no question -- but serviceability sucks and if the filter element has any trash on it and it will have this trash fall into the air box.
But this is a known, at least to me, for I've changed the filter a few times in the past.
The last time I didn't have access to a shop vacuum -- doing this at "home" where I am not supposed to work on the car at all let alone run a 100ft extension cord to power a shop vacuum -- but I did use a ball of sticky tape on end of a stick to pick up all the leaves and stuff. After I removed all I could see I used a can of compressed air and as I aimed the air blast around I didn't see any other trash in the air box.
Hard to believe I missed something. But hard to believe the leaves were in there from before. I haven't changed the filter myself for a couple of change cycles so this means a Porsche tech left some leaves in there and I definitely can't believe that happened.
But the leaves didn't grow in there either.
Wait a minute: It just occurred to me possibly because the filter was so loaded with trash some leaves didn't fall down into the air box but got trapped -- temporarily -- up high (and out of sight) only to after the filter was installed and the engine run some then fall down. Still my bad for not checking with a mirror.
So the tech is going to remove the intake tube between the air box and the throttle body and clean it out to make sure there is nothing between the plastic mesh and the MAF and to make sure the throttle body isn't fouled with trash.
Lesson is do it right or do it twice. I screwed up not having a shop vacuum handy and not bothering to use a mirror on a stick to check the inside of the air box for any missed leaves/trash.
Car should be done later today but earliest I can pick it up is Friday AM before work.
