Evaporation Leak

I can't get the car emissions certified till the "visit engine shop" is remedied. I think a year ago it was a loose cap, now tightening it is not solving the problem. The screen at the shop indicated "large evap leak", the technician said that's almost always the cap. I just ordered a new one, you can get just the gasket, but a new one is $15 so I elected to replace it. I will report back to this thread, just started it in case anyone else has the same issue. It won't be surprising to me if at 13 the fine German / TUV approved rubber and or plastic is shot. I love German polymers, "the best or nothing" ! Oh wait that's not Porsche my bad.

Evap update: A new cap arrives Monday. Instead of suffering angst till then I decided to run an experiment. Tighten cap as much as possible, reset codes with the Durametric (anyone else ever find that tool to be fussy sometimes about connecting?) Anyhow once the Durametric gods gave me access I cleared the codes, fired her up. All good. Now if one of you members has a diagram of how the cap strap disconnects from the cap I'd sure appreciate that. I might be able to figure it out by looking at the new part but a diagram would be sweet. Also interesting? It showed no faults, I cleared it twice anyhow and it worked, not sure why it didn't show the code in the Durametric because it 100% did on the dash. "Visit engine shop" not today pal! Whooped em' again Mr. Josey Wales. Be advised if you need a test of said system in your state it will be necessary to drive the car 30 miles one day, 30 the next before you go for a read. PS the drive miles to re populate the read data for emissions was a guess from a Toyota master tech, if the time or mileage on a Porsche is longer or shorter that would be great to know, many thanks P9

In case anyone else ever needs it. There's a small plastic rivet. It's hard for my old eyes to see it properly but this is a huge help. How To Replace Porsche Gas Cap - error code P0442 (youtube.com)

Let my problem help all you avoid one: 175 miles driven not enough to pass emissions test yet. I will report back on just how long it takes a Porsche to accumulate enough data to run the test. Big difference new cap to 13 year old cap. Do yourselves a favor if they have emissions where you live it's 15 at FCP, get a new one before you need one. Playing beat the clock with unknown mileage needs under a time crunch is no fun.

ROAD TRIP!!!!

You know what? I wish it was that simple, I just watched a video of how to do it in 30 minutes and most of the suggestions other than idle to temp will get you killed on any road in any city. It SHOULD not be this hard. The Ford of the same year did it in 80 miles, no drama but not the fu fu car, nooooo that has to be persnickety.

Doing god's work here for the next guy. This is about three times what it takes any other manufacturer. How To Perform a Porsche Cayman Drive Cycle? (RESOLVED - Click To View) My Porsche Cayman won't pass the smog check because the monitors are'nt ready. I had some work done (maintenance) to it recently; nothing emission related, but I think they disconnected the battery at some point. I've contacted the shop but since they didn't do any... tinyurl.com

Received an email from Panorama tech specialist, along with the mileage you need 13 start stops, this aspect of owning a Porsche is unnecessarily difficult under a Evap system evaluation time crunch. PS It was Pedro, patron saint of enthusiasts of Porsche cars and a fine man.

What a nightmare process this is. Soooo happy to live in Florida where no one cares what kind of emissions the car is outputting. The only thing missing, when getting all the monitors to align with the planets, is rubbing your belly while simultaneously tapping the top of your head and chanting...."oh whatta loon I am".

You forgot swinging the dead chicken over your head while you tap it..

Yes Pedro is very help!!. He only has 330,000 miles on his boxster . Good call Boris Art formally "last one" 2008 987.1 BS

A local dealership Service Writer and also an experienced tech, when asked, both said they have no idea of the drive protocol required to reset everything required to get an OBD emissions check. I found that strange. That said, after reading a collection of service training documents in my possession, it is convoluted. Miles are certainly important. "Key starts" come into play. Initial conditions such as air temp, fuel tank level, etc also apply. It's a Hot Mess!

Anyone changing your gas cap and lanyard, one OEM plastic pop rivet is $10. Now I bought a new one because keeping the Spyder pristine and original is important to me. However, after doing it I can relate this to you all: Prepare a small piece of wood skewer from your grill stuff, say 1" with a flat on each end. You can get behind said pop rivet and drive the pin up and out with your fingers. This will allow the deployment prongs to retract. Then you can remove and use the same rivet. The wood will prevent you from any scratching if you were to slip off. Frankly if I hadn't bought one I would have done this but it's one of those jobs you learn from the first time, that's why I'm passing it along. There's no way even a freak car show guy would be able to see that because the back is blind. PS To Harvey, my pal is in the car business, running from 60 you lift off the accelerator, preferably somewhere that you can decelerate to near stop without the brakes, just let the engine do it. This is a critical step for getting the Evap readings you are seeking. I did it a couple times, worked as he said it would.
