MUST WATCH !!! Is Your Porsche 911 Or Cayman Smoking On Cold Start ??? 

Thanks Nathan for another helpful video.

Always enjoy all your vids. Gonna change the oil on the 997.1 very soon as it's 6 months old.

Such a cool car. Art come to life. Great vid. Always fun to see a nice car treated nicely. haha..

Great stuff Nathan. Common sense and very practical information for me.

Thanks for sharing Nathan.

If your oil level is always at the level at 12:10, you have an over-full situation. If you have too much oil in your engine, the engine will try to flush the extra out, causing smoking among many other bad things. Due to the inaccuracy of the oil level gauge, you really want to keep the level at 1 bar BELOW full. That way you know you're not low or over full. As you stated, not all of the 8 liters comes out, so you really only need to refill with 7.5q. What do you do if you've over filled? Remove the oil filter canister and dump the oil. That will take you down a half bar. If you're a full bar too full, you may have to replace the filter canister, start the engine, and remove the oil in the canister again.

Really enjoyed your vid, I have gen 2 997 911 and has just started smoking (light blue smoke) out of left pipes on a cold start, maybe oil separator or bore scoring

Awsome video bro didn’t look to bad changing it

My 08 cayman was just as bad if not worst when I picked it up. Figure I had to do the AOS since I had same issue on boxster. Within a couple months it just went away. Daily driver.

Speak that knowledge. Good to see the insulation gettin covered

Use a camera to check the bores if you want to be sure.

You should also remember that if the AOS membrane fails badly, you still end up with a pretty contaminated intake after you change the AOS. Need to use the car for quite a bit before the residual oil burns out and the smoke symptom finally disappears. Also, it is a great idea to change the air filter, because it may clog up with oil vapours after a bad AOS failure (even if it is still low mileage and looks relatively clean from dust - it may be restricting your airflow).

Maybe you already figured the smoke at start issue out but I would say its very likely depending on a bad AOS causing oil to go to the intake. I dont know how easy it is to check intake in the caymans but on the std 911 its super easy to check if the intake is moistures with oil. Replacing AOS is another story...

Glad I found you. Great videos! Can you do anything on the coolant system. Understand it’s sealed but is there a proper way to check and add coolant?

Great video. Might start to do my own oil changes. Have been told to use the Mobil 1, 0-40w. And your using 10-40w. H’mm

This really only happens if you start it, go for a short drive (like moving it, or washing it) then start it up again after a long time. It will not do this if you park it after a long drive.

Those taillights look so much better

Awesome video. May Cayman has smoked on cold start in winter only since I got it, and it's not an issue. I have no slapping. I don't loose oil at all. Nothing. Car runs great. My only issue is a tank leak when full. Not sure why these "performance" cars have terrible tanks lol. It's not a cheap thing to fix.

Thanx

I’ve just bought a 2008 3.4S RS 60. 66,000 miles: I got got this smoking on startup for a a few minutes. Engines gets through a little oil. But not much. 2-3 ounces keeps the level up every few hundred miles.

awesome video! I've been looking for a white boxster....but man, I really love the red ....but so do the cops.....I know you live in a more rural area...ever have any issues because the cops like the red too? =)

I have the same white smoke come out more and more often now on startup.. started once a month, once a week now its every startup.. I was told its the AOS but not sure. Oil was changed < 1yr ago and has < 1000 miles on it.

Excellent

Ive always wanted to do my own oil changes.

Hmmmm... That is quite a bit of smoke and it keeps smoking when you drove, as soon as you engaged the gear to drive forward another plume. I'd check with that scope, you may have some issues. Just an observation from my local scene here: old gen 987 caymans now that they are aging quite a bit, sometimes smoke a tiny bit but not nearly that much it's pretty unusual to have clouds of smoke behind you although as 987s go they would be the car to have scoring issues.

Mate how do you stay so clean

I have a 2008 boxster 987 when I start the car there is an overly loud startup soublnd inside the cabin sound like boom boom twice before it starts

Ik have had a 986, 996TT, 987.2 and 997.2 no matter how long they sit they never smoke, ever... Always use 0-W40 Mobil one.

Yes, it turned into oil change. This video did not answer oil thickness helps or not? Just some feedback as I am sitting on my couch🤷🏻‍♂️. I do appreciate your efforts. ✌️

I also have an 08 cayman that does the same thing. I also put a new AOS on mine and still smokes. Mine only smokes though when like backing it out when cold , washing it and pulling back in garage never warmed up. Next morning it smokes on startup just for a couple seconds. Will not smoke at all on long drives when start next morning cold. Where did you get the info that maybe you need to use 10W 40 instead of 0w40 which is all I have ever run in it? By the way, my car only has 40,000 miles and does not use any oil.

Oil change interval? 5000 miles? 6000?

I’m pretty sure I threw away that little cup that goes in the bottom of the oil filter. What’s it purpose and where can I buy another? Part #?

YOU NEED TO CHANGE THE AOS Air Oil Separator ,,, that’s it ,,,,,,,,,,,,,replace that and you are all good ,,, The procedure , 1 just replace the AOS and you are done ,,, but it will smoke for a while ,, to do it Properly remove and clean oil out of plenum remove AOS and replace with new remove coils and plugs, crank the engine a few times to clean out excess oil ,, a good option while your in there replace all coils and plugs if they have been there for years the car will run better and love you for it ,,, replace everything making it all clean from oil run car to burn off excess oils and your done use a good oil 5W 40 Castrol edge MOTUL X-Cess 5W 40… this useful information was brought to you form PORSCHE 997 RETROFIT & CUSTOM

Oil rings🤔

Filter housing needs replaced.

Crank case vent valve, dude.

I'd assume the scoring would be on the bottom side of the cylinder wall since the piston tends to drag on it. You don't put any oil in the canister? Are you sure it calls for 8 quarts or is it 8 litres which which is 8 and a half quarts. My mercs and BMW called for 8 litres. They are European cares and they are all metric. I also use LiqiMoly exclusively. Mobile1 is not actually synthetic.

Meanwhile…on the next episode of ‘keep your OEM parts on your car’.

Did you ever get a good answer on why it smoked I’m looking at one and it does this should I be scared to buy it runs great

Hello sir,u said use 10w40 oil. You just used 10w30 sir 🤔

“How to change oil in a Porsche 987”

Vale seals or stuck open injector. Bad Rings just to name a few

No oil Ring, wrong oil spec sorry but this is just an oil change for 987 cmonnn you can do better !

I would say it's bore scoring and that looking at another series of videos from someone who just had their bore scored Cayman rebuild and stopped smoking altogether even on cold starts and now doesn't use any oil at all, that blue smoke coming from any Porsche isn't "normal" and should be investigated. Don't believe the "oh, every Porsche smokes" nonsense if looking at buying one of these.

I find it a bit worrying that your explanation is that Porsche don't know what viscosity oil belongs in there after building this engine in one shape or another for decades and of course having done extensive R+D and testing. Instead, you should fix your leaky seals. Btw, it always irks me a bit when a professional says "weight". W stands for winter, these are temperate ranges, not weight, Jesus Christ :)

You should create a driveway for the shop

So, why is it that Subarus don’t have this problem?

Anyone else a little annoyed that he cold started the car after 2 days and then instantly backed it out without letting the fluids move through the engine?
