Smoke emissions when starting after a period of non use

Porsche Cayman S - 2009 with 5500 miles sends out smoke after starting following a 5-8hr period of non use. Is this normal? It doesn't continue when driving. I am concerned that this may be a manufacturing fault that may lead to personal expense once the warranty has lapsed e.g valve stem oil seals or something similar.

Actually this is a normal symptom of every Porsche H6 I have owned. I asked the same questions and the dealer stated it was natural to this engine as the cylinders collect a small amount of oil at the bottom every time the car has been run. When you start the engine it is blown out as smoke.

ABSOLUTELY NORMAL, nothing to worry about.

White smoke is water and bluish smoke is oil. Years ago manufacturers used a special break in oil in new engines and it wasn't uncommon for some of this to burn off during break-in. The first oil change fixed that. I don't know that any manufacturers do it anymore. If Porshe does there will be a reference to that fact in your owner's manual.
I think you are on the right track and I would be getting the car back to the dealer, start the documentation paper trail. Make sure you are following Porshe's engine break-in instructions in your owner's manual because they will be able to check some of it from the on-board computer and may be able to void your warranty if they find anything. It's also possible that this problem may go away when you do the first oil change, but it won't hurt to make them aware of the situation. Hope this helps.

2001 ford windstar .Dorman 615-177 kit was installed .It has 350 miles on it since the install but on startup it's blowing white smoke.doesn't stumble ,idles fine and drives fine.Smoke is just brief on...

Valve seal leaks will cause an engine to smoke on start until the oil burns off. If a head gasket were leaking it would be smoking constantly.

White smoke is comming out of the Exhaust Pipe when i start my 911 Porsche Engine. It stays for abaut 3-4 min. and it is like white Fog

can you smell the smoke,does it smell like anti-freez or oil, if anti-freez there would be steam come out or maybe some water out of the tailpipe,you may have a head gasket problem, or crack somewhere in the head. if the smoke smells like oil ,you may need a valve job.your valve guilds may be let oil seep into the camber when setting.when you start the car up the oil is burnt off.

I’m happy to help further over the phone at

When starting vehicle was getting just a *** of blue/white smoke from exhaust after driving a few miles it has turned into a smoke machine billowing sblueish smoke from exhaust this is a not turbo engine.

Blue smoke from the exhaust is cause by coolant\water mixing in the combustion chamber. The smoke will also have a sweet smell to it. A simple way to confirm this is to check your coolant level. Also if you take the radiator cap off while the engine is running you should get exhaust fumes coming out since the mixing will be both ways. Although this is not always the case the coolant can mix with the engine oil as well so check that as well. The oil will have a milky brown color to it.
There are several things that can cause this but the most common is a blown head gasket. It could also include a warped or cracked head as well.

This usually happens after the engine overheated for a prolonged period of time.

You should get this taken care of A.S.A.P.
Hope this helps and good luck.
Please let me know if you need anything else.

Blueish smoke from the exhaust

Blueish smoke is probably excess fuel. If this is the case, the exhaust should smell gassy. I'm thinking that one of the injectors is leaking...something injector cleaner wouldn't solve (you may have to buy a new injector if that's the case). I would check the spark plugs to see if one looks different than the others, that way you can narrow it down. I took my injectors for my porsche to to have my injectors checked and found that a couple of them were leaking so bad they couldn't be fixed. If you send in your injectors to him and any of them are leaky/unrepairable, he won't charge you for them. :)

How many miles is on the engine?
If it's close to 140,000 miles then it's over due for timing chain and timing guide change.
A loose timing chain will offset timing.
Before you do the next oil change. Add a motor flush to clean out the internal parts and free up the rings.
This is the inexpensive method to restore some of the lose compression.
==== Do a 5-10 minutes high rpm highway ran (NO REDLINE).
This will blow out the soot in the exhaust system. ====
Check your vehicle emission batch under the hood.
If it's from California or has California emission then let look for the catalytic converter.
Over time it can become restructed.
As a test,loosen the bolts at the collector pipe and do a short test ran.

Please post any additonal information on the commect window. I will follow up on it.
