Is it normal for my RS to put out a lot of smoke at startup? It seams to stop after a few seconds.
Thanks

 

Happens a lot Philip. I've heard several technical explanations, but no doubt a characteristic of the car.

 

Phillip my standard GT3 does too. Not all the time but seems to be related to the longer it sits the better the chance it smokes.
In fact my 996 GT3 did the same thing.

 

yeah mine does that too. if it sits all week, then sat morning i take her out.... white smoke comes out for like 20sec. but if i drive it again the next day, no more smoke. there must be soem type of buildup somewhere as the car sits for a few days and clears its self out.... teh first time you start the car after sitting a few days.

 

Sometimes if my friends come down from Humbolt my car will smoke without even getting the key!!!
Amazing!

 

Totally normal

 

GT3 here too, with 2,400+ miles. Guaranteed smoke on start up if it sits more than 4 days.

 

Mine also does it if it sits.

 

Mine smokes after sex!

 

I certainly have been embarrassed by my lovely drive! Only a few Pcar owners now about this “traditional” symptom!

Doesn’t feel like going out with this beautiful girl that at the most indiscrete moment break a wind!

 

I think it's like my old 993 Turbo. If the oil level is near the top, the car smoked, but now that it's in the low-middle range, it no longer smokes. My 993 used to do the same thing, and now the GT3 continues its father's tradition.

 

it's because of the piston clearances in the cylinder head...there's a really long technical explanation but basically because the engine revs so high and the pistons get warm- porsche has to leave a bit of extra room in the barrel for it all to fit at full temp and 8400 revs for a few hours (hot things expand, etc). this is also related to how the engine slops around if/when you lug it in low RPMS as well...(DON'T LUG THE CAR!!)

basically- it's all part of the balance of the rotating parts and such.

when caymans and regular 911's smoke it's from a different cause- because the oil separator is going bad. dry sump engines have much better oiling and don't typically have this problem.

 

CJ nice explanation but my 993TT did the same thing
(makes sense to me )
Does your Andial??

 

no my andial doesn't smoke. in 993TT it's from oil lines leaking into the turbos generally.
